| History | After a refit in the UK HMS Unique (Lt. Robert Evelyn Boddington, RN) left Holy loch on 7 October 1942. She was ordered to patrol in the Bay of Biscay while on passage from Britain to Gibraltar. She left her escorts off Lands End on the 9th and was not heard from again. The cause of her loss is unknown. She was reported overdue on 24 October 1942 when she failed to arrive at Gibraltar. Possibly lost on 13 October 1942 during a failed attack on the German tanker Spichern in the Bay of Biscay in position 46°54'N, 06°03'W after being damaged by a premature explosion of one of her own torpedoes (see events below for more details). |

21 Jan 1941
At 1340A/21, while close inshore to the west of Tripoli, in approximate position 32°51'N, 12°35'E, HMS Unique (Lt. A.F. Collett, RN) sighted two westbound transports of approximately 2500 tons escorted by two auxiliary schooners bearing 035°. Enemy course was 290° at 12 knots. An attack was started but after an hour the attack was abandoned due to the long range and broad track angle (140°).
This must have been the transports Marocchino (Italian, 1524 GRT, built 1920) and Prospero (Italian, 971 GRT, built 1904) and the Italian auxiliary schooners V 87 / Aosta (562 GRT, built 1913) and V 39/Giovanna (158 GRT, built 1910) which had departed Tripoli for Trapani around 0945A/21. (5)
22 Jan 1941
HMS Unique (Lt. A.F. Collett, RN) attacked a merchant vessel with one torpedo about 10 nautical miles west of Tripoli, Libya. The torpedo missed and the target fled back towards Tripoli.
This was the transport Dielpi (Italian, 1520 GRT, built 1912) who was missed astern but she reported turning back to Tripoli because of the bad weather.
Before this attack an attack on a large transport had to be broken off.
1300A/22 - In position 32°55'N, 13°00'E sighted a large transport bearing 260°. Enemy course was 095° at a speed of 14 knots. Range was 13000 yards. A Cant Z501 flying boat was overhead. Started attack.
1342A/22 - The attack had to be broken off when the enemy changed course, a pity as the target appeared to be 7000 to 10000 tons in size. A second ship was now spotted and the attack was shifted to this vessel which was of about 2000 tons. enemy course was 250° at a speed of 9 knots.
1356A/22 - Fired one torpedo from 700 yards aimed just forward of the funnel. Upon firing Unique went to 75 feet. The torpedo was not heard to explode.
1417A/22 - Returned to periscope depth and saw the target returning towards Tripoli with signals flying. (5)

8 Feb 1941
At 2319A/8, HMS Unique (Lt. A.F. Collett, RN) received HMS Ursula's (Lt. A.J. Mackenzie, RN) signal timed 1940A/8 which gave the following;
Unsuccessfully attacked convoy 3 merchant
ships escorted by 2 torpedo boats in position 35°15'N, 11°30'E. Course 135° at 11 knots.
HMS Unique was not in a position to intercept the enemy. (12)
10 Feb 1941
At 0320A/10, east-north-east of Kerkennah, in position 34°54'N, 11°55'E, HMS Unique (Lt. A.F. Collett, RN) sighted three large merchant vessels bearing 245° at 14000 yards. Enemy course was 350° at 14 knots. Due to the flat calm sea and bright moonlight it was declined to attack dived at 5.5 knots on course 300°.
At 0530A/10, the enemy appeared to alter course to 320° round No.4 Kerkennah Bank buoy. HMS Unique was still 6000 yards from the enemy on a very broad track and the attack was broken off. On surfacing at 0415A/10, seven ships had been visible. The additional four vessels are thought to have been escorts. At 0435A/10, an enemy report had been made.
This convoy was most likely the one made up of the (troop) transports Conte Rosso (Italian, 12567 GRT, built 1912), Esperia (Italian, 11398 GRT, built 1920), Marco Polo (Italian, 12567 GRT, built 1912) and the transport Calitea (Italian, 4013 GRT, built 1933). They had departed Tripoli around 1830B/9 for Naples. They were escorted by the Italian destroyers Luca Tarigo, Lanzerotto Malocello, Freccia and Saetta. (5)
11 Feb 1941
HMS Unique (Lt. A.F. Collett, RN) attacked a large transport east of Kerkennah. This was the German Arcturus (2576 GRT, built 1937) in company with German transports Alicante (2140 GRT, built 1934) and Ankara (4768 GRT, built 1937). The convoy was escorted by the Italian destroyer Turbine and the Italian torpedo boat Orsa on their way to Tripoli from Naples which they had departed around 0930B/8. Arcturus reported three underwater explosions which were probably caused by torpedoes hitting the bottom.
0110A/11 - In position 34°41'N, 11°50'E sighted a large transport and a tanker apparently unescorted, bearing 010°. Enemy course was 160°. Started attack.
0211A/11 - Fired four torpedoes from 2500 yards at the transport. No hits were obtained as the speed was most likely higher then was estimated. After 14 minutes three torpedoes were heard exoloding on the bottom at theend of their run. The 4th torpedo had a gyro failure and was heard to pass over the after casing shortly after it was fired.
0330A/11 - Surfaced. Nothing in sight. (5)
12 Feb 1941
HMS Unique (Lt. A.F. Collett, RN) attacked a transport in a convoy east of Kerkennah with two torpedoes which both missed.
This convoy was probably the one made up of the Italian transports Florida II (3100 GRT, built 1905), Audace (1446 GRT, built 1892) and Pegli (1673 GRT, built 1910) escorted by the Italian torpedo boat Calliope. Thus convoy had departed Palermo around 1000B/11. Initially the convoy had been escorted by the Italian torpedo boat Alcione until the vicinity of Trapani where Calliope took over.
2340A/11 – In position 34°43'N, 11°50'E sighted four vessels bearing 110 degrees in open formation.
2346A/11 - Dived and closed the enemy.
0021A/12 - Fired two torpedoes from 3500 yards. No hits were obtained although two hits were claimed.
0105A/12 - Surfaced, nothing in sight.
----------------------------------------------------------------------------------
1210A/12 - East-north-east of Kerkennah, in position 34°55'N, 11°50'E, two transports were sighted bearing 270°. Enemy course was 160°. Closed at full speed on a 115° track for 15 minutes. The track was then broadened to 130° and the chase was continued for a further 10 minutes but it was found impossible to close the range which was never less than 8000 yards. The targets finally altered course away apparently running into Sfax Bay. The ships were identified as a large tanker of about 6000 tons and a small tramp. They were not escorted and most probably Vichy-French.
----------------------------------------------------------------------------------
1950A/12 - In position 34°50'N, 11°49'E, two small vessels were seen bearing 210°, range 10000 yards. They were at first believed to be trawlers but they may have been small coasters. Unique altered course to 030 and ran away at 8 knots until the ships appeared to round Kerkennah Bank proceeding northwards. (5)
13 Feb 1941
At 0300A/13, east-north-east of Kerkennah, in position 34°49'N, 11°52'E, HMS Unique (Lt. A.F. Collett, RN) sighted a small merchant vessel bearing 290° bull down on course 220°. Decided that a chase was hopeless as HMS Unique was abaft the contacts beam.
At 0356A/13, three small ships were sighted bearing 150° thought to be probably destroyers. The came straight towards at high speed. HMS Unique dived and ran out to the north and east keeping HE end on and astern. Revs. of the enemy were 220 decreasing to 130. No A/S transmissions were heard.
At 0800A/13, in position 34°49'N, 11°50'E, sighted a 6000 tons merchant vessel in ballast bearing 290°. Range was 10000 yards. Course 200°. Closed to attack but the target was subsequently identified as a French 'San Antonio-class' vessel.
At 0830A/13, another merchant vessel was sighted bearing 230°, range 6000 yards. Course of the contact was 030° at 7 knots. The vessel was heavily laden and approximately 4500 tons. Closed to 1000 yards but just then the ship was identified as Vichy-French.
At 1740A/13, in position 34°51'N, 11°49'E, two merchant vessels were sighted. They were less then 2000 tons in size. Range was 14000 yards. Course of the vessels was 040°. They are believed to have been Vichy-French.
At 1908A/13, the Cdr. S'1's signal timed 1755A/13, was received which ordered HMS Unique to retire to the south-west as Swordfish aircraft were operating in her area. She was to remain west of 11°30'E. (5)
14 Feb 1941
At 0230A/14, when south-east of Kerkennah, in position 34°26'N, 11°31'E, HMS Unique (Lt. A.F. Collett, RN) sighted four aircraft flares bearing 055°. HMS Unique set course to return to her patrol area.
At 0345A/14, in position 34°35'N, 11°37'E, a small merchant vessel was seen bearing 045° at a range of 14000 yards. Course of the vessel was 350°. A chase was hopeless. (5)
15 Feb 1941 In an earlier signal, timed 1216A/15, the Cdr. S'1 had ordered HMS Unique to leave patrol so as to arrive off Marsamxett
at 0630A/18. She was to proceed through positions 34°30'N, 12°16'E and 35°32'N, 14°12'E. She was also informed that Mine(s) of unknown type had been laid by enemy aircraft off the harbour entrance. (5) 16 Feb 1941 At 0310A/16, in position 34°25'N, 11°32'E, a transport escorted by a destroyer was sighted bearing 060° at a range of 12000 yards. Enemy course was 180°. Closed on a 100° track and later a 140° track at full speed but the range could not be closed further than 6000 yards.
At 1400A/16, east of Kerkennah, in approximate position 34°38'N, 11°44'E, a merchant vessels was seen bearing 280° at a range of 12000 yards. HMS Unique altered course to close at full submerged speed but after 20 minutes the range had not decreased. A second merchant vessel was just visible hull down beyond the first. They appeared to be ships of approximately 6000 tons each and were probably Vichy-French.
At 1755A/16, east-north-east of Kerkennah, in position 34°50'N, 11°52'E, four vessels were seen bearing 295° at a range of 10000 yards. HMS Unique closed to investigate.
At 1812A/16, the targets were identified as three small minesweepers in quarter line on course 180° at 8 knots. HMS Unique altered course to 080° and kept stern on.
At 1850A/16, HE faded on bearing 220°. (5) 17 Feb 1941 18 Feb 1941 27 Feb 1941 For the daily and attack positions of HMS Unique during this patrol see the map below.
(5) 1 Mar 1941 4 Mar 1941 This signal must have referred to the convoy made up of the transports Adana (German, 4176 GRT, built 1922), Aegina (German, 2453 GRT, built 1922), Arta (German, 2452 GRT, built 1922) and Sabaudia (Italian, 1703 GRT, built 1911). They were escorted by the Italian destroyers Luca Tarigo, Freccia and the Italian torpedo boat Castore. The convoy had departed Naples around 1800B/3 for Tripoli. (13) 5 Mar 1941 At 1330B/5, when in position 33°08'N, 12°02'E, they altered course to 350°. (5) 6 Mar 1941 On closing it was seen that that there were eight in number. Five were thought to be minesweepers and three others were thought to be torpedo boats. They were steering 130°. Ten minutes later two destroyers were sighted bearing 170° at a range of 4 miles. Their approximate course was 280°. Very shortly afterwards they turned eastwards again to a course of about 100°. Asdic gave their revs as 230-240. As far as could be seen they were of the Folgore-class.
During this time four aircraft were flying over the area. At 1212B/6, two of the aircraft, seen to be Savioa's were seen coming straight towards and it was deemed wise to go deep.
From 1235B/6 to 1300B/6, several vessels doing 90 revs were heard to pass to the southward moving east. Others were presumably the sweepers still steering 130°.
At 1245B/6, HE of 140 revs was heard bearing 180° drawing west.
At 1315B/6, HE of 140 revs was heard bearing 180° drawing east.
By 1330B/6, all was quiet.
At 1415B/6, on coming to periscope depth the mast and funnel of a large merchant vessel was seen bearing 140°, astern of a cloud of smoke from presumably the minesweepers. Enemy course was approximately 090°. (5) 7 Mar 1941 7 Mar 1941 The target was soon identified as two torpedo boats of the Spica-class. They were in line ahead proceeding on course 170° at 24 knots (240 revs.). The second torpedo boat was belching forth thick black smoke. (5) 10 Mar 1941 Her escort, the armed merchant cruiser Attilio Deffenu (3510 GRT, built 1929), picked up 14 survivors and four corpses. The destroyer Baleno, escorting a nearby convoy, was detached to hunt the submarine and dropped ten depth charges in the area but without result.
0645B/10 - In position 34°25'N, 12°40'E heard HE bearing 360°. Came to periscope depth and sighted an armed merchant cruiser escorting a laden merchant vessel of about 3500 tons. Started attack.
0659B/10 - Fired three torpedoes at the merchant vessel from 2000 yards. 2 Minutes 15 seconds after firing the first torpedo an explosion was heard. HE ceased immediately. Unique meanwhile went to 150 feet. During the next hour 12 depth charges were dropped but these were not close. No more HE was heard after 0815 hours. (5) 11 Mar 1941 HMS Unique returned to Malta with a defective starboard main engine. This could not be repaired at sea and required a period of repairs at Malta. (5) 28 Mar 1941 For the daily positions of HMS Unique during this patrol see the map below.
(5) 31 Mar 1941 At 0845B/31, in position 36°24'N, 10°57'E a merchant vessel was seen bearing 265° at a range of 7 miles. The vessel was northbound. HMS Unique closed at speed for three quarters of an hour. Vessel was a fully laden tramp of about 4000 tons showing no identification marks or flag. Course of the vessel was 020° at 7-8 knots. Two tubes were blown up, but at the last moment (0943B/31) it was decided not to fire as the vessel was inside French territorial waters. (5) 2 Apr 1941 At 1910B/2, in position 36°36'N, 11°10'E, a small fishing vessel was sighted bearing 285° at a range of 8 miles. Course of the vessel was 020°. (5) 4 Apr 1941 6 Apr 1941 The unknown vessel passed within 4 miles of HMS Unique steering along the coast northwards towards Kelibia at a speed of 7-8 knots. It was a merchant vessel of 5000-6000 tons, well lit, but carrying no visibile identification marks. As the vessel was within French territorial waters she was left unmolested.
At 2030B/6, HMS Unique surfaced. She left patrol at 2200B/6 as ordered in Cdr. S.1's signal timed 1216B/4. (5) 8 Apr 1941 9 Apr 1941 She had only been in harbour for a little over a day but was ordered to sea to intercept and attack an important enemy convoy.
The convoy in question would proceed from Naples to Tripoli and was made up of the transports Andrea Gritti (Italian, 6338 GRT, built 1939),
Barbarigo (Italian, 5293 GRT, built 1930),
Birmania (Italian, 5305 GRT, built 1930)
Rialto (Italian, 6099 GRT, built 1927) and
Sebastiano Venier (Italian, 6311 GRT, built 1940). It was escorted by the Italian destroyer Dardo and the Italian torpedo boats Clio, Enrico Cosenz and Generale Achille Papa.
For the daily positions of HMS Unique during this patrol see the map below.
(5) 10 Apr 1941 At 2009B/10, the Cdr. S.1's signal timed 1540B/10, was received which stated that the convoy was in position 36°10'N, 11°58'E (south of Pantelleria) at 1540B/10 and that Swordfish torpedo aircraft would be operating against it after 2200B/10.
At 2200B/10, HMS Unique arrived in 'Area K' (between Latitudes 34°35'N and 35°25'N and Longitudes 11°00'E and 12°00'E). (14) 11 Apr 1941 2048B/11, Surfaced in position 34°58'N, 11°52'E and sighted three merchant ships and three destroyers bearing 260° at a range of 6 nautical miles. Two were fairly large transports and the other one was a tanker. All were fully laden. A destroyer was ahead of the convoy and two more were bringing up the rear. Enemy course was 160° at 9 knots. The moon was very bright and visibility excellent. HMS Unique closed at 10 knots for 15 minutes on a 110° track.
2110B/11, One of the destroyers was observed flashing a light towards the submarine and was thought to be challenging.
2111B/11- Dived. The range was then about 4 nautical miles and there was a good chance of getting in an attack on the surface.
Before diving (at 2103B/11) the Cdr. S.1's signal timed 1930B/11 had been received stating that a convoy of four merchant vessels and four destroyers had been in positopn 35°26'N, 11.43'E proceeding on course 160° at 12 knots at 1700B/11. Swordfish and destroyers had left Malta to intercept this convoy south of the Kerkennah shallows.
The destroyers in question were HMS Jervis (Capt. P.J. Mack, DSO, RN), HMS Janus (Cdr. J.A.W. Tothill, RN), HMS Nubian (Cdr. R.W. Ravenhill, RN) and HMS Mohawk (Cdr. J.W.M. Eaton, RN).
It was thought the convoy referred to was the same one sighted by HMS Unique and an amplifying report was coded up ready for transmission on surfacing.
2200B/11 - The convoy was now out of sight. It was last seen on bearing 160° steering a course of approximately 130°.
2222B/11 - Commenced attempting to pass the enemy report but it could not be cleared. [HMS Nubian had received it though.]
2345B/11 - In position 34°58'N, 11°48'E sighted a 3000 ton merchant ship in ballast and two small destroyers bearing 180° at a range of 6 nautical miles. Enemy course was 330° at 6-7 knots. HMS Unique closed on a 60° track at 6 knots for half an hour.
2315B/11 - Ceased transmitting. Dived to complete the attack submerged. The attack was progressing favourable, distance off track being 2500 yards on diving but at 2340B/11 the target made a drastic alteration away and the attack had to be broken off.
0010B/12 - The target altered back to course 330° but by this time it was too far away. One destroyer was observed to be lagging behind and at 0020B/12 altered course towards. HMS Unique dived to 50 feet and ran out to the eastward. (5) 12 Apr 1941 In a signal timed 1928B/12, the Cdr. S.1, ordered HMS Unique (Lt. A.F. Collett, RN) to patrol in the south of her patrol area. A convoy of five escorted merchant ships had been in
position 36°32'N, 11°12'E proceeding on course 190° at a speed
of 13 knots at 1730B/12. Swordfish hope to attack
at 2200B/12 subsequently shadowing. Destroyers attacking near Kerkennah after midnight. The destroyers in question were HMS Jervis (Capt. P.J. Mack, DSO, RN), HMS Janus (Cdr. J.A.W. Tothill, RN), HMS Nubian (Cdr. R.W. Ravenhill, RN) and HMS Mohawk (Cdr. J.W.M. Eaton, RN).
The convoy reported was made up of the German transports Ankara (4768 GRT, built 1937), Marburg (7564 GRT, built 1928), Kybfels (7764 GRT, built 1937), Reichenfels (7744 GRT, built 1936) and the Italian transport Calitea (4013 GRT, 1933). They were escorted by the Italian destroyers Ugolino Vivaldi, Antonio da Noli and Lanzerotto Malocello.
By the time HMS Unique received the signal she was in the north-east corner of her patrol area, proceeding east. The move to the south would have meant a probable encounter with the own destroyer coming from Malta and it was decided to continue towards Lampedusa. This decision was reinforced by an enemy report received at 2217B/12 that the southbound convoy had turned to the north-east. (14) 13 Apr 1941 At 1200B/13, course was altered to the westward to get on to the direct convoy route from the Pantelleria area to Tripoli. (5) 14 Apr 1941 15 Apr 1941 18 Apr 1941 21 Apr 1941 2 May 1941 For the daily positions of HMS Unique during this patrol see the map below.
(5) 3 May 1941 4 May 1941 The ship sighted was one of the cruisers of a cover force for a south and later a northbound convoy to and from Tripoli. This cover force was made up of the light cruisers Eugenio di Savoia, Emanuele Filiberto Duca d'Aosta and Muzio Attendolo. These were escorted by the destroyers Antonio Pigafetta, Nicolo Zeno, Nicoloso da Recco, Alvise da Mosto and Giovanni da Verrazzano. (5) 5 May 1941 At 1655B/5, in position 37°52'N, 15°34'E, a fishing vessel was sighted bearing 250° at a range of 5 nautical miles. Enemy course was 050°. (5) 6 May 1941 0900B/6 - Land fixes were taken and it became evident that Unique was more than 25 nautical miles out of position to the south-east. Set course to return to the intended patrol position.
1226B/6 - In position 37°34'N, 15°27'E sighted a party of warships bearing 080°. (These were the Italian light cruisers Eugenio di Savoia, Emanuele Filiberto Duca d'Aosta, Muzio Attendolo. These were escorted by the Italian destroyers Antonio Pigafetta, Nicolo Zeno, Nicoloso da Recco, Alvise da Mosto and Giovanni da Verrazzano ). They were proceeding at a speed of 18 knots. Distance was about 9 nautical miles so an attack was out of the question.
1325B/6 - In position 37°36'N, 15°28'E sighted five large merchant vessels bearing 070°. Distance was about 10 nautical miles. If Unique had been in her intended position shw could have attacked these two enemy forces.
(This convoy was made up of the German transports Marburg (7564 GRT, built 1928), Kybfels (7764 GRT, built 1937), Reichenfels (7744 GRT, built 1936)
and the Italian transports Marco Polo (12567 GRT, built 1912) and Rialto (6099 GRT, built 1927). They were escorted by the Italian destroyers Fulmine, Euro and the Italian torpedo boats Procione, Orsa, Centauro, Cigno and Perseo.
2315B/6 - In position 37°50'N, 15°36'E sighted a small puff of smoke bearing 045° and a faint white light close to it. Course was altered towards to investigate.
2320B/6 - Cape dell'Armi light extinguished.
2330B/6 - HMS Unique was 6.5 miles from the land and as the moon was high and very light it was thought that a ship of any size would have been seen by this time but all that could be seen was an occasional faint white light bearing 055° and then a bright light which flashed twice right ahead. Lights were judged to be a party of fishing boats, or possibly motor torpedo boats.
2335B/6 - Dived to avoid detection. (5) 7 May 1941 9 May 1941 11 May 1941 12 May 1941 14 May 1941 25 May 1941 For the daily and attack positions of HMS Unique during this patrol see the map below.
(16) 26 May 1941 27 May 1941 At 1415B/27, the HE faded out on bearing 005°. (16) 30 May 1941 At 1700B/30, course was altered to 070° to close to investigate.
At 1710B/30, on coming to periscope depth again to have another look nothing could be seen. (16) 2 Jun 1941 At 0800B/2, the smoke resolved itself into four ships, two very small and two larger. They were in line ahead, in a very open formation. Range was closed to about 5 miles. The enemy's course was first assessed at 230°. Later, it however, it was apparent that all four ships were manoeuvring. They were considered to be minesweepers, two possibly Crotone-class (minelayers).
At 0850B/2, the ships were out of sight. They had last been seen on bearing 190° apparently in line abreast steering about 190°.
At 1545B/2, HMS Unique approached Lampedusa harbour on course 050° to investigate. Nothing could be seen in the harbour, except one trawler and one smaller vessel. HMS Unique subsequently proceeded southwards.
At 1635B/2, in position 35°27'N, 12°35'E, an unidentified minesweeper / minelayer, possibly a Crotone-class, was sighted bearing 280° at a range of 6-7 miles. Enemy course was 070°. The vessel was later seen to enter Lampedusa harbour.
At 1825B/2, in position 35°24'N, 12°36'E, two small laden merchant vessels and two trawlers were seen bearing 325°. Enemy course was 070° and these vessels also entered Lampedusa harbour, around 1915B/2. The smoke of two very much smaller vessels was sighted three or four miles astern of the first party, these also entered Lampedusa harbour.
The convoy seen at 1825B/2, was made up of the transports Arsia (Italian, 736 GRT, built 1900), Costanza (Italian, 548 GRT, built 1902) escorted by the auxiliary minesweeper (former tug) G.61/ Costante Neri (100 GRT, built 1914) and auxiliary gunboat (trawler) Graziali Lante (295 GRT, built 1912). The convoy was on passage from Tripoli to Trapani apparently with a stopover at Lampedusa. (16) 3 Jun 1941 Arsia was hit astern and cut in two with only the bow part protruding. The crew of eleven suffered no casualties but the nearby Egusa (275 GRT, built 1913) was damaged by the explosion and the motor fishing vessel Giuseppe Padre had two wounded from splinters.
0440B/3 - Dived and closed the harbour of Lampedusa submerged to investigate and found one of the ships in an exposed position, provided that the boom defences were not effective against torpedoes.
0753B/3 - A torpedo was fired that struck the shore just astern of the ship. Indeed the boom defences were not torpedo proof, so another torpedo was fired at 0822 hours. This was a hit amidships. A big column of water and debris was thrown in the air followed by white smoke.
0827B/3 - A shore battery commenced firing, apparently using HE which burst on the water. 30 rounds were counted. Before going deep to retire to the south-east at speed it was observed that the smoke over the harbour had cleared. Only a foot or two of the midships past of the target only, was visible. The next vessel in the trot appeared to be intact, but it is hoped that she was sufficiently close to be severely damaged by the torpedo explosion. The target had been a well laden, two-welled coaster of about 1000 tons, which had been seen to enter harbour the previous evening accompanied by a similar laden vessel and escorted by two trawlers.
-------------------------------------------------------------------------------------
1650B/3 - In position 35°16.5'N, 12°38'E, HMS Unique sighted a cruiser squadron, most probably Duca Degli Abruzzi and Giuseppe Garibaldi escorted by the destroyers Granatiere,
Fuciliere, Bersagliere, Alpino, but they were too far off to be intercepted and attacked.
This force, escorted by a flying boat, passed within 6 miles and was out of sight at 1720B/3.
In the hope that the squadron would returned before the next day, it was decided to remain on their track all night, instead of leaving for Malta at midnight as had previously been the intention. (16) 3 Jun 1941 This must have referred to a cover force made up of the Italian light cruisers Luigi di Savoia Duca Degli Abruzzi, Giuseppe Garibaldi and the destroyers Granatiere, Fuciliere, Bersagliere and Alpino.
They were covering a convoy made up of the Italian transports Aquitania (4971 GRT, built 1924), Beatrice C. (7015 GRT, built 1920), Caffaro (6476 GRT, built 1924), Montello (6117 GRT, built 1927), Nirvo (5270 GRT, built 1919) and the Italian tanker Poza Rica (7799 GRT, built 1940). The close escort of this convoy was made up of the destroyers Aviere, Camicia Nera, Geniere and Dardo. The torpedo boat Giuseppe Missori sailed from Tripoli at 1215B/2 to meet the convoy and reinforce the escort.
The convoy was attacked in the afternoon by British aircraft during which the Montello was sunk and the Beatrice C. was heavily damaged and later scuttled as she could not be salvaged.
The convoy had sailed from Naples 1730B/1 - 1930B/1 and arrived at Tripoli at 1145B/4 - 1237B/4 (except the two transports which were sunk and Camicia Nera who returned to Naples after finishing off Beatrice C.). (17) 4 Jun 1941 5 Jun 1941 15 Jun 1941 On departure for patrol a practice attack was made on HMS Abingdon (Lt. G.A. Simmers, RNR). (18) 15 Jun 1941 For the daily and attack positions of HMS Unique during her 10th war patrol see the map below.
16 Jun 1941 19 Jun 1941 20 Jun 1941 This was probably the Caffaro convoy on passage from Tripoli to Naples.
This convoy was made up of the transports Caffaro (Italian, 6476 GRT, built 1924) with the damaged torpedo boat Polluce in tow, Nirvo (Italian, 5270 GRT, built 1919) and the tanker Poza Rica (Italian, 7799 GRT, built 1940). They were escorted by the Italian torpedo boats Cigno, Calliope and Generale Achille Papa. This convoy had departed Tripoli around 0630B/19 and was bound for Naples.
1230B/20 - In position 35°33'N, 12°21'E sighted a northbound convoy of three merchant vessels in ballast. The convoy was escorted by three destroyers and three aircraft. The convoy was sighted bearing 125°, range 11000 yards, enemy course was 040°. The convoy soon altered oourse to 010°. The speed of the convoy was estimated at 6 to 7 knots. Closed at speed to attack.
1303B/20 - The convoy altered course to 055°. Two of the escorting destroyers came towards Unique. As the sea was flat calm it is thought that aircraft had spotted Unique while submerged at periscope depth. Between looks Unique went to 50 feet to speed up but non the less it appeared she was detected.
1317B/20 - The attack was broken off and Unique went deep. the convoy meanwhile had altered course to 340°.
1330B/20 - The first depth charge was dropped. 12 Were dropped during the next 20 minutes. One pattern of five was fairly close.
1400B/20 - HE faded out on bearing 320°. Unique meanwhile retired to the north-east at 90 feet.
--------------------------------------------------------------------------------
1650B/20 - In position 35°37'N, 12°29'E, two trawlers and a laden 1000 tons merchant vessel were seen bearing 215° at a range of 5 miles. Enemy course was 150° at 9 knots. These were followed by a laden 3000 tons merchant vessel on a course of about 170°. All ships passed between Lampione and Lampedusa islands.
1740B/20 - The smaller merchant vessel and the two trawlers were observed to alter course as if making for Lampedusa harbour. The second, larger, merchant vessel continued southwards on a course of 170°-180°. (19) 22 Jun 1941 This must have referred to the convoy made up the transports Amsterdam (German, 8673 GRT, built 1921), Col di Lana (Italian, 5891 GRT, built 1926), Ernesto (Italian,7399 GRT, built 1914), Giulia (Italian, 5921 GRT, built 1926), Tembien (Italian, 5584 GRT, built 1914) and Wachtfels (German, 8467 GRT, built 1928). They were en-route from Tripoli (departed around 1500B/21) to Naples and were escorted by the Italian destroyer Lanzerotto Malocello and the Italian torpedo boats Procione, Orsa and Pegaso. (17) 22 Jun 1941 The convoy attacked was made up of the Italian merchants Tembien (5584 GRT, built 1914), Col di Lana (5891 GRT, built 1926), Giulia (5921 GRT, built 1926), Ernesto (7399 GRT, built 1914), the German merchants Amsterdam (8673 GRT, built 1921) and Wachtfels (8467 GRT, built 1928). They were escorted by the Italian destroyer Lanzerotto Malocello and the Italian torpedo-boats Procione, Orsa and Pegaso. The convoy was on passage from Tripoli to Naples. The submarine was first located by
an aircraft and it was the torpedo-boat Pegaso which was detached to hunt the
submarine and carried out the depth-charge attack. She claimed the submarine at
least severely damaged but this was not the case.
1055B/22 - While in position 35°41'N, 12°15'E heard distant depth charges being dropped to the Southward. Looks like the reported convoy was approaching.
1120B/22 - Sighted smoke and one aircraft bearing 140°.
1125B/22 - Sighted one merchant vessel of 6000 tons followed by others that could not yet be identified. Range was about 14000 yards. Three destroyers were seen to be escorting as well as two aircraft.
1203B/22 - The convoy was seen to alter course from 320° to 265°. Destroyers were seen to be closing Unique.
1207B/22 - An aircraft was seen at 1000 feet 3000 yards away. The attack was broken off and Unique went deep.
1210B/22 - Five explosions were heard, most likely the aircraft had dropped bombs or depth charges.
1237B/22 - The first of a group of single depth charges was dropped fairly close. The attack was intensified at 1250, 1255 and 1314 hours when up to 17 depth charges were dropped at a time.
1335B/22 - The 52th depth charge was dropped, this was the last one that was fairly close.
1351B/22 - The last depth charges were dropped. A total of about 80 had been dropped. (16) 24 Jun 1941 This must have referred to the convoy made up of the troop transports Esperia (Italian, 11398 GRT, built 1920), Marco Polo (Italian, 12567 GRT, built 1912), Oceania (Italian, 19507 GRT, built 1933) and Neptunia (Italian, 19475 GRT, built 1932) escorted by the destroyers Aviere, Geniere, Vincenzo Gioberti and Antonio da Noli which was on passage from Naples (sailed at 0400B/25) to Tripoli. The torpedo boat Calliope had joined from Messina to reinforce the escort. Due to the enemy air activity the convoy broke off their passage and diverted to Taranto. A distant cover force made up of the heavy cruisers Trieste, Gorizia and escorted by the destroyers Corazziere, Carabiniere and Ascari was also deployed.
At 2359B/24, HMS Unique (Lt. A.F. Collett, RN) received the Senior Officer Malta's signal timed 2150B/24, ordering her not to proceed to area 'Q' anymore. She was now to patrol near position 33°25'N, 14°02'E (north-east of Tripoli). Course was set accordingly. (16) 26 Jun 1941 At 1309B/26, she received the Senior Officer Submarines Malta's signal timed 1120B/26, ordering her to return to Malta proceeding through position 35°30'N, 14°14'E to arrive at Malta around 0630B/28.
At 2100B/26, HMS Unique left patrol to return to Malta. (20) 28 Jun 1941 As HMS Unique had still all her torpedoes on board she was sent out again at 2030B/28 to intercept Vichy-French reinforcements proceeding towards Syria. This was her 11th war patrol (9th in the Mediterranean). She was ordered to patrol near position 37°50'N, 16°02'E (south of Cape Spartivento, Calabria).
For the daily and attack positions of HMS Unique during this patrol see the map below.
(16) 30 Jun 1941 At 1630B/30, in position 37°50'N, 15°59'E, smoke was sighted bearing 180°.
At 1650B/30, the smoke resolved into a 6000 tons merchant vessel (like a Cortelazzo-class) bearing 196° at a range of 7 miles. Enemy course was 305° at 12 knots. The enemy ship was not zig-zagging.
At 1915B/30, in position 37°50'N, 15°59'E, a Spica-class torpedo boat was seen bearing 090° at a range of 5 miles. Enemy course was 285° at 17 knots. This was most likely the Italian submarine chaser Albatros returning to Messina from escort duty with the transport Capo Orso (Italian, 3149 GRT, built 1916) which was on passage from Naples to Benghazi. (19) 1 Jul 1941 The vessel sighted was most likely the
At 0600B/1, the upperworks of two merchant vessels were seen close inshore bearing 310°. They were following the vessel sighted half an hour earlier. Once again HMS Unique was already abaft their beam. These ships were difficult to pick out in the hazy light, and against the coast. But even if they had been sighted earlier an attack would not have been possible.
At 0639B/1, 0650B/1 and 0654B/1 explosions were heard to the west [this was HMS Upholder (Lt.Cdr. M.D. Wanklyn, RN) attacking].
At 1200B/1, in position 37°50'N, 16°00'E, a westbound destroyer was sighted bearing 085° at a range of 5000 yards. Enemy course was 275°.
At 1750B/1, in position 37°51'N, 16°01'E, a eastbound destroyer, thought to be Turbine-class, was sighted bearing 180° at a range of 3 miles. Enemy course was 060°, speed approximately 20 knots.
At 2100B/1, HMS Unique left patrol to return to Malta in accordance with the Senior Officer Submarines Malta's signal timed 1120B/1. (19) 3 Jul 1941 17 Jul 1941 19 Jul 1941 Also two practice attacks were carried out on HMS Encounter. (22) 20 Jul 1941 For the daily positions of HMS Unique during this patrol see the map below.
(16) 21 Jul 1941
At 1905A/15, HMS Unique (Lt. A.F. Collett, RN) received the Cdr. S.1's signal timed 1713A/15 ordering her to retire once more to the south-west as Swordfish aircraft were operating in her area. Once again
At 0012A/16, south-east of Kerkennah, in position 34°21'N, 11°28'E, HMS Unique (Lt. A.F. Collett, RN) sighted three destroyers bearing 180° at a range of 10000 yards. They were proceeding northwards. HMS Unique altered course to 030°. HE was not heard until 0055A/16 when it was faint and muffled.
At 0001A/17, HMS Unique (Lt. A.F. Collett, RN) left patrol to return to Malta. (5)
Around 0630A/18, HMS Unique (Lt. A.F. Collett, RN) ended her 4th war patrol (2nd in the Mediterranean) at Malta. (5)
Around 1745A/27, HMS Unique (Lt. A.F. Collett, RN) departed Malta for her 5th war patrol (3rd in the Mediterranean). She was ordered to patrol to the west of Tripoli, Libya. (Area 'Y', south of 34°00'N and west of 12°20'E.)
Around 1235A/1, south-east of Kerkennah, in position 34°21'N, 11°24'E, HMS Unique (Lt. A.F. Collett, RN) sighted a merchant vessel bearing 235°. Range was about 8 nautical miles. Enemy course was 060°. It was not possible to close to attack. (5)
In a signal timed 1845B/4, the Cdr. S.1, informed HMS Unique (Lt. A.F. Collett, RN) and HMS Upholder (Lt.Cdr. M.D. Wanklyn, RN) that at 1530B/4 a convoy of 5 merchant ships escorted by two
destroyers sighted 20 miles north-east of
Marifctinio Island on course 260° at a speed 6 knots.
At 1247B/5, north-west of Zuara, Libya in position 33°04'N, 11°59'E, HMS Unique (Lt. A.F. Collett, RN) sighted six small vessels bearing 096° at a range of 7 nautical miles. They were later identified as one trawler, four auxiliary schooners and a tug in line ahead. Their speed was 11 knots. When first observed they were steering 320°.
At 1140B/6, north of Zuara, Libya in position 33°04'N, 12°05'E, HMS Unique (Lt. A.F. Collett, RN) sighted a party of small vessels bearing 310°.
A signal was supposed to be sent by Malta on 5 March ordering HMS Unique (Lt. A.F. Collett, RN) to leave patrol after dark on the 7th. Due to a mistake this signal was not sent and it was feared HMS Unique had been lost when she failed to arrive at Malta. When she sank an Italian ship on the 10th, this ship sent out an SOS message and it became clear HMS Unique was not lost but returning to Malta as originally ordered in her sailing orders. (5)
At 1655B/7, in position 33°20'N, 12°01'E, HMS Unique (Lt. A.F. Collett, RN), sighted a large amount of smoke bearing 330°. Course was altered to close to investigate.

Collett, RN) sighted a steady light bearing 270° which, on drawing ahead and closer, was identified as a small steamship proceeding northwards along the coast. Although this vessel was two or three miles outside French territorial waters no attempt was made to close as HMS Unique was north of the 'sink without warning' area and the vessel was considered to be Vichy-French.
At 1520B/2, in position 36°39'N, 11°10'E, HMS Unique (Lt. A.F. Collett, RN) sighted a small schooner bearing 120° at a range of 6 nautical miles. Course of the vessel was 360°.
At 0020B/4, north of the Gulf of Hammamet, in position 36°33'N, 11°03'E, HMS Unique (Lt. A.F. Collett, RN) sighted a dark object bearing 226°. HMS Unique ran in until the range was around 6000 yards. The target appeared to be very small, possibly a destroyer or torpedo boat coming straight towards. No bow wave was seen. HMS Unique dived and altered course to southward. No HE was picked up at all and it is not known what HMS Unique now dived for. (5)

Operation Substance, convoys to and from Malta
Passage through the Straits of Gibraltar of the eastbound convoy and sailing from Gibraltar of the remaining ships involved in the operation.
Around 0130B/21 convoy WS 9C passed the Straits of Gibraltar. The convoy at that moment consisted of six merchant ships; City of Pretoria (8049 GRT, built 1937), Deucalion (7516 GRT, built 1930), Durham (10893 GRT, built 1934), Melbourne Star (11076 GRT, built 1936), Port Chalmers (8535 GRT, built 1933) and Sydney Star (11095 GRT, built 1936).
At the time they passed through the Straits they were escorted by HMS Nelson (Capt. T.H. Troubridge, RN), HMS Edinburgh (Capt. H.W. Faulkner, RN, flying the flag of Rear-Admiral E.N. Syfret, RN), HMS Manxman (Capt. R.K. Dickson, RN), HMS Lightning (Cdr. R.G. Stewart, RN), HMAS Nestor (Cdr. A.S. Rosenthal, RAN), HMS Avon Vale (Lt.Cdr. P.A.R. Withers, RN), HMS Eridge (Lt.Cdr. W.F.N. Gregory-Smith, RN) and HMS Farndale (Cdr. S.H. Carlill, RN).
HMS Manchester (Capt. H. Drew, DSC, RN), HMS Arethusa (Capt. A.C. Chapman, RN), HMS Cossack (Capt. E.L. Berthon, DSC and Bar, RN), HMS Maori (Cdr. R.E. Courage, DSO, DSC and Bar, RN), HMS Sikh (Cdr. G.H. Stokes, RN) departed Gibraltar around 0200B/21 escorting troopship Leinster (4302 GRT, built 1937) which was to join the convoy. However Leinster grounded while leaving Gibraltar and had to left behind. The small fleet tanker RFA Brown Ranger (3417 GRT, built 1941, master D.B.C. Ralph) left Gibraltar around the same time escorted by the destroyer HMS Beverley (Lt.Cdr. J. Grant, RN).
About one hour later, around 0300B/21, HMS Renown (Rear-Admiral R.R. McGrigor, RN, flying the flag of Vice-Admiral J.F. Somerville, KCB, DSO, RN), HMS Ark Royal (Capt. L.E.H. Maund, RN), HMS Hermione (Capt. G.N. Oliver, RN), HMS Faulknor (Capt. A.F. de Salis, RN), HMS Fearless (Cdr. A.F. Pugsley, RN), HMS Firedrake (Lt.Cdr. S.H. Norris, DSO, DSC, RN), HMS Foresight (Cdr. J.S.C. Salter, RN), HMS Forester (Lt.Cdr. E.B. Tancock, DSC and Bar, RN), HMS Foxhound (Cdr. G.H. Peters, DSC, RN), HMS Fury (Lt.Cdr. T.C. Robinson, RN) and HMS Duncan (Lt.Cdr. A.N. Rowell, RN) departed Gibraltar to give convoy for the convoy during the passage to Malta.
At sea the forces were redistributed; Force H, the cover force HMS Renown, HMS Nelson, HMS Ark Royal, HMS Hermione, HMS Faulknor, HMS Foresight, HMS Forester, HMS Fury, HMS Lightning and HMS Duncan.
Force X, the close escort for the convoy HMS Edinburgh, HMS Manchester, HMS Arethusa, HMS Manxman, HMS Cossack, HMS Maori, HMS Sikh, HMAS Nestor, HMS Fearless, HMS Firedrake, HMS Foxhound, HMS Avon Vale, HMS Eridge and HMS Farndale.
Plan for the operation
Force H was to cover the convoy until it reached the narrows between Sicily and Tunisia. Force X was to escort the convoy all the way to Malta. Ships of Force X also had troops for Malta on board that had been taken to Gibraltar by troopship Pasteur. On 23 July 1941, the day the eastbound convoy would reach ‘the narrows’ five empty transports and two tankers would depart Malta for Gibraltar (Convoy MG 1) The seven empty transports were; Group 1 (speed 17 knots) HMS Breconshire (9776 GRT, built 1939), Talabot (6798 GRT, built 1936),
Group 2 (speed 14 knots) Thermopylae (6655 GRT, built 1930), Amerika (10218 GRT, built 1930),
Group 3 (speed 12 knots) Settler (6202 GRT, built 1939), Tanker Svenor (7616 GRT, built 1931) and Tanker Hoegh Hood (9351 GRT, built 1936) These were escorted by the destroyer HMS Encounter (Lt.Cdr. E.V.St J. Morgan, RN) which had been repairing and refitting at Malta.
Through intelligence it was known that the Italian Navy had five battleships operational (three of them at Taranto) and about ten cruisers divided between Taranto, Palermo and Messina. The Italian Air Force had about 50 torpedo planes and 150 bombers (30 of which were dive bombers) stationed in Sardinia and Sicily, roughly half of each type on both islands.
The Royal Air Force was able to be of more help than during the previous convoy trip from Gibraltar to Malta last January. Aircraft from Gibraltar conducted A/S patrols for the fleet during the first two days of the passage to the east. Also patrols were flown between Sardinia and the coast of Africa, while aircraft from Malta conducted reconnaissance between Sardinia and Sicily, besides watching the Italian ports. Malta would also provide fighter escort for Force X and the convoy after Force H would part with them and HMS Ark Royal could no longer provide fighter cover for them.
During the operation eight submarines (HMS Olympus (Lt.Cdr. H.G. Dymott, RN), HMS Unique (Lt. A.F. Collett, RN), HMS Upholder (Lt.Cdr. M.D. Wanklyn, RN), HMS Upright (Lt. J.S. Wraith, DSC, RN), HMS Urge (Lt. E.P. Tomkinson, RN), HMS Utmost (Lt.Cdr. R.D. Cayley, DSO, RN), HMS P 32 (Lt. D.A.B. Abdy, RN) and HrMs O 21 (Lt.Cdr. J.F. van Dulm, RNN)) were on patrol to report and attack Italian warships that might be sailed to intercept the convoy.
The passage East, 22 July 1941
On 22 July the destroyers from Force X oiled from the Brown Ranger two at a time. A task that took about 10 hours. Having completed the oiling of the destroyers the Brown Ranger and her escort returned to Gibraltar. An Italian aircraft had reported Force H in the morning but the convoy and Force X, at that moment about 100 nautical miles to the south-westward, appeared not to have been sighed. At 2317B/22 the Italian submarine Diaspro missed HMS Renown with torpedoes. HMAS Nestor sighted the torpedo tracks and was able to warn HMS Renown which was then able to avoid the torpedoes by doing an emergency turn to port.
The passage East and attacks by the Italian Air Force, 23 July 1941
Force H rejoined the convoy around 0800B/23 as the British were now approaching the danger area. Shadowing aircraft had already reported the position of the fleet that morning and heavy air attacks soon followed.
The first came at 0945 hours, a well times combination of nine high level bombers and six or seven torpedo planes approaching from the north-east. HMS Ark Royal had eleven fighters up, which met the bombers about 20 miles from the fleet. They managed to down two of the nine bombers but unfortunately three Fulmars were shot down by the enemy. The other seven bombers came on working round the head of the screen of destroyers to attack the convoy from the starboard beam at a height of 10000 feet. Their bombs fell harmlessly amongst the leading ships as they altered course to avoid the attack. The torpedo planes however were more successful. They came from ahead out of the sun, flying low, and as the destroyers opened fire they divided into groups of two or three and to attack the convoy on both sides. Two aircraft attacked HMS Fearless, stationed ahead in the screen, dropping their torpedoes at ranges of 1500 and 800 yards from a height of 70 feet. The destroyer avoided the first torpedo, but was hit by the second, set on fire, and completely disabled. Other aircraft went to press on their attacks on the convoy itself. One of them, dropping its torpedo between two merchant vessels hit HMS Manchester as she was turning to regain her station after avoiding two torpedoes fired earlier. She reversed helm once more but to no avail. During the attacks three enemy torpedo bombers were shot down by AA fire from the ships.
HMS Manchester was badly damaged and could only use one engine out of four. At first she could steam only 8 knots. She was ordered to make for Gibraltar with HMS Avon Vale as escort. That evening, further to the westward, they were attacked again by three enemy torpedo planes but their AA gunfire kept the enemy at a distance. Both ships successfully reached Gibraltar on the 26th.
At 1010B/23 five more bombers tried to attack the convoy crossing this time from north to south. Fighters from HMS Ark Royal forced them to drop their bombs from great height and mostly outside the screen.
At 1645B/23 five more torpedo planes led by a seaplane came in from the northward. Three Fulmars caught them about 20 miles away. They managed to shoot down two planes and drove the remainder away.
Soon afterwards the fleet arrived off the entrance to the Skerki Channel. There HMS Hermione was transferred to Force X to take the place of HMS Manchester. Six destroyers were assigned to Force H and eight to Force X. At 1713 hours Vice-Admiral Somerville hauled round to the westward. HMS Ark Royal kept her Fulmars up until RAF Beaufighters had arrived from Malta to take over.
The convoy was attacked again around 1900B/23. Four torpedo planes arrived from the eastward, flying low and and working round from ahead to the starboard side of the convoy. They approached in pairs in line abreast. They kept HMS Sikh (on the starboard bow of the screen) between them and their target until nearly the moment for attack, thereby hampering the AA fire from the other ships. They dropped their torpedoes from long range from a height of 50 feet and nearly hit HMS Hermione, sternmost ship in the starboard column. To avoid the attack each column of the convoy turned 90° outwards and all warships opened barrage fire from all guns that would bear. The barrage however fell short but it caused the Italians to drop their torpedoes early. Also one of the enemy was possibly shot down.
This attack scattered the convoy and it took some time to reform. At 1945B/23 about seven bombers appeared from ahead at a height of about 14000 feet to attack the convoy from the port side. The convoy altered 40° to port together and the escort opened up a controlled fire with some hesitation as the Italian aircraft looked a lot like Beaufighters. The bombing was extremely accurate. Several bombs fell near HMS Edinburgh which was leading the port column, and a near miss abreast a boiler room disabled HMS Firedrake which had been sweeping ahead of the convoy. She could no longer steam so Rear-Admiral Syfret ordered her back to Gibraltar in tow of HMS Eridge. They had an anxious passage, being shadowed by aircraft continuously during daylight hours, but were not again attacked. On the 25th HMS Firedrake managed to lit one boiler so the tow was slipped. Both destroyers entered Gibraltar harbour on the 27th.
Soon after leaving the Skerki Channel in the evening of the 23th the convoy hauled up to the north-east towards the coast of Sicily. This was to lessen the danger of mines. The Italians did not shadow the convoy after the attack at 1945 hours and missed this alteration of course which they clearly did not expect. Around 2100 hours, as it was getting dark, enemy aircraft were seen searching along its old line of advance. During the evening the convoy sighted flares several times about 20 miles to the south.
Continued passage to the east and enemy attacks, 24 July 1941
Between 0250 and 0315 hours the convoy was however attacked by the Italian MAS boats MAS 532 and MAS 533. The managed to torpedo and damaged the Sydney Star. HMAS Nestor went alongside and took off almost 500 soldiers. Sydney Star was however able to continue her passage as staggler escorted initially by HMAS Nestor. Admiral Syfret however sent back HMS Hermione. At 1000B/24 eight German dive bombers and two high level bombers attacked. Their bombs fell close the escorting ships. HMS Hermione shot down one dive bomber. The three ships arrived at Malta early in the afternoon.
The main body of the convoy meanwhile continued on its way unhindered after the attacks of the motor torpedo boats except for an attempt by three torpedo planes around 0700 hours. They dropped their torpedoes at a safe distance when fired on by the destroyers in the screen ahead. According to the orders Rear-Admiral Syfret was to leave the convoy now, if there was no threat from Italian surface forces, and go on to Malta with the cruisers and some of the destroyers. They were to land the passengers and stores, complete with fuel and return to Force H as soon as possible. The remaining destroyers were to accompany the transports to Malta. They too were to join Force H as soon as possible. Rear-Admiral Syfret felt easy about the surface danger as all Italian ships were reported in harbour the day before, but he was anxious about the threat to the convoy from the air. He decided to go ahead with the cruiser but leave all destroyers with the convoy so at 0745B/24, HMS Edinburgh, HMS Arethusa and HMS Manxman left the convoy and pressed ahead at high speed to Malta where they arrived at noon the same day. The transports and the destroyers arrived about four hours later. They had been attacked only once by a torpedo plane since the cruisers separated.
Return passage of the warships of force X to make rendez-vous with Force H.
In the evening HMS Edinburgh, HMS Arethusa, HMS Hermione and HMS Manxman sailed together followed by five destroyers; HMS Cossack, HMS Maori, HMS Sikh, HMAS Nestor, HMS Foxhound, later the same evening. The destroyers overtook the cruisers in the morning of the 25th. The sixth destroyer, HMS Farndale, had to be left at Malta due to defects (condenser problems). All ships made rendez-vous with Force H to the north-west of Galita Island at 0800B/25.
Movements of Force H after it parted from the convoy.
After parting with the convoy in the evening of the 23rd, Vice-Admiral Somerville had taken force H westward at 18 knots until the afternoon of the 24th going as far west as 03°30’E. He then turned back to meet Admiral Syfret, also sending from HMS Ark Royal six Swordfish aircraft which left her in position 37°42’N, 07°17’E at 1000B/25. After their junction Forces H and X made the best of way towards Gibraltar. Fighter patrols of HMS Ark Royal shot down a shadowing aircraft soon after the fleet had shaped course to the westward, losing a Fulmar in doing so. However another aircraft had meanwhile reported the fleet.
High level bombers appeared from the east and torpedo bombers from the north at 1100 hours. HMS Ark Royal at that moment had four fighters in the air and sent up six more. They prevented the bombing attack shooting down three aircraft out of eight at a cost of two Fulmars, while the ships watched the enemy jettison their bombs 15 miles away. The torpedo attack came to nothing too for the enemy gave up the attempt and retired while still several miles from the fleet. Two days later, on the 27th, the fleet reached Gibraltar.
The movements of the seven empty ships coming from Malta.
Six of the transports / tankers left Malta for Gibraltar in the morning of the 23rd, escorted by HMS Encounter. The seventh ship, tanker Svenor grounded while leaving harbour and was held up for some hours. At dusk, when a few miles from Pantelleria, the six ships devided into pairs according to their speed. HMS Encounter initially escorted the middle pair but joined the leading ships in the evening of the 24th when past the Galita Bank.
Italian aircraft, both high level bombers and torpedo planes, attacked all these ships on the 24th to the southward of Sardinia. They made their first attempt on the second pair of transports and HMS Encounter. Four torpedo planes attacked at 1230B/24 and four bombers at 1250B/24. No ships were hit though the bombs fell close. Next came the turn for the leading pair, which were attacked further westwards by two bombers that came singly at 1330B/24 and 1400B/24. The second plane nearly hit HMS Breconshire. Finally when the third pair of ships reached about the same position in the evening they were attacked by torpedo planes and the Hoegh Hood was damaged but she managed to arrive at Gibraltar only a few hours after her consort on the 27th. The last ship, the one that had been delayed at Malta, arrived on the 28th. (23)
22 Jul 1941
At 0435B/22, HMS Unique (Lt. A.F. Collett, RN) dived 10 miles south of the intended patrol position 37°35'N, 15°35'E.
At 1810B/22, in position 37°54'N, 15°35'E faint HE of high speed screws was picked up bearing 060°. It was drawing slowly to the right. Nothing could be seen though. It may have been a motor torpedo boat proceeding close inshore. (16)
23 Jul 1941
At 0915B/23, in position 37°57'N, 15°34'E, HMS Unique (Lt. A.F. Collett, RN) sighted three ships bearing 096° at a range of 9000 yards. Enemy course was 310° at 6 knots. They had not been seen earlier due to the glare of the sun. Course was altered to attack. The convoy consisted of two merchant vessels of about 2000 tons in line ahead with another ship, believed to be an armed merchant cruiser of about 4000 tons. The AMC was inshore of the merchant vessels !
0935B/23, The enemy altered course to 340°.
0948B/23, The convoy was now bearing 078°. Range 5500 yards. Broke off the attack to commence attack on a large vessel seen bearing 016° at a range of 8000 yards. Enemy course was 185°. This vessel was escorted by a torpedo boat.
1000B/23- This new target was now bearing 034° at a range of 3 miles. Enemy course was now 160°. The target was identified as the hospital ship Tevere (Italian, 8448 GRT, built 1913) and the attack was broken off. (16)
24 Jul 1941
At 0320B/24, in position 37°56'N, 15°34'E, HMS Unique (Lt. A.F. Collett, RN) picked up HE bearing 080°.

26 Jul 1941
At 0610B/26, in position 37°57'N, 15°32'E, HMS Unique (Lt. A.F. Collett, RN) sighted a motor torpedo boat bearing 115° at a range of 3 miles. Enemy course was 260° at 18 knots.
At 0749B/26, in position 37°54'N, 15°33'E, a small two-masted schooner (which had also be seen the previous day at at 1410B/25) was seen bearing 240° ar a range of 3 miles. Enemy course was 070°. The schooner was proceeding towards the Italian coast, but returned around 1000B/26 and remained in the vicinity of position 37°55'N, 15°34'E. Later in the afternoon she moved to the vicinity of position 37°54'N, 15°36'E. At dusk she moved off towards the Sicilian coast on course 250°. No fishing gear was observed out and it may well have been an auxiliary A/S vessel.
At 1450B/26, in position 37°58'N, 15°32'E, a Turbine-class destroyer was seen bearing 260° at a range of 4 miles. Enemy course was 030°.
At 1744B/26, in position 37°58'N, 15°34'E, an object was sighted which was believed to be a submarine, bearing 250° at a range of 5 miles. Unique altered course to 320° and closed at speed.
At 1805B/26, the vessel was identified as the Italian submarine chaser Albatros steering 020° at 15 to 18 knots.
At 2100B/26, HMS Unique was ordered to patrol in area 'Q', a rectangle, with it's south-west corner in position 36°40'N, 15°10'E and sides running 350° for 90 miles and 080° for 35 miles. (16)
27 Jul 1941
In the morning, HMS Unique (Lt. A.F. Collett, RN) investigated the Sicilian coast between Taormina and Cape Ali (further north) with a view to carrying out train wrecking operations. (16)
28 Jul 1941
At 1230B/28, in position 37°54'N, 15°24'E, HMS Unique (Lt. A.F. Collett, RN) sighted a small armed yacht bearing 290° at a range of 3 miles. Enemy course was 035°, speed around 6 knots.
At 2130B/28, the Senior Officer Submarines signal timed 1655B/28 was received which stated that HMS Unique may also operate for shore operations in the area originally assigned to HMS Upright (Lt. J.S. Wraith, DSC, RN) as this submarine had now left patrol. (16)
29 Jul 1941
At 0100B/29, HMS Unique (Lt. A.F. Collett, RN) landed a Folbot-party near Cape Ali from a position offshore (38°01'N, 15°27'E) with the objective to place explosive charges on the train tracks. At 0138 hours the Folbot-party (Corporal R.H. Brown and Lance Corporal J.R.A. Ferguson) returned and Unique retired to seaward. At 0325B/29 an explosion was seen on the land as a train must have hit the charges.
According to Italian sources the locomotive and 13 wagons were derailed (some of them carrying German stores) and the engineer was wounded but the line was re-established at noon.
At 0110B/29, during the operation, a 2000 tons merchant vessel was seen bearing 060° at a range of 4 miles. Enemy course was 210° at 10 knots. No attack was made as the target was small and probably in ballast. Also the chances of re-embarking the train wrecking party would have been seriously jeopardised. After the vessel had passed it was seen that she was escorted by a destroyer to seaward.
During the remainder of the day the Calabrian coast to the east of Cape dell'Armi was investigated to carry out another train wrecking operation. At 2335B/29, HMS Unique began to close the coast. (16)
30 Jul 1941
At 0003B/30, HMS Unique (Lt. A.F. Collett, RN) landed a Folbot-party near position 37°55'N, 15°54'E (near Bova Marina) with the objective to place explosive charges on the train tracks. At 0123 hours the Folbot-party returned and Unique retired to seaward. No explosions were seen however before Unique cleared the area. At 0330B/30, the starboard main engine developed a serious defect.
[Nothing was found Italian archives reporting an incident in this area.]
At 1130B/30, in position 37°35'N, 15°45'E a four-masted schooner was sighted bearing 230° at a range of 5 miles. She was laying stopped. She was drifting to leewards and HMS Unique only closed very slowly during the day.
At 1400B/30, the Senior Officer Submarines Malta's signal timed 1123B/30 was received which ordered HMS Unique to resume patrol off the Straits of Messina.
At 1730B/30, it was decided to attack the large schooner. She was of about 500 tons and 130 feet long. She appeared to have a Breda machine gun mounted forward, two amidships and possibly one aft as well. Although laying stopped she did not appear to be fishing. A torpedo fired ran under.
1801B/30 - Fired one torpedo (Mark II) at an armed 4-masted auxiliary patrol schooner in position 37°30'N, 15°35'E from 700 yards. The torpedo ran under. The target hoisted two flags, made a circle and then close Unique's firing position. Another schooner (a smaller two-masted one) joined her and they appeared to be listening. Both departed the area to the south-west at 1850 hours.
At 2000B/30, HMS Unique set course to proceed northwards to comply with the Senior Officer Submarines Malta's signal timed 1123B/30 (see above).
At 2139B/30, the Senior Officer Submarines Malta's signal timed 0335B/30 was received. This started that an enemy submarine would leave Augusta around 2015B/30 on a course of 105°. HMS Unique was at that moment about 20 miles north of the enemy submarine's expected track and with only one main engine operational it was impossible to reach an attack position.
This information was due to ULTRA and referred to the Italian submarine Dessiè which left August at 2000B/30 for Leros. (16)
31 Jul 1941
At 0545B/31, in position 37°43'N, 15°33'E, HMS Unique (Lt. A.F. Collett, RN) sighted a large passenger ship bearing 074° at a range of 8 nautical miles. This ship was identified as the Vichy-French hospital ship Canada (9684 GRT, built 1912) proceeding on course 330° at a speed of 10-12 knots.
At 1120B/31, in position 37°56'N, 15°37'E, a small motor yacht was seen laying stopped. No armament was visible.
At 1328B/31, in position 37°53'N, 15°33'E, a motor torpedo boat (thought to be of the MAS 438-class) was seen bearing 300° at a range of 5 miles. The enemy was moving slowly north, turning later and proceeding slowly southwards. (16)
1 Aug 1941
At 0610B/1, in position 37°57'N, 15°33'E, HMS Unique (Lt. A.F. Collett, RN) sighted a motor torpedo boat bearing 105° at a range of 5 miles. Enemy course was 340° at 8 knots.
At 1005B/1, in position 37°57'N, 15°35'E, a motor torpedo boat was seen bearing 090° at a range of 2 miles. She was laying stopped. She proceeded at 1058B/1 on course 220° at 20 knots. HMS Unique altered course away to evade but two minutes later the enemy stopped again.
At 1115B/1, the enemy was bearing 120° at 1000 yards. HMS Unique went to 70 feet and ran out to the south-west.
At 1300B/1, HMS Unique returned to periscope depth. The motor torpedo boat was seen bearing 020° at a range of 2 miles. A fishing boat, flying a red flag was seen bearing 350° at a range of 2 miles. Both were laying stopped. HMS Unique retired to the south.
At 1306B/1, the Senior Officer Submarines signal timed 1044B/1, was received ordering HMS Unique to stay on patrol until 2100B/2 to intercept a cruiser and a tanker bound from Messina to Crete.
At 2115B/1, HMS Unique surfaced and sighted three large ships, all well lit, bearing 320° at a range of 5 miles. Their course was 160° at 12 knots. These were identified as three Vichy-French ships on which orders had been received not to molest them (Senior Officer Submarines Malta's signal timed 1057B/31). They were led by a darkened motor torpedo boat which turned back toward Messina half an hour later. (16)
2 Aug 1941
At 0217B/2, in position 37°48'N, 15°48'E, HMS Unique (Lt. A.F. Collett, RN) heard the noise of a fast revving engine, fairly loud which passed down the starboard side from west to east. Visibility was just over 2 miles. Nothing was sighted an no HE was heard.
At 0335B/2, in position 37°49'N, 15°52'E, ships were sighted bearing 025° at a range of about 4 miles. Enemy course was 270° at about 10 knots. The vessels were difficult to distinguish in the poor visibility and against the land but they appeared to be a 3000 tons merchant vessel and two smaller merchant vessels escorted by two destroyers or torpedo boats. HMS Unique closed at 6 knots but it was decided not to attack in order to not give away the submarines position as the expected cruisers and tanker mentioned in the Senior Officer Submarines signal timed 1044B/1 had not yet been sighted. HMS Unique dived to avoid being sighted.
At 1303B/2, in position 37°51'N, 15°53'E, sighted two destroyers bearing 075° at a range of 4 miles. Enemy course was 270°. HMS Unique altered course to keep clear and went deep.
At 1400B/2, on returned to periscope depth one destroyer was sighted bearing 310° at a range of 4 miles. Enemy course was 090°. A Cant. Z 501 flying boat was flying very low from the direction of the destroyer straight towards HMS Unique which quickly went deep again.
At 1450B/2, HMS Unique returned to periscope depth. There was nothing in sight.
At 2100B/2, HMS Unique left patrol and set course for Malta. (16)
4 Aug 1941
Around 0700B/4, HMS Unique (Lt. A.F. Collett, RN) ended her 12th war patrol (10th in the Mediterranean) at Malta. (16)
8 Aug 1941
HMS Unique (Lt. A.F. Collett, RN) is docked in No.2 graving dock at the Malta Dockyard. (24)
13 Aug 1941
HMS Unique (Lt. A.F. Collett, RN) is undocked. (24)
16 Aug 1941
Around 1830B/16, HMS Unique (Lt. A.R. Hezlet, RN) departed Malta for her 13th war patrol (11th in the Mediterranean). She was ordered to patrol off Tripoli, Libya in 'Area T' (south of 33°20'N, and between 11°40'E and 13°10'E).
Lt. Hezlet had taken over from Lt. Collett for this patrol in order to give Lt. Collett a rest.
On departure for patrol a practice attack was made on HMS Abingdon (Lt. G.A. Simmers, RNR). (25)
16 Aug 1941
For the daily and attack positions of HMS Unique during her 13th war patrol see the map below.
18 Aug 1941
Around 0500B/18, HMS Unique (Lt. A.R. Hezlet, RN) arrived in position 33°20'N, 13°10'E (to the north of Tripoli) to intercept a 8.5 knot convoy expected at Tripoli around 1630B/18.
This referred to a convoy from Naples to Tripoli which was made up of the transports Caffaro (Italian, 6476 GRT, built 1924), Giulia (Italian, 5921 GRT, built 1926), Maddalena Odero (Italian, 5545 GRT, built 1921), Marin Sanudo (Italian, 5958 GRT, built 1926), Nicolò Odero (Italian, 6003 GRT, built 1925) and the tanker Minatitland (Italian, 7651 GRT, built 1941). It was escorted by the Italian destroyers Freccia, Euro, Dardo and the Italian torpedo boats Procione and Pegaso. The torpedo boat Giuseppe Sirtori sailed from Palermo at 1600B/16 to reinforce the escort. Off Trapani, Procione was detached and entered this port at 1300B/28. Eight miles south of Lampedusa, Maddalena Odero was torpedoed twice by RAF bombers at 2045B /17. Pegaso towed her to Lampedusa while Sirtori looked for survivors. Giuseppe Sirtori, Pegaso and the stricken vessel entered this port at 1215B/18 (or 1020B/18, sources give diffent times). At 1300B/18, Maddalena Odero was hit by a bomb from a RAF aircraft and blew up. Pegaso turned back, arriving at Trapani at 0625B/19, while Giuseppe Sirtori sailed from Lampedusa at 2015B/18 for Porto Empedocle. The remainder of the convoy reached Tripoli at 1700B/18-1800B/18.
The convoy had been attacked in position 39°35'N, 13°18'E by HrMs O 23 (Lt.Cdr. G.B.M. van Erkel, RNN) at 1004A/16 (1115B/16 according to the Italians) from long range but all torpedoes missed. The torpedoes were sighted by Freccia and by a CANT Z.501 seaplane.
Between 0650B/18 and 0700B/18, HMS Unique called HMS P 33 (Lt. R.D. Whiteway-Wilkinson, DSC, RN) on S.S/T. There was no reply.
At 0810B/18, HMS P 33 was called again on S.S/T but yet again no reply was forthcoming.
At 0820B/18, when in position 33°19'30"N, 13°10'30"E, S.S/T communication was established with HMS P 32 (Lt. D.A. Abdy, RN) which bore 180° at 180 miles.
Between 0930B/18 amd 1330B/18 distant explosions were heard approaching. The convoy was coming !
At 1459B/18, the Senior Officer Submarines Malta's signal timed 1401B/18 was received which ordered HMS Unique to proceed with despatch to position 33°00'N, 13°03'E. At 1216B/18 the convoy had been in position 306° - Tripoli - 56 miles, course 130° at 8 knots.
At 1517B/18, As the convoy could not be intercepted submerged HMS Unique surfaced and set course 194° at full speed.
At 1534B/18, three aircraft were seen patrolling ahead as though escorting a convoy. As they were about 10 miles away, continued to close on the surface.
At 1600B/18, a schooner was sighted laying stopped 8 miles on the starboard bow.
At 1617B/18, HMS Unique dived for a large aircraft flying very low and towards. Continued to close the ordered position at 5 knots submerged.
At 2115B/18, HMS Unique surfaced and withdrew to the north-west along approach route of convoy. (16)
19 Aug 1941
Around 0800B/19, HMS Unique (Lt. A.R. Hezlet, RN) commenced patrolling in the vicinity of position 33°20'N, 13°03'E in accordance with the Senior Officers Submarines Malta's signal timed 1101B/18 to intercept a fast, 17.5 knot, convoy which was due at Tripoli at noon on 20 August. [For the composition of this convoy see the event for 20 August 1941.]
At 0920B/19, HMS P 32 (Lt. D.A.B. Abdy, RN) was called on S.S/T. There was no reply.
At 1547B/19, distant explosions at 15 minute intervals were heard to the westwards. Altered course to 270°.
At 1655B/19, masts and funnels of four merchant vessels were seen bearing 275° at a range of about 10 miles. Enemy course was 345°, speed about 10 knots. A single mast, thought to have been from a destroyer, was seen ahead of the convoy. A flying boat was circling the convoy.
This convoy was made up of the transports Andrea Gritti (Italian, 6338 GRT, built 1939), Francesco Barbaro (Italian, 6343 GRT, built 1940), Rialto (Italian, 6099 GRT, built 1927), Sebastiano Venier (Italian, 6311 GRT, built 1940) and Vettor Pisani (Italian, 6339 GRT, built 1939). They were escorted by the Italian destroyers Freccia, Euro, Dardo and the Italian torpedo boat Procione. The convoy sailed from Tripoli at 1245B/9-1345B/19 and arrived at Naples at 0800B/21-0945B/21 (except Procione who arrived at 1610B/21).

20 Aug 1941
HMS Unique (Lt. A.R. Hezlet, RN) torpedoed and sank the Italian liner / troop transport Esperia (11398 GRT, built 1920) 11 nautical miles bearing 318° of the Tripoli lighthouse, Libya in position 33°03'N, 13°03'E.
Esperia had been in convoy that was further made up of the Italian liners / troop tranports Marco Polo (12272 GRT, built 1912), Neptunia (19328 GRT, built 1932) and Oceania (19507 GRT, built 1933). They were escorted by the Italian destroyers Ugolino Vivaldi, Nicoloso Da Recco, Vincenzo Gioberti and Alfredo Oriani. The convoy had sailed from Naples at 2255B/18- 0140B/19 for Tripoli. The escort was reinforced by the destroyers Maestrale, Grecale (both until 0100B/20) and Scirocco who sailed from Palermo at 0730B/19 (except Grecale who followed at 0325B/20) and the torpedo boat Giuseppe Dezza who sailed from Trapani at 0925B/19. The torpedo boat Partenope had sailed from Tripoli at 0620B/20 to reinforce the escort. The convoy, minus Esperia arrived at Tripoli at 1245B/20-1415B/20.
According to Italian sources four were killed and twelve were missing, 1139 survivors (including 53 wounded) were picked up.
0636B/20 to 0725B/20 - Sighted the torpedo boat Partenope, two MAS boats and three minesweepers. They were passing about a mile inshore of Unique. From their movements the position of the swept channel was fixed and Unique was placed near the entrance to await the convoy of troopships that was reported.
0956B/20 - In position 33°03'N, 13°03'E sighted four liners bearing 305°, range about 8 nautical miles. Enemy course was 155°. Started attack.
1010B/20 - Range was now 6500 yards. Of the escort a Partenope-class torpedo boat was sighted an also a Navigatori-class destroyer but most likely there were many others.
1019B/20 - After getting inside the escort screen fired a salvo of four torpedoes from 650 yards against one of the liners. Upon firing Unique cleared the torpedo tracks and set course to the north at 90 feet. Shortly afterwards three torpedoes were heard to hit the target.
1037B/20 to 1137B/20 - 15 Depth charges were dropped but none were close.
1230B/20 - Came to periscope depth, only a fling boat and a schooner were seen. Went deep again and reloaded the torpedo tubes.
1620B/20 - Called HMS P 32 (Lt. D.A.B. Abdy, RN) on S.S/T. There was no reply.
1815B/20 - While at periscope depth in position 33°13'N, 12°56'E sighted a CANT Z-501 flying boat alter towards. Went deep and altered course.
1816B/20 - A depth charge exploded on the port quarter.
1818B/20 - Another depth charge exploded very close on the port beam. Some minor damage was caused. Went to 150 feet.
According to Italian sources the aircraft was a CANT Z.501 of 145^ Squadriglia piloted by Midshipman De Solem who dropped two bombs and claimed to have hit the submarine. (16)
21 Aug 1941
HMS Unique (Lt. A.R. Hezlet, RN) was patrolling off Zuara parallel to the coastal shipping route.
At 1317B/21, the Senior Officer Submarines Malta's signal timed 1231B/21 was received ordering HMS Unique to intercept the 17 knot convoy leaving Tripoli at 1700B/21. It was not possible to reach position 33°07'N, 13°07'E as ordered in time but position 33°14'N, 12°47'E covering the route along which the convoy arrived yesterday and the route from position 32°53'N, 12°53'E to Kerkennah could be reached by proceeding on the surface at full speed for two hours. So Unique surfaced at 1340B/21 and ran to the north-east at full speed.
The signal referred to the Italian liners / troop transports Marco Polo (12272 GRT, built 1912), Neptunia (19328 GRT, built 1932) and Oceania (19507 GRT, built 1933) and their escort made up of the Italian destroyers Ugolino Vivaldi, Nicoloso Da Recco, Alfredo Oriani and Scirocco (the last one until Palermo only). The convoy was to proceed from Tripoli to Naples.
At 1440B/21, HMS Unique had to dive for an aircraft but was apparently not sighted.
At 1510B/21, HMS Unique had just surfaced when it was noticed that the submarine was leaving an oil slick.
At 1600B/21, HMS Unique dived and proceeded further to the north-east while submerged.
At 1857B/21, A Generali-class torpedo boat was seen 5 miles to the eastward proceeding towards Tripoli.
At 2015B/21, HMS Unique was at periscope depth when an explosion was heard. A thin column of water was sighted about one mile away through the periscope. This was repeated four times. It appeared that Unique was bombed from the air although no aircraft were sighted. Two minutes later, HE was heard and fire was opened on the periscope with a gun. Unique was taken to 90 feet and course was altered. For the next 45 minutes HMS Unique was hunted but no depth charges were dropped.
At 2250B/21, HMS Unique surfaced and withdrew to the northward to investigate the oil leak. (16)
22 Aug 1941
At 0700B/22, HMS Unique (Lt. A.R. Hezlet, RN) left patrol to return to Malta. The oil leak was still present giving away the presence of the submarine.
At 2256B/22, a W/T report was passed informing Malta of their return. (16)
23 Aug 1941
Around 1900B/23, HMS Unique (Lt. A.R. Hezlet, RN) ended her 13th war patrol (11th in the Mediterranean) at Malta. (16)
25 Aug 1941
HMS Unique (Lt. A.F. Collett, RN) is docked in No.2 graving dock at the Malta Dockyard. (24)
1 Sep 1941
HMS Unique (Lt. A.F. Collett, RN) is undocked. (26)
5 Sep 1941
Around 1500B/5, HMS Unique (Lt. A.F. Collett, RN) departed Malta for her 14th war patrol (12th in the Mediterranean). She was ordered to patrol in the Tyrrhenian Sea.
On departure two practice attacks were made on HMS Gloxinia (Lt.Cdr. A.J.C. Pomeroy, RNVR). (27)
5 Sep 1941
For the daily positions of HMS Unique during her 14th war patrol see the map below.
6 Sep 1941
At 2136B/6, HMS Unique (Lt. A.F. Collett, RN) received Capt. S. 10's signal timed 1210B/6 reporting a northbound convoy due at Marittimo at 0430B/7.
This referred to the convoy made up of the Italian transports Col di Lana (5891 GRT, built 1926), Ernesto (7399 GRT, built 1914) and the Italian tanker Poza Rica (7799 GRT, built 1940). They were on passage from Tripoli to Naples. The convoy was escorted by the Italian destroyers Nicoloso Da Recco, Freccia, Folgore and Strale.
At 2330B/6, HMS Unique altered course to the north-east along the Cape Bon to Naples convoy route. (28)
7 Sep 1941
At 0540B/7, HMS Unique (Lt. A.F. Collett, RN) dived and patrolled in the vicinity of position 'L' (north of Marittimo, 38°16'N, 12°08'E) during the day.
At 2035B/7, HMS Unique surfaced and set course for Cape St. Vito. (16)
8 Sep 1941
At 0540B/8, HMS Unique (Lt. A.F. Collett, RN) dived 8 miles north of Cape St. Vito which was then closed after HMS Unique patrolled eastwards along the coastal route.
At 1035B/8, just north of Cape St. Vito, in position 38°14'N, 12°43'E, a trawler and two fishing boats were seen bearing 210 at a range of 4 miles. Enemy course was approximately 360°. These vessels proceeded slowly up the coastal route. It was thought this may be auxiliary A/S vessels.
At 1200B/8, HMS Unique went to 80 feet and ran out to the northward to evade the above vessels as they were now approaching.
At 1255B/8, now in position 38°16'N, 12°47'E, HMS Unique returned to periscope depth. The vessels had apparently passed since smoke could be seen along the coastal route to the eastward. A three-masted schooner with an auxiliary engine was seen bearing 195° at a range of 2 miles. Enemy course was 245°.
At 1837B/8, in position 38°16'N, 12°58'E, a destroyer and two small merchant vessels were seen bearing 262° at a range of 6 miles. Enemy course was 085°. The destroyer, thought to be a Maestrale-class, was making very wide zigzags across the bows of the two merchant vessels which were in line ahead on a steady course and making good about 6 knots.
At 1926B/8, both merchant vessels were seen to be of 1500 tons or less and in ballast. It was therefore decided that they were not worth a torpedo and the approach was broken off.
At 2025B/8, HMS Unique surfaced and set course to the eastward. (16)
9 Sep 1941
At 0058B/9, HMS Unique (Lt. A.F. Collett, RN) received the Capt. S. 10's signal timed 0030B/9 which reported that a 8.5 knot southbound convoy five merchant ships and six destroyers from Naples was expected at Marittimo around 0400B/10.
This must have referred to the convoy made up of the transports Bainsizza (Italian, 7933 GRT, built 1930), Caffaro (Italian, 6476 GRT, built 1924), Giulia (Italian, 5921 GRT, built 1926), Nicolò Odero (Italian, 6003 GRT, built 1925), Nirvo (Italian, 5270 GRT, built 1919) and Tembien (Italian, 5584 GRT, built 1914) and their escort made up of the Italian destroyers Alfredo Oriani, Fulmine and the torpedo boats Procione, Pegaso and Orsa. The convoy however appears to have been delayed as they only sailed from Naples for Tripoli around 1030B/10.
At 0115B/9, course was altered to the westward to intercept.
At 0545B/9, HMS Unique dived.
At 1137B/9, north of Cape St. Vito, in position 38°16'N, 12°47'E, a small merchant vessel and a fishing boat were seen bearing 210° at a range of 4 miles. Enemy course was 265°. Course was altered to close.
At 1200B/9, the attack was broken off as the merchant vessel was considered too small to attack from long range.
At 2040B/9, Unique surfaced and continued her passage to the Marittimo area. (16)
10 Sep 1941
HMS Unique (Lt. A.F. Collett, RN) commenced patrolling near position 'L' (38°16'N, 12°08'E). She kept down moon of the expected line of advance of the convoy.
At 0540B/10, HMS Unique dived.
At 2030B/10, HMS Unique surfaced. Nothing had been seen all day. (16)
11 Sep 1941
At 0008B/11, north of Cape St. Vito, in position 38°16'N, 12°30'E, HMS Unique (Lt. A.F. Collett, RN) sighted smoke bearing 115° moving right. Course was altered to 160° to intercept on the coastal route. The target mover rapidly right and as HMS Unique was then 10 miles from the coastal route the chase was given up as the situation was hopeless.
At 0158B/11, in position 38°17'N, 12°52'E, a dark object was sighted bearing 135° at a range of 7000 yards. This was thought to be a submarine and course was altered and an attack was started.
At 0202B/11, the target was identified as being a trawler moving very slowly westwards along the coast. The attack was broken off.
At 0540B/11, HMS Unique dived and patrolled on the coastal route near Palermo.
At 0815B/11, north of Palermo, in position 38°15'N, 13°25'E, three fishing vessels were seen bearing 150° at a range of 3 miles. They were presumed to be auxiliary minesweepers. They were in line abreast and were all flying two back balls and a large flag.
At 0830B/11, the minesweepers altered course to 290°.
At 1120B/11, the minesweepers rounded Cape Gallo and disappeared to the westward.
At 1430B/11, in position 38°12'N, 13°35'E, three fishing vessels were seen bearing 180° at a range of 4 miles. They were flying the usual signals and were apparently mine sweeping on course 170°. They later turned to 360°.
At 2025B/11, HMS Unique surfaced and set course to the north-eastward. (16)
12 Sep 1941
At 0540B/12, HMS Unique (Lt. A.F. Collett, RN) dived and patrolled eastwards along the presumed convoy route north of Stromboli running 075° from position 'L' (north of Marittimo, 38°16'N, 12°08'E).
At 2020B/12, HMS Unique surfaced. Nothing had been sighted while patrolling submerged.
At 2315B/12, HMS Unique turned north-west along the direct route from Cape Vaticano to Naples an which route she patrolled on the 13th. Nothing was seen though. (16)
14 Sep 1941
At 0540B/14, HMS Unique (Lt. A.F. Collett, RN) dived 10 miles to the south of Capri Island.
At 0625B/14, on coming to periscope depth 20 minutes before sunrise in position 40°24'N, 14°15'E, an Oceania-class liner escorted by two detroyers was sighted bearing 090° at a range of 7 miles. Enemy course was 160°. From her position and course it appeared that she had come through the Bocca Piccola. Unique now set course to patrol to the south of the Bocca Piccola.
At 0710B/14, a barquentine proceeding under the power of an auxiliary engine was seen bearing 295° at a range of 3 miles. Enemy course was 090°. Unique altered course to 180° to avoid. The barquentine, thought to be an auxiliary A/S vessel, later moved off the the south-west.
At 1110B/14, in position 40°27'N, 14°20'E, three fishing boats flying black balls and large flags were seen bearing 350° at ranges between 7 - 8 miles. They appeared to be sweeping westwards just to the north of the Bocca Piccola.
At 1330B/14, in position 40°28'N, 14°23'E, a 3000 tons merchant vessel was seen bearing 335° at a range of 10 miles. Enemy course was 050° at 12 knots.
At 1355B/14, in position 40°28'N, 14°22'E, a small coaster was sighted bearing 008° at a range of 6.5 nautical miles. Enemy course was 105°.
At 1940B/14, in position 40°27'N, 14°24'E, two big merchant vessels and one small ship were seen bearing 260° at a range of about 7 miles. They were extremely difficult to observe in the dusk but were moving northward and course was probably 330°. This would have taken them to the west of Capri and not through the Bocca Piccola.
At 2025B/14, HMS Unique surfaced and set course to patrol on the original suspected convoy route, 147° from close west of Capri Island. (16)
15 Sep 1941
At 0135B/15, south-west of Capri Island, in position 40°27'N, 14°09'E, HMS Unique (Lt. A.F. Collett, RN) picked up HE of 150 revs bearing 035°. One minute later a destroyer was seen bearing 040° at a range of 4 miles. Enemy course was 160° at 15 knots.
At 0535B/15, HMS Unique dived 4 miles to the east of Capri Island.
At 0618B/15, in position 40°32'N, 14°08'E, HE was picked up on bearing 190°.
At 0621B/15, a convoy was sighted bearing 190° at a range of 7 miles. Enemy course was 045° at 14 knots. The convoy consisted of two merchant vessels of about 10000 tons and one of about 6000 tons. They were escorted by five destroyers. A Cant Z.501 flying boat was patrolling overhead. Commenced attack.
This must have been the convoy made up of the transports Rialto (Italian, 6099 GRT, built 1927), Sebastiano Venier (Italian, 6311 GRT, built 1940) and Vettor Pisani (Italian, 6339 GRT, built 1939) escorted by the italian destroyers Alfredo Oriani, Fulmine and the torpedo boats Procione, Pegaso and Orsa which had come from Tripoli.
It was however not possible to get into firing range before the convoy passed through the Bocca Piccola and the attack was broken off at 0700B/15. HMS Unique now set course to patrol just to the eastward of the approach route to the Bocca Piccola.
At 0852B/15, in position 40°29'N, 14°13'E, two merchant vessels were seen bearing 080° at a range of 7 miles. Enemy course was 305° at 7 knots. The merchant vessels were of 1500 and 2500 tons. These ships were also heading for the Bocca Piccola. They could not be closed sufficiently to attack.
At 1040B/15, in position 40°29'N, 14°15'E, three minesweepers were seen bearing 045° at a range of 5 miles. Enemy course was 150°. They swept up and down four times between the Bocca Piccola and position 40°29'N, 14°23'E before returning to harbour.
At 1110B/15, a 3-masted sailing vessel was seen bearing 225° at a range of 8 miles. It was laying stopped remaining in the vicinity of this position all day. Obviously an auxiliary A/S vessel.
At 1257B/15, in position in position 40°27'N, 14°18'E, HMS Unique had just come to periscope depth, when an Italian submarine of the Adua-class was sighted bearing 310°, steering 185°, apparently exercising with a 'Generale'-class destroyer / torpedo-boat. This was almost certainly the Italian submarine Corallo exercising at the time with the torpedo-boat Generale Antonio Cascino.
HMS Unique was unable to gain an attacking position and was thwarted by the presence of the destroyer / torpedo-boat. Later a trawler was also seen with the submarine and destroyer / torpedo boat. An attack had not been possible to the erratic movements of the ships during the exercises.
At 1746B/15, in position 40°29'N, 14°15'N, a motor torpedo boat was seen bearing 008° at a range of 2 miles. She was laying stopped, probably listening. Course was altered away to the southward.
At 2025B/15, HMS Unique surfaced and set course to position 'L''(north of Marittimo, 38°16'N, 12°08'E). She proceeded along the expected convoy route but nothing was seen on the 16th. (29)
17 Sep 1941
At 0605B/17, HMS Unique (Lt. A.F. Collett, RN) dived 12 miles to the north of Marittimo Island and then patrolled close westward of that island. She surfaced at 2025B/17. Nothing had been seen all day. (16)
18 Sep 1941
At 0001B/18, HMS Unique (Lt. A.F. Collett, RN) left patrol to return to Malta.
At 0512B/18, south-west of Marsala, in position 37°41'N, 12°12'E, HMS Unique sighted two merchant vessels and two destroyers bearing 060° at a range of 4 miles. Both ships were about 2000 to 3000 tons and were not more than half laden. They were zigzagging 30° either side of a mean course of 210°. The destroyers were zigzagging about 50° on either side of this course at 15 knots.
At 0520B/18, HMS Unique was 2000 yards ahead of the other wing destroyer and dived as it was too light from the approaching dawn to continue the attack on the surface. The destroyer could not be observed through the periscope due to a bad horizon and the HE was reported all round, HMS Unique was forced to go deep. The convoy passed close down the port side (500 to 1000 yards) and the destroyer passed very close astern probably only at 100 yards. On return to periscope depth the rear merchant vessel was seen at a range of 3000 yards on a 160° track and the attack had to be abandoned. (16)
19 Sep 1941
Around 0930B/19, HMS Unique (Lt. A.F. Collett, RN) ended her 14th war patrol (12th in the Mediterranean) at Malta. It had been a most frustrating patrol with quite a lot of sightings but no opportunities for attack. (16)
5 Oct 1941
HMS Unique (Lt. A.F. Collett, RN) is docked in No.2 graving dock at the Malta Dockyard. (30)
7 Oct 1941
HMS Unique (Lt. A.F. Collett, RN) is undocked. (30)
9 Oct 1941
Around 1300A/9, HMS Unique (Lt. A.F. Collett, RN) departed Malta for her 15th war patrol (13th in the Mediterranean). She was ordered to a position south-east of Cape Bon, Tunisia (36°35'N, 11°28'E) to intercept a southbound convoy. As the convoy passed well to the east, Unique was later ordered to her patrol area in the Tyrrhenian Sea.
The convoy referred to must have been the one made up of the transports Bainsizza (Italian, 7933 GRT, built 1930), Casaregis (Italian, 6485 GRT, built 1924), Giulia (Italian, 5921 GRT, built 1926), Nirvo (Italian, 5270 GRT, built 1919), Zena (Italian, 5219 GRT, built 1914) and the tanker Proserpina (Italian, 4870 GRT, built 1926). It was escorted by the destroyers Granatiere, Fuciliere, Bersagliere and Alpino and was on passage from Naples to Tripoli.
For the daily and attack positions of HMS Unique during this patrol see the map below.
(16)
10 Oct 1941
At 0030A/10, HMS Unique (Lt. A.F. Collett, RN) altered course to close the convoy's mean line of advance at right angles, with the intention of diving on the line before dawn.
At 0441A/10, south of Pantelleria, in position 36°06'N, 11°55'E, a destroyer was sighted bearing 135° at a range of 3 miles. Enemy course was 350° at 12 knots. HMS Unique dived since the moon was bright. Faint HE was heard and the destroyer was heard to pass to the eastward.
At 1120A/10, south-west of Pantelleria, in position 36°14'N, 11°40'E, a faint wisp of smoke was seen bearing 070°. This was probably the expected convoy which as later reports showed had passed about 12 miles to the eastward.
At 1632A/10, Capt. S.10's signal timed 1524A/10 was received which ordered HMS Unique to proceed in execution with her originally intended patrol orders, to patrol in the Tyrrhenian Sea. Course was set to pass to the eastward of Pantelleria and then dive to pass through the Italian minefield off south-west Sicily during daylight on the 11th. (16)
11 Oct 1941
At 0900A/11, in position 37°28'N, 12°22'E, HMS Unique (Lt. A.F. Collett, RN) picked up faint HE (90 revs) bearing 280°. The HE was moving south. Ten minutes later HMS Unique was at periscope depth but nothing could be seen.
At 0935A/11, more faint HE was heard on bearing 290°. It was also moving south. (16)
12 Oct 1941
At 0503A/12, HMS Unique (Lt. A.F. Collett, RN) dived and then patrolled the coastal route north-east of Cape St. Vito.
At 0817A/12, north of Cape St. Vito, in position 38°15'N, 12°46'E, a Navigatori-class destroyer was sighted bearing 300° at a range of only one mile. Enemy course was 230° at 18 knots. Unique went to 80 feet and took avoiding action. Ten minutes later HE had faded but at 0830A/12 two depth charges were heard exploding, a long way off though.
At 1855A/12, HMS Unique surfaced and set course for Naples. (16)
14 Oct 1941
HMS Unique (Lt. A.F. Collett, RN) made a torpedo attack on an Italian armed merchant cruiser south of Naples Bay. A torpedo hit is claimed as the ship stopped and appeared to be damaged.
This was the armed merchant cruiser Adriatico (1976 GRT, built 1931) escorting the water tanker Cassala (1771 GRT, built 1902) from Naples to Messina. All four torpedoes missed. One was avoided by the Adriatico and two by the Cassala. The torpedo boat Giuseppe Missori and the 3rd A/S Group were ordered to hunt the submarine but found nothing.
0900A/14 - Entered area 'N' (north of 40°00'N, 14°15'E).
1210A/14 - While to the south of the Bocca Piccola, in position 40°26'N, 14°20'E sighted smoke bearing 350° in the Gulf of Naples.
1236A/14 - Sighted two merchant vessels bearing 335°. Range was about 8 nautical miles. They were altering course to pass south through Bocca Piccolo. Unique altered course to attack. The leading ship was identified as a Citta di Genova-class or Birmania-class. The ship was painted white and was most likely an armed merchant cruiser. The second ship was a 'funnel-aft' merchant vessel of about 5000 tons in ballast.
1314A/14 - Fired four torpedoes from 3500 yards.
1330A/14 - Observed the AMC stopped with a black streak down her starboard side. It appears she was hit. The merchant vessel meanwhile had turned round and was making back to Naples. Unique went deep again and retired to the south-east.
1337A/14 - Heard an explosion, which was not considered to be a depth charge. It is claimed a hit had been obtained and the target was damaged. Unique was now at 130 feet and rand out to the south and then the east.
1445A/14 - Very distant depth charging was heard. They were dropped at 10 minute intervals until 1540A/14.
1640A/14 - Returned to periscope depth. There was nothing in sight.
1645A/14 - Went to 80 feet and commenced reloading the torpedo tubes.
1702A/14 - Three distant depth charges were dropped.
1853A/14 - On coming to 40 feet before surfacing in position 40°19'N, 14°12'E fairly loud HE (170 revs) was picked up bearing 050°. It was drawing right to 085° but then drawed left.
1922A/14 - HE faded out on bearing 025°.
1926A/14 - Surfaced.
1936A/14 - Sighted a dark object bearing 135° at a range of about one mile. It was moving northwards and is thought to have been a motor torpedo boat.
1937A/14 - Dived to avoid being sighted. No HE was picked up.
2112A/14 - Surfaced.
2115A/14 - Heard faint HE (160 revs) bearing 100°. It was drawing north. Nothing could be sighted though.
2359A/14 - Set course for Licosa Point to patrol on the coastal route between Messina and Naples the following day.
Lt. Collett was later criticised by Capt. S.10 for this action as he should have reloaded one torpedo tube very quickly to finish off the damaged ship. (16)
15 Oct 1941
At 0203A/15, in position 40°11'N, 14°12'E, HMS Unique (Lt. A.F. Collett, RN) sighted a destroyer bearing 140° at a range of 4 miles. Enemy course was 320°. HMS Unique altered course away. This may have well been the torpedo boat Giuseppe Missori which was on an A/S hunt in the area following yesterdays attack by HMS Unique.
At 0205A/15, the destroyer altered course to 270°.
At 0208A/15, HMS Unique dived to avoid being sighted.
At 0212A/15, HE (160 revs) faded out on bearing 250°.
At 0400A/15, HMS Unique surfaced.
At 0424A/15, in position 40°12'N, 14°20'E, a destroyer was sighted bearing 350° at a range of 5 miles. Enemy course was 190°.
At 0426A/15, HMS Unique again dived to avoid being sighted.
At 0520A/15, in position 40°13'N, 14°21'E, HE (170 revs) was picked up bearing 230°. It was moving slowly left.
At 0555A/15, HE was still audible on bearing 120°. On coming to periscope depth a Navigatori-class destroyer was sighted bearing 104° at a range of 3 miles. The enemy was steering to the north-west. This was probably still the torpedo boat Giuseppe Missori though. [This was a ship with three funnels but the forward funnel was very close to the forward superstructure so Lt. Collect probably saw only two funnels which was the same number as the Navigatori-class destroyers had.]
At 0600A/15, HMS Unique was at 60 feet. The destroyer moved slowly left down the port side.
At 0640A/15, HE faded out on bearing 350° which was the direction of the Bocca Piccolo.
At 0650A/15, in position 40°13'N, 14°23'E, two masts of a small sailing vessel were seen bearing 294°. Range was 7 miles. The enemy was moving slowly backwards and forwards. This was most likely one of the auxiliary A/S schooners operating off Naples Bay.
At 1400A/15, course was altered to the south-east parallel to the coastal route. (16)
16 Oct 1941
At 0505A/16, HMS Unique (Lt. A.F. Collett, RN) dived and commenced to patrol parallel to and to seaward of the coastal route between Licosa Point and Cape Palinuro.
At 0740A/16, in position 40°02'N, 15°08'E, a small minelayer / minesweeper (Crotone-class or RD-class) and a fishing boat were seen bearing 030° at a range of 3 miles. Enemy course was 310° at 9 knots.
At 1845A/16, HMS Unique surfaced.
At 1946A/16, in position 40°10'N, 14°45'E, a destroyer was sighted bearing 310° at a range of 3 miles. Enemy course was 110°.
At 1948A/16, HMS Unique dived to avoid being sighted. Seven minutes later the destroyer passed close ahead of HMS Unique doing 230 revs. HE later faded out on bearing 140°.
At 2120A/16, HMS Unique surfaced. (16)
17 Oct 1941
At 0005A/17, after having completed charging, HMS Unique (Lt. A.F. Collett, RN) closed the Capri - Licosa coastal route and proceeded to the north-west along it.
At 0450A/17, in position 40°30'N, 14°27'E a destroyer was sighted bearing 250° at a range of 6 miles. Enemy course was 030°.
At 0500A/17, HMS Unique dived.
At 0555A/17, in position 40°30'N, 14°24'E, a two-masted sailing vessel was seen. This vessel was moving slowly backwards and forwards and thus could very well be an auxiliary A/S vessels.
From 0837A/17 to 0900A/17, a regular ticking noise was heard on bearing 250°. Nothing was in sight on this bearing.
From 0920A/17 to 0955A/17, the ticking noise was heard again on bearing 270°. Again nothing could be sighted.
At 1656A/17, south-south-east of the Bocca Piccola, in position 40°20'N, 14°27'E, a large merchant vessel was seen bearing 257° at a range of 21000 yards. Enemy course was 160°. Only her funnel and masts were seen so ant escort would have been visible.
At 1855A/17, HMS Unique surfaced and then set course to return to Malta leaving patrol. She was to proceed through position 38°40'N, 11°50'E (north-north-west of Marittimo) in accordance with Capt. S.10's signal timed 1255A/15. (16)

[No enemy submarine is known to have been in this area.] (19)
5 Nov 1941
At 1800B/5, HMS Unique (Lt. A.F. Collett, RN) entered area
'C' in position 32°45'N, 18°15'E. (19)
6 Nov 1941

At 1640B/6, HMS Unique withdrew 5 miles to the north-westward.
At 1820B/6, HMS Unique surfaced and patrolled in the vicinity of position 32°41'N, 20°03'E until 0600B/7 with the view of discovering the new route by shipping proceeding to Benghazi from the northward. (19)
7 Nov 1941
At 0505B/7, in position 32°38'N, 20°02'E, HMS Unique (Lt. A.F. Collett, RN) picked up HE bearing 095°. The contact was moving northward. Nothing could be seen though.
At 0700B/7, HMS Unique was in position 32°32'N, 19°58'E, to intercept a small convoy expected to arrive at Benghazi.
This may have referred to the convoy made up of the Italian transport Bosforo (3648 GRT, built 1929) and the German transport Savona (2120 GRT, built 1934) which were to proceed from Brindisi to Benghazi escorted by the Italian torpedo boat Pegaso. This convoy had departed Brindisi around 2000B/4 for Benghazi but turned back the following morning due to the bad weather conditions encountered.
At 0900B/7, having sighted nothing of the convoy, HMS Unique proceeded eastwards for further reconnaissance of the northern end of the suspected mined area, observed earlier by HMS Thrasher (Lt. H.S. Mackenzie, RN).
From 1400B/7, HMS Unique patrolled near the vicinity of position 32°38'N, 19°48'E. (19)
8 Nov 1941
At 0800B/8, HMS Unique (Lt. A.F. Collett, RN) received Capt. S.10's signal timed 0133B/8 that a merchant vessels was expected to arrive at Bengazi between 2300B/8 and dawn on the 9th.
[We have been unable to identify this vessel.]
At 1230B/8, HMS Unique proceeded to the southward to patrol to the west of 19°51'E. In anticipation that southbound convoys to Bengazi may still be using the meridian of 19°51'E.
At 1700B/8, in position 32°31'N, 19°45'E, the Italian hospital ship Arno (7785 GRT, built 1912) was seen proceeding on course 320° at 14 knots.
At 2005B/8, received the Capt. S.10's signals timed 1927B/8 (probable new convoy route to Benghazi) and 1849B/8 (convoy of 5 merchant vessels and 4 destroyers prossible arrival time at Benghazi area between 0100B/9 and dawn on the 10th).
[We have been unable to identify a convoy which should have arrived at Benghazi around the time given in the signal.] (19)
9 Nov 1941
From 2100B/8 to 0150B/9, HMS Unique (Lt. A.F. Collett, RN) patrolled in the vicinity of position 32°31'N, 19°45'E.
From 0150B/8 to 1400B/9, HMS Unique patrolled in the vicinity of position 32°34'N, 19°48'E.
Nothing was sighted all day. (19)
10 Nov 1941
From 1620B/9 to 1230B/10, HMS Unique (Lt. A.F. Collett, RN) patrolled on line 140° from position 32°42'N, 19°43'E.
At 1230B/10, HMS Unique proceeded to the south-east to reconnoitre probable swept channel 157° from position 32°32'N, 19°55'E. Nothing was seen though.
At 1600B/10, in position 32°27'N, 20°01'E, HMS Unique turned to the north-west to resume patrol near position 32°42'N, 19°43'E.
At 1858B/10, Capt. S.10's signal timed 1735B/10 was received that a small convoy was expected to arrived at Benghazi from the west shortly after 0700B/11.
At 2200B/10, HMS Unique proceeded to patrol north-west of Benghazi in the vicinity of position 32°25'N, 19°35'E to intercept this small convoy.
The signal must have referred to the convoy made up of the transports Cadamosto (Italian, 1010 GRT, built 1905) and the Spezia (German, 1825 GRT, built 1924) that was on passage from Tripoli to Benghazi escorted by the Italian torpedo boat Centauro. (19)
11 Nov 1941
At 0600B/11, HMS Unique proceeded to the eastward to reconnoitre the north-west end of the swept channel, 311°, 15 miles from Benghazi light. Nothing was heard or seen from the expected convoy coming from Tripoli.
At 1100B/11, HMS Unique turned to the north-west to resume patrol to cover the northern convoy route to and from Benghazi.
At 1359B/11, the Capt. S.10's signal timed 1221B/11 was received which stated that one merchant vessel was expected to arrive from the northward at dawn on the 12th. Proceeded to position 32°38'N, 19°51'E to intercept this expected merchant vessel. (19)
12 Nov 1941
At 0058B/12, HMS Unique arrived in position 32°38'N, 19°51'E. A 4000 tons merchant vessels escorted by one destroyer was sighted bearing 000° at a range of 16000 yards. Enemy course was 180° at 9 knots.
The sea was calm with bright moonlight and when the target had closed to 10000 yards it was decided to continue the attack submerged as HMS Unique would otherwise certainly be sighted.
HMS Unique was approximately 2000 yards off track and the merchant vessel was observed to be steering a steady course. However at 0135B/11, the enemy altered course to 140° and put HMS Unique in a position 6000 yards on a 140° track. The target was closed at speed as this was thought at first to be a zig and not a navigational alteration of course, and it was impossible to carry out an attack, Unique therefore surfaced and followed the merchant vessel, in the hope of getting another opportunity of attacking.
At 0200B/12, the merchant vessel disappeared over the horizon having maintained a course of 140° since 0135B/11.
At 0640B/12, HMS Unique withdrew to the north-east after diving and remained deep in order to replace no.2 crank pin bearing of the starboard main engine which had run on 11 November, and its removal was necessary in order to effect repairs. A strong sea was now running and periscope depth was difficult to maintain except beam on to the sea.
At 1126A/12, in position 32°38'N, 19°58'E, HMS Unique, which had just gone deep for an aircraft, heard HE bearing 330°. An aircraft (Caproni Ca.310) was sighted bearing 325°. The enemy was at 300 feet proceeding on course 150°. Came up to periscope depth and sighted three Condottieri 'A'-class cruisers in position 32°43'N, 19°53'E, bearing 330° at a range of 10000 yards. Enemy course was 170° at 25 knots. These were first thought to be three destroyers but were identified at 1140B/11, as Condottieri 'A'-class cruisers.
HMS Unique was approximately 6000 yards off track and an attempt was made to close. On the next return to periscope depth an air escort was observed very close and turning towards. It was thought HMS Unique had been sighted as a heavy sea had forced the boat up to 20 feet.
At 1141B/12, HMS Unique went to 80 feet.
At 1146B/12, HMS Unique returned to periscope depth. The approach had to be broken off as the targets were too far off.
At 1855B/12, HMS Unique surfaced.
At 1949B/12, the Capt. S.10's signal timed 1915B/12, was received which reported three enemy cruisers steering 170° at 20 knots from Taranto. It was intended to pass an enemy report shortly after surfacing at 1855 hours but it was considered that the three enemy cruisers mentioned in this signal might follow up the others to carry out minelaying operations off Benghazi. The sending of an enemy report was therefore delayed until the following night in order to avoid being fixed by D/F bearings and thus jeopardising further chances of attack.
At 2300B/12, in position 32°32'N, 19°58'E, a destroyer was sighted bearing 210° at 10000 yards. Enemy course was 060° at 20 knots. Unique endeavoured to close to attack on the surface as there was no moonlight. However the attack was broken off when the enemy turned to the southward at 2325B/11.
At 2340B/12, HMS Unique turned to the northward to resume patrol in the vicinity of position 32°43'N, 19°53'E, in ordered to intercept the three enemy cruisers reported in Capt. S.10's signal timed 1915B/12. It was also considered that the three cruisers sighted in the forenoon would return by the northward convoy route from Benghazi during daylight on the 14th.
The cruisers sighted at 1126B/12, was most likely destroyers after all. The Italian destroyers Antonio Da Noli, Emanuele Pessagno and Nicolò Zeno were transporting troops to Benghazi and were most likely the ships sighted. (19)
13 Nov 1941
At 1905B/13, HMS Unique (Lt. A.F. Collett, RN) surfaced and proceeded towards position 32°40'N, 18°00'E in accordance with the Capt. S.10's signal timed 0931B/11 regarding the return route to Malta from patrol. (19)

5 Jan 1942
HMS Unique (Lt. A.F. Collett, DSC, RN) attacked the Italian battleship Littorio with torpedoes in the Gulf of Taranto in position 40°07'N, 17°07'E. All torpedoes fired missed their target despite the claim for a hit. The Italian battlegroup (including the battleship Giulio Cesare and destroyers Carabiniere, Alpino, Antonio da Noli, Antonio Pigafetta, Ascari and Fuciliere) was returning to Taranto after covering the Monviso convoy.

HMS Unique (Lt. A.F. Collett, DSC, RN) attacked an Italian submarine with four torpedoes about 25 nautical miles South-East of August, Sicily, Italy in position 36°55'N, 15°38'E. No hits were obtained.
According to Italian sources this was Ciro Menotti (C.C. Ugo Gelli) returning to Augusta from a transport mission to Tripoli but the attack was unobserved.
(All times are zone -1) 0700 hours - While Unique was in position 36°55'N, 15°38'E HE was heard bearing 110° moving left. Unique was at 70 feet and immediately went to periscope depth but nothing could be seen. HE changed bearing rapidly and it was thought that a destroyer or torpedo boat was nearby. The HE faded out after a few minutes. Later it was thought this might have been a submarine.
0716 hours - HE was reported bearing 160° and it was moving slowly to the right.
0720 hours - A small dark object was seen on this bearing and all tubes were brought to the ready.
0724 hours - It was thought the contact was an enemy submarine. Started attack but a good set up could not be immediately obtained.
0730 hours - Now also the high power (attack) periscope malfunctioned. The low power periscope now had to be used.
0737 hours - Four torpedoes were now finally fired from 2000 yards. They all missed and the submarine was lost from view at 0748 hours. (32)

13 Oct 1942
At 0845 hours (0945 hours, German time) on this day the German tanker Spichern (9323 GRT, built 1935, code name 'Elm', former Norwegian Krossfonn captured on 26 June 1940 by raider Widder) reported that a loud explosion was heard followed by a large column of water about 2000 meters away to port. From the same direction a torpedo track was seen. The Commanding Officer ordered hard to port and the torpedo was observed to run on a parallel course and miss about 50 metres from the port side. Fire was opened with 10.5 cm and 3.7 cm guns.
At 0855 hours (0955 hours, German time), a loud noise similar to a depth charge was heard and two more torpedo tracks were observed at about 3000 metres astern on the port side. They missed the port side by 70 metres. Position of these attacks as reported by Spichern was 46°54'N, 06°03'W.
Spichern was on her way back to France after she had been damaged by Allied aircraft while attempting to pass the Bay of Biscay for operations in the Atlantic on 12 October 1942. Shortly after these submarines attacks (at 1045 hours), her escort to St. Nazaire, the German minesweepers M 24, M 32 and M 152 joined her. Later (at 2345 hours) Sperrbrecher 175 joined for the last part of the passage into St. Nazaire. Spichern anchored in St. Nazaire at 0031/14.
At 0852 hours and 0854 hours, HMS Ursula (Lt. R.B. Lakin, DSC, RN), while in position 46°32'N, 05°55'W, heard two loud explosions. This position was about 23 nautical miles from the position reported by Spichern.
The torpedo attack on Spichern was not reported by any other submarine on patrol at that moment. The attacker must have been HMS Unique. No enemy report was received from Unique. It therefore is possible that HMS Unique was lost during the attack on Spichern. What is reported by Spichern looks like two attacks of two torpedoes. It seems like that during the first attack one of the torpedoes fired prematured possibly damaging Unique. It seems likely Unique was able to fire another two torpedoes against Spichern. Possibly the second explosion heard by Spichern was the demise of HMS Unique (Lt. R.E. Boddington, RN). (39)
