1Ragusa, Innocenzo2 Jan 19422155Messina6 Jan 19420935Messina410Patrolled southeast of Cape Passero, on aline 80 miles from Malta, between 36°00'N, 36°40'N, and between 15°40'E and 16°20'E, on a patrol line with submarines Onice, Delfino and Alagi. Left patrol on 5th January.
  3 Jan 19421005
(0) Off Murro di Porco.
At 0838 hours, the hydrophones picked up noises.

At 1005 hours, a large vessel was sighted at a distance of 8,000 metres, steering 190°.

At 1030 hours, it proved to be an Italian hospital ship of the AQUILEIA class and the attack was broken off.
  5 Jan 19420150
0155-0157 (e)
36° 00'N, 15° 40'EMARICOSOM had alerted the submarines Platino, Alagi, Manara and Delfino of the presence of an enemy submarine, reported at 0845 hours on 4th January, in Grid 3998/5 (3500' N, 15°30' E), steering 160°, 10 knots.

At 0150 hours, Platino sighted a submarine at a distance of 4,000 metres. She attempted a stern shot, but the target submerged and Platino did the same but could not regain contact.

This was ORP Sokol (Kpt. mar. Boris Karnicki). The Polish submarine had sighted the Italian submarine but mistook her for HMS Unbeaten.

2Ragusa, Innocenzo21 Jan 19421415Messina25 Jan 19421015Augusta502Sailed with the submarine Corallo and patrolled southeast of Malta, between 35°00'N and 35°20'N, and between 16°00'E and 16°20'E. Uneventful.
  23 Jan 19420254At 0254 hours, a derelict mine was sighted. Engines were stopped with the intention to destroy it by machine-gun fire, but the mine was lost from view in the low visibility.

3Ragusa, Innocenzo26 Jan 19420109Augusta29 Jan 19420845Augusta427Patrolled southeast of Malta, between 35°00'N and 35°20'N, and between 15°20'E and 15°40'E. Heard only hydrophone effects.

4Ragusa, Innocenzo10 Feb 19421830Augusta26 Feb 19421045Augusta1547Patrolled north of Cyrenaica, 8 miles from 34°10'N, 20°40'E on the meridian. On the evening of 15th February, was ordered to shift position 098° - 148 miles to form a patrol line with Menotti to intercept an enemy convoy. Nothing was sighted.
  14 Feb 1942063033° 35'N, 20° 41'EAt 0630 hours, a derelict mine was sighted and 50 rounds of 13.2mm ammunition were expended but without sinking it.
  14 Feb 19421100At 1100 hours, information was received of the passage of a convoy coming from the west. At 1241 hours, Platino heard H.E., believed to be from this convoy and, at 1447 hours, heard what appeared to be a torpedo hit but sighted nothing.
  16 Feb 19420210At 0210 hours, the silhouette of a submarine was sighted at a distance of 2,000 metres. It was probably Italian and part of the barrage line.

Ragusa, Innocenzo13 Mar 19421500Augusta13 Mar 19421800Augusta18Exercises escorted by the auxiliary Nuovo Avvenire.

5Ragusa, Innocenzo15 Mar 19421910Augusta30 Mar 19421010Augusta1365Patrolled north of Cyrenaica between 33°55'N and 34°05'N, and between 22°50'E and 23°50'E. Patrol marred by numerous engine defects. Carried S.I.C. torpedoes (magnetic pistols). Sighted only French ships.
  17 Mar 19421630
1630 (e)
34° 30'N, 21° 10'EAt 1630 hours, a Blenheim bomber attacked the submarine from the stern and from the sun. It dropped three small bombs (estimated at 50-kg) from a height of 500-600 metres, which fell 100 metres on the starboard side. The aircraft circled and attempted a new stern attack, but was met by the fire from the twin Breda machine-guns aft and desisted from the action. It circled again and attempted a new attack from the sun. The submarine opened fire at a range of 1,000 metres with the Breda machine-guns aft and at 500 metres with the forward machine gun. The aircraft flew away trailing smoke and T.V. Innocenzo Ragusa believed the aircraft had perhaps failed to reach its base.

This was Blenheim 'C' of 203 Squadron, piloted by Flight Lieutenant Green. The submarine was sighted 8 miles ahead, steering 116° at 8-9 knots. The aircraft climbed to 1,200 feet and dropped four 250lb depth charges. Green claimed that one bomb missed 5 yards from the starboard bow and another 10 yards on port bow. The aircraft strafed the submarine and one crew member was hit and fell backwards in the sea (no casualties were reported by the submarine). The aircraft was hit by antiaircraft rounds and suffered only minor damages, the rear-gunner was slightly wounded by splinters.
  17 Mar 1942175034° 28'N, 21° 19'EAt 1750 hours, nine Blenheim bombers were sighted at a distance of 4,000 metres and attacked Platino. Three turned toward the submarine who opened fire with the Breda twin mount aft, when the range had closed to 2,000 metres The three bombers opened fire with their machine-guns, but one of the aircraft, perhaps the squadron leader, appeared to have been hit and veered away. The other two desisted of the attack and the submarine crash-dived. Five bombs exploded over her, but Platino escaped by going down to 40 metres.

These were perhaps Beauforts of 39 Squadron.
  21 Mar 1942152034° 00'N, 23° 21'EAt 1520 hours, two destroyers and a steamer were sighted, steering 300°, 14 knots. This was expanded to a light cruiser of the DIDO class, four destroyers, a steamer and two motorships and the course was corrected to 320°. This was indeed C.S.15 (HMS Dido, etc.) with convoy MW.10 (HMS Breconshire, Clan Campbell, Talabot, Pampas, HMS Carlisle and five destroyers; these were the escort destroyers HMS Avon Vale, HMS Beaufort, HMS Dulverton, HMS Hurworth and HMS Southwold.).

The submarine took an intercepting course but lost contact at 1625 hours,
  23 Mar 1942160533° 38'N, 23° 17'EAt 1605 hours, several bomb explosions were heard indicating a convoy proceeding eastward, under air attack. An explosion believed to be a torpedo hit, had been heard earlier at 1440 hours (this was one of the torpedoes fired by Onice). The submarine heard also H.E. and depth-charges.
  23 Mar 1942180833° 38'N, 23° 17'E
(0) Approximately.
At 1808 hours, upon surfacing, the submarine observed two light cruisers of the DIDO class at a distance of 15,000 metres, steering 085°. These were probably HMS Dido and HMS Penelope. The submarine attempted to close but without success.
  27 Mar 1942072533° 27'N, 23° 55'EAt 0725 hours, a vessel was sighted at a distance of 13 miles, apparently steering toward Tobruk. It was too far to be intercepted.

  8 Nov 19420816At 0816 hours, a German aircraft was sighted and exchanged recognition signals.
  8 Nov 19421000At 1000 hours, an aircraft was seen and the submarine dived.
  8 Nov 19421220At 1220 hours, the Italian submarine Argo was encountered and exchanged recognition signals.

At 2104 hours, Platino was ordered to patrol off Cape Cavallo.
  9 Nov 19420543At 0543 hours, a submarine was sighted following a parallel course. It was believed to be Italian.
  9 Nov 1942181537° 20'N, 4° 00'EAt 1815 hours, firing and explosions could be observed in the distance. Platino tried to close but sighted nothing.
  10 Nov 1942080538° 15'N, 4° 30'EAt 0805 hours, a destroyer was sighted at 6,000 metres. Platino closed to attack but could not get to a distance of less than 4,000 meters.
  11 Nov 19422135At 2135 hours, the submarine Mocenigo was encountered and exchanged recognition signals.
  12 Nov 1942022836° 47'N, 5° 11'EAt 0030 hours, a light was sighted at a distance. It was believed to be a vessel afire in the Bay of Bougie,

At 0228 hours, against the light, a destroyer and four corvettes were sighted steering 110°. Shortly after, two more corvettes were also observed west of Cape Carbon. A corvette used a searchlight, but did not notice the submarine.

At 0259 hours, an aircraft flew over and dropped five flares. Platino dived.
  12 Nov 1942035936° 46'N, 5° 10'EAt 0359 hours, Platino had just surfaced, when a corvette was sighted at a distance of 400 metres. The submarine crash-dived to a depth of 120 metres but was not detected.
  12 Nov 1942050036° 46'N, 5° 10'E
(0) Approximately.
At 0500 hours, Platino was proceeding on the surface away from Bougie with the intention to return the following night, when a corvette was sighted at a range of 700 metres. A torpedo tube was made ready, but the corvette did not notice the submarine.
  13 Nov 1942013136° 46'N, 5° 07'EAt 0131 hours, a corvette was sighted on the starboard bow. Platino was on the surface and turned toward her, closing to 300 metres but was not in a favourable angle. Absolute silence was maintained and the corvette did not discover the submarine. Platino dived at 0142 hours and bottomed at 30 metres.

At 0150 hours, the submarine surfaced and watched the corvette disappear. The vessel on fire sighted earlier impeded the visibility. At 0233 hours, a corvette was sighted and appeared to be steering toward the submarine but continued on her way without incident.

  13 Nov 1942032636° 43'N, 5° 06'EAt 0235 hours, a dark shape was sighted and identified as a large merchant vessel outlined against Cape Carbon and a corvette was observed to be leaving the Bay of Bougie. At 0314 hours, a destroyer was sighted and there was some movements in the corvettes patrolling outside the bay.

At 0326 hours, four torpedoes (533mm) were fired from the bow tubes at a range of 1,000 metres aimed at the large merchant vessel. The depth was only 17 metres and the torpedoes were set for depths of 5 and 7 metres. The tracks of two torpedoes was observed to stop after 250 metres, leading T.V. Roberto Rigoli to believe they had been embedded in the mud. The other two were observed to hit the vessel amidships in a formidable explosion.

At 0345 hours, Platino dived and proceeded to leave the area. At 1401 hours, she reported her action in a signal. At 1652 hours, an order was received from MARICOSOM to return to base.

Unfortunately, this attack was not confirmed. Some Italian sources have claimed that the submarine sank the troop transport Narkunda (16,632 GRT, built 1920). This vessel was hit by two bombs and sunk as she was leaving from Bougie for Algiers at 1720 hours on 14th November, 31 killed, 211 survivors were picked up by the minesweeper HMS Cadmus.
  13 Nov 19421744At 1744 hours, a submarine was sighted apparently firing her four machine-guns and deck gun at an aircraft. Platino dived immediately.

  29 Jan 19430350At 0350 hours, a submarine was sighted at a distance of 4,000 metres on a southeasterly course. Platino had the moon behind her and elected to dive.
  30 Jan 19430017
0018 (e)
36° 56'N, 5° 40'EAt 2348 hours on 29th January, the lookout aft spotted a dark shape emerging from the mist on the starboard beam astern. The first reaction of T.V. Vittorio Patrelli Campagnano was to turn away as only his stern tubes were ready. They now appeared as small vessels and by midnight, the targets appeared to be corvettes and ten minutes later the forward tubes were readied to fire.

At 0017 hours on 30th January, four torpedoes (533mm, G7e type) were fired from the bow tubes at a range of 1,000 metres, at the corvettes. After 54 seconds (giving a running range of 750 metres) a hit was observed aft of the first corvette and 14 seconds later (run of 950 metres) two torpedoes hit the second corvette and she blew up in a tremendous explosion. After another 17 seconds, a third corvette appeared to have been hit giving a range of 1,200 metres. Platino turned to fire her stern torpedoes.

Only one corvette was hit, this was HMS Samphire (K 128, 925 tons) and she was sunk by a single torpedo hit. A total of two officers and thirty-one ratings were picked up, some by the escort destroyer HMS Zetland. Three officers and forty-two ratings killed or missing.

At 0023 hours, two stern torpedoes (533mm, S.I.C. type) were fired at a range of 2,000 metres aimed at an 8,000-ton freighter and one hit after 85 seconds (giving a rum of 1,900 metres) the vessel which blew up.

This result has not been confirmed by Allied sources.
  30 Jan 19430210At 0210 hours, a destroyer was sighted and the submarine dived.

  7 Feb 19432212
2200 (e)
37° 16'N, 6° 26'EAt 2147 hours, four vessels were sighted approaching at a distance of 5,000 metres. Shortly after, they could be made out as two large merchantmen escorted by two vessels making only about 6 knots. Platino closed at reduced speed as the phosphorescence of the sea could betray her presence.

At 2212 hours, four torpedoes were fired from the bow tubes (533mm, G7e type) at a range of 2,500 metres, aimed at the larger vessel described as a 10,000-ton freighter. Three minutes later, a hit was observed (giving a running range of 2,520 metres) and the vessel disappeared in a cloud of smoke.

The target was the British armed trawler HMT Tervani (409 tons) and she was hit and sunk. Tervani was towing the French water tanker Mory Mazout II (762 GRT, built 1908), escorted by the armed trawlers HMT Achroite (FY.914) and HMT Arnold Bennett (FY.1939). There were only two survivors. The two trawlers chased the submarine and left Mory Mazout II unattended. She was found derelict by the destroyer HMS Bicester escorting convoy M.K.S.8 and she detached the corvette HMCS Kitchener to stand by. Eventually the water tanker was towed to Philippeville by the tug HMS Jaunty.
  7 Feb 19432347
2347A (e)
37° 08'N, 6° 05'EAt 2315 hours, Platino was circling on the surface to renew the attack on the Mory Mazout II convoy, when a new convoy was observed to arrive at a distance of 6,000 metres. Initially, it was thought to consist of three large merchant ships escorted by four destroyers but was later assessed to be three large and two small merchant ships escorted by two destroyers.

At 2347 hours, two stern torpedoes (533mm, S.I.C. type) were fired at a range of 1,800 metres aimed at a 15,000-ton freighter. They were observed to miss closely ahead a destroyer and the merchant vessel suddenly turned to port and the torpedoes missed.

The target was Empire Dace (716 GRT, built 1942) of the REDRUTH convoy in company with two LSTs Mitsoa and Bachaquero and two merchant vessels bound from Philippeville to Oran, steering 250°, 11 knots, escorted by the minesweepers HMS Rothesay (s.o.), HMS Felixstowe (s.o. 13th Minesweeper Flotilla), HMS Polruan and HMS Brixham.

Felixstowe reported a torpedo missed her by only 3-5 yards and dropped four depth-charges but without observing any result.

  18 Feb 1943055537° 22'N, 5° 04'EAt 0440 hours and again at 0505 hours, firing was sighted straight ahead in the distance and was at first believed to the submarine Asteria under air attack (she had actually been sunk the previous day). By this time, it appeared that it was also a convoy under attack.

At 0543 hours, as Platino closed on the surface, shadows were sighted at a distance of 4,000 metres. The first one was identified as a destroyer leading the convoy, steering 090°.

At 0555 hours, four torpedoes were fired from the bow tubes (533mm, G7e type) at a distance of 700 metres aimed at the destroyer. The destroyer appeared to turn toward the submarine, but this only part of her zigzagging pattern. A minute later, Platino dived.

At 0559 hours, an explosion was heard giving a range of 3,600 metres. It was obvious that the destroyer had been missed but T.V. Patrelli Campagnano thought that he may have hit a vessel behind it.

Innocenzo Ragusa3 Jan 19421005(o) Off Murro di Porco.At 0838 hours, the hydrophones picked up noises.

At 1005 hours, a large vessel was sighted at a distance of 8,000 metres, steering 190°.

At 1030 hours, it proved to be an Italian hospital ship of the AQUILEIA class and the attack was broken off.

36.00 N, 15.40 E
(e) 36.23 N, 15.39 E
MARICOSOM had alerted the submarines Platino, Alagi, Manara and Delfino of the presence of an enemy submarine, reported at 0845 hours on 4th January, in Grid 3998/5 (3500' N, 15°30' E), steering 160°, 10 knots.

At 0150 hours, Platino sighted a submarine at a distance of 4,000 metres. She attempted a stern shot, but the target submerged and Platino did the same but could not regain contact.

This was ORP Sokol (Kpt. mar. Boris Karnicki). The Polish submarine had sighted the Italian submarine but mistook her for HMS Unbeaten.
Innocenzo Ragusa23 Jan 19420254At 0254 hours, a derelict mine was sighted. Engines were stopped with the intention to destroy it by machine-gun fire, but the mine was lost from view in the low visibility.
Innocenzo Ragusa14 Feb 1942063033.35 N, 20.41 E
At 0630 hours, a derelict mine was sighted and 50 rounds of 13.2mm ammunition were expended but without sinking it.
Innocenzo Ragusa14 Feb 19421100At 1100 hours, information was received of the passage of a convoy coming from the west. At 1241 hours, Platino heard H.E., believed to be from this convoy and, at 1447 hours, heard what appeared to be a torpedo hit but sighted nothing.
Innocenzo Ragusa16 Feb 19420210At 0210 hours, the silhouette of a submarine was sighted at a distance of 2,000 metres. It was probably Italian and part of the barrage line.
Innocenzo Ragusa17 Mar 19421630

34.30 N, 21.10 E
(e) 34.05 N, 20.55 E
At 1630 hours, a Blenheim bomber attacked the submarine from the stern and from the sun. It dropped three small bombs (estimated at 50-kg) from a height of 500-600 metres, which fell 100 metres on the starboard side. The aircraft circled and attempted a new stern attack, but was met by the fire from the twin Breda machine-guns aft and desisted from the action. It circled again and attempted a new attack from the sun. The submarine opened fire at a range of 1,000 metres with the Breda machine-guns aft and at 500 metres with the forward machine gun. The aircraft flew away trailing smoke and T.V. Innocenzo Ragusa believed the aircraft had perhaps failed to reach its base.

This was Blenheim 'C' of 203 Squadron, piloted by Flight Lieutenant Green. The submarine was sighted 8 miles ahead, steering 116° at 8-9 knots. The aircraft climbed to 1,200 feet and dropped four 250lb depth charges. Green claimed that one bomb missed 5 yards from the starboard bow and another 10 yards on port bow. The aircraft strafed the submarine and one crew member was hit and fell backwards in the sea (no casualties were reported by the submarine). The aircraft was hit by antiaircraft rounds and suffered only minor damages, the rear-gunner was slightly wounded by splinters.
Innocenzo Ragusa17 Mar 1942175034.28 N, 21.19 E
At 1750 hours, nine Blenheim bombers were sighted at a distance of 4,000 metres and attacked Platino. Three turned toward the submarine who opened fire with the Breda twin mount aft, when the range had closed to 2,000 metres The three bombers opened fire with their machine-guns, but one of the aircraft, perhaps the squadron leader, appeared to have been hit and veered away. The other two desisted of the attack and the submarine crash-dived. Five bombs exploded over her, but Platino escaped by going down to 40 metres.

These were perhaps Beauforts of 39 Squadron.
Innocenzo Ragusa21 Mar 1942152034.00 N, 23.21 E
At 1520 hours, two destroyers and a steamer were sighted, steering 300°, 14 knots. This was expanded to a light cruiser of the DIDO class, four destroyers, a steamer and two motorships and the course was corrected to 320°. This was indeed C.S.15 (HMS Dido, etc.) with convoy MW.10 (HMS Breconshire, Clan Campbell, Talabot, Pampas, HMS Carlisle and five destroyers; these were the escort destroyers HMS Avon Vale, HMS Beaufort, HMS Dulverton, HMS Hurworth and HMS Southwold.).

The submarine took an intercepting course but lost contact at 1625 hours,
Innocenzo Ragusa23 Mar 1942160533.38 N, 23.17 E
At 1605 hours, several bomb explosions were heard indicating a convoy proceeding eastward, under air attack. An explosion believed to be a torpedo hit, had been heard earlier at 1440 hours (this was one of the torpedoes fired by Onice). The submarine heard also H.E. and depth-charges.
Innocenzo Ragusa23 Mar 1942180833.38 N, 23.17 E
(o) Approximately.
At 1808 hours, upon surfacing, the submarine observed two light cruisers of the DIDO class at a distance of 15,000 metres, steering 085°. These were probably HMS Dido and HMS Penelope. The submarine attempted to close but without success.
Innocenzo Ragusa27 Mar 1942072533.27 N, 23.55 E
At 0725 hours, a vessel was sighted at a distance of 13 miles, apparently steering toward Tobruk. It was too far to be intercepted.
Innocenzo Ragusa20 Jul 19420807At 0807 hours, the submarine was surprised by an aircraft and had no time to submerge. Three or four rounds were fired with the machine-gun before it was recognised to be German Junker 88 bomber and fire was checked.
Roberto Rigoli5 Nov 19422250At 2250 hours, there was a leak and the rating Vittorio Mrak started a pump to deal with it. His leg was caught in the pump and he was severely injured. T.V. Roberto Rigoli signalled his intention to land the injured man at Palermo. The submarine met MAS 544 off Palermo, the injured man was transferred and the submarine resumed her course to Cagliari.
Roberto Rigoli8 Nov 19420816At 0816 hours, a German aircraft was sighted and exchanged recognition signals.
Roberto Rigoli8 Nov 19421000At 1000 hours, an aircraft was seen and the submarine dived.
Roberto Rigoli8 Nov 19421220At 1220 hours, the Italian submarine Argo was encountered and exchanged recognition signals.

At 2104 hours, Platino was ordered to patrol off Cape Cavallo.
Roberto Rigoli9 Nov 19420543At 0543 hours, a submarine was sighted following a parallel course. It was believed to be Italian.
Roberto Rigoli9 Nov 1942181537.20 N, 04.00 E
At 1815 hours, firing and explosions could be observed in the distance. Platino tried to close but sighted nothing.
Roberto Rigoli10 Nov 1942080538.15 N, 04.30 E
At 0805 hours, a destroyer was sighted at 6,000 metres. Platino closed to attack but could not get to a distance of less than 4,000 meters.
Roberto Rigoli11 Nov 19422135At 2135 hours, the submarine Mocenigo was encountered and exchanged recognition signals.
Roberto Rigoli12 Nov 1942022836.47 N, 05.11 E
At 0030 hours, a light was sighted at a distance. It was believed to be a vessel afire in the Bay of Bougie,

At 0228 hours, against the light, a destroyer and four corvettes were sighted steering 110°. Shortly after, two more corvettes were also observed west of Cape Carbon. A corvette used a searchlight, but did not notice the submarine.

At 0259 hours, an aircraft flew over and dropped five flares. Platino dived.
Roberto Rigoli12 Nov 1942035936.46 N, 05.10 E
At 0359 hours, Platino had just surfaced, when a corvette was sighted at a distance of 400 metres. The submarine crash-dived to a depth of 120 metres but was not detected.
Roberto Rigoli12 Nov 1942050036.46 N, 05.10 E
(o) Approximately.
At 0500 hours, Platino was proceeding on the surface away from Bougie with the intention to return the following night, when a corvette was sighted at a range of 700 metres. A torpedo tube was made ready, but the corvette did not notice the submarine.
Roberto Rigoli13 Nov 1942013136.46 N, 05.07 E
At 0131 hours, a corvette was sighted on the starboard bow. Platino was on the surface and turned toward her, closing to 300 metres but was not in a favourable angle. Absolute silence was maintained and the corvette did not discover the submarine. Platino dived at 0142 hours and bottomed at 30 metres.

At 0150 hours, the submarine surfaced and watched the corvette disappear. The vessel on fire sighted earlier impeded the visibility. At 0233 hours, a corvette was sighted and appeared to be steering toward the submarine but continued on her way without incident.

Roberto Rigoli13 Nov 1942032636.43 N, 05.06 E
At 0235 hours, a dark shape was sighted and identified as a large merchant vessel outlined against Cape Carbon and a corvette was observed to be leaving the Bay of Bougie. At 0314 hours, a destroyer was sighted and there was some movements in the corvettes patrolling outside the bay.

At 0326 hours, four torpedoes (533mm) were fired from the bow tubes at a range of 1,000 metres aimed at the large merchant vessel. The depth was only 17 metres and the torpedoes were set for depths of 5 and 7 metres. The tracks of two torpedoes was observed to stop after 250 metres, leading T.V. Roberto Rigoli to believe they had been embedded in the mud. The other two were observed to hit the vessel amidships in a formidable explosion.

At 0345 hours, Platino dived and proceeded to leave the area. At 1401 hours, she reported her action in a signal. At 1652 hours, an order was received from MARICOSOM to return to base.

Unfortunately, this attack was not confirmed. Some Italian sources have claimed that the submarine sank the troop transport Narkunda (16,632 GRT, built 1920). This vessel was hit by two bombs and sunk as she was leaving from Bougie for Algiers at 1720 hours on 14th November, 31 killed, 211 survivors were picked up by the minesweeper HMS Cadmus.
Roberto Rigoli13 Nov 19421744At 1744 hours, a submarine was sighted apparently firing her four machine-guns and deck gun at an aircraft. Platino dived immediately.
Vittorio Patrelli Campagnano29 Jan 19430350At 0350 hours, a submarine was sighted at a distance of 4,000 metres on a southeasterly course. Platino had the moon behind her and elected to dive.

At 2348 hours on 29th January, the lookout aft spotted a dark shape emerging from the mist on the starboard beam astern. The first reaction of T.V. Vittorio Patrelli Campagnano was to turn away as only his stern tubes were ready. They now appeared as small vessels and by midnight, the targets appeared to be corvettes and ten minutes later the forward tubes were readied to fire.

At 0017 hours on 30th January, four torpedoes (533mm, G7e type) were fired from the bow tubes at a range of 1,000 metres, at the corvettes. After 54 seconds (giving a running range of 750 metres) a hit was observed aft of the first corvette and 14 seconds later (run of 950 metres) two torpedoes hit the second corvette and she blew up in a tremendous explosion. After another 17 seconds, a third corvette appeared to have been hit giving a range of 1,200 metres. Platino turned to fire her stern torpedoes.

Only one corvette was hit, this was HMS Samphire (K 128, 925 tons) and she was sunk by a single torpedo hit. A total of two officers and thirty-one ratings were picked up, some by the escort destroyer HMS Zetland. Three officers and forty-two ratings killed or missing.

At 0023 hours, two stern torpedoes (533mm, S.I.C. type) were fired at a range of 2,000 metres aimed at an 8,000-ton freighter and one hit after 85 seconds (giving a rum of 1,900 metres) the vessel which blew up.

This result has not been confirmed by Allied sources.
Vittorio Patrelli Campagnano30 Jan 19430210At 0210 hours, a destroyer was sighted and the submarine dived.

(e) 37.10 N, 06.30 E
At 2147 hours, four vessels were sighted approaching at a distance of 5,000 metres. Shortly after, they could be made out as two large merchantmen escorted by two vessels making only about 6 knots. Platino closed at reduced speed as the phosphorescence of the sea could betray her presence.

At 2212 hours, four torpedoes were fired from the bow tubes (533mm, G7e type) at a range of 2,500 metres, aimed at the larger vessel described as a 10,000-ton freighter. Three minutes later, a hit was observed (giving a running range of 2,520 metres) and the vessel disappeared in a cloud of smoke.

The target was the British armed trawler HMT Tervani (409 tons) and she was hit and sunk. Tervani was towing the French water tanker Mory Mazout II (762 GRT, built 1908), escorted by the armed trawlers HMT Achroite (FY.914) and HMT Arnold Bennett (FY.1939). There were only two survivors. The two trawlers chased the submarine and left Mory Mazout II unattended. She was found derelict by the destroyer HMS Bicester escorting convoy M.K.S.8 and she detached the corvette HMCS Kitchener to stand by. Eventually the water tanker was towed to Philippeville by the tug HMS Jaunty.

37.08 N, 06.05 E
(e) 37.00 N, 06.02 E
At 2315 hours, Platino was circling on the surface to renew the attack on the Mory Mazout II convoy, when a new convoy was observed to arrive at a distance of 6,000 metres. Initially, it was thought to consist of three large merchant ships escorted by four destroyers but was later assessed to be three large and two small merchant ships escorted by two destroyers.

At 2347 hours, two stern torpedoes (533mm, S.I.C. type) were fired at a range of 1,800 metres aimed at a 15,000-ton freighter. They were observed to miss closely ahead a destroyer and the merchant vessel suddenly turned to port and the torpedoes missed.

The target was Empire Dace (716 GRT, built 1942) of the REDRUTH convoy in company with two LSTs Mitsoa and Bachaquero and two merchant vessels bound from Philippeville to Oran, steering 250°, 11 knots, escorted by the minesweepers HMS Rothesay (s.o.), HMS Felixstowe (s.o. 13th Minesweeper Flotilla), HMS Polruan and HMS Brixham.

Felixstowe reported a torpedo missed her by only 3-5 yards and dropped four depth-charges but without observing any result.
Vittorio Patrelli Campagnano18 Feb 1943055537.22 N, 05.04 E
At 0440 hours and again at 0505 hours, firing was sighted straight ahead in the distance and was at first believed to the submarine Asteria under air attack (she had actually been sunk the previous day). By this time, it appeared that it was also a convoy under attack.

At 0543 hours, as Platino closed on the surface, shadows were sighted at a distance of 4,000 metres. The first one was identified as a destroyer leading the convoy, steering 090°.

At 0555 hours, four torpedoes were fired from the bow tubes (533mm, G7e type) at a distance of 700 metres aimed at the destroyer. The destroyer appeared to turn toward the submarine, but this only part of her zigzagging pattern. A minute later, Platino dived.

At 0559 hours, an explosion was heard giving a range of 3,600 metres. It was obvious that the destroyer had been missed but T.V. Patrelli Campagnano thought that he may have hit a vessel behind it.
Vittorio Patrelli Campagnano12 Apr 19431045At 1045 hours, the submarine Benedetto Brin was sighted. She had also been sighted at dawn.
Vittorio Patrelli Campagnano1 Jun 19431350At 1350 hours, a derelict mine was sighted and repeatedly hit with light machine-guns but it did not explode or sink.
Vittorio Patrelli Campagnano18 Jun 19432245At 2245 hours, information was received of a convoy proceeding off the Algerian coast. For most of the next day, Platino proceeded to intercept. The convoy was then reported off Cape de Fer but no contact was made.
Vittorio Patrelli Campagnano19 Jun 1943231937.05 N, 07.10 E
(o) Approximately.
At 2319 hours, an aircraft was seen and dropped a flare 200 metres from Platino. The submarine dived and heard bombs exploding a few minutes later.

37.05 N, 07.10 E
(e) 37.36 N, 07.42 E
At 0546 hours, an aircraft was sighted which passed close to the submarine. Platino dived but was not attacked.

This was Hudson 'J' (FK.711) of 608 Squadron piloted by Flight Sergeant B. Linnell. It made a radar contact but was unable to attack.
Vittorio Patrelli Campagnano10 Jul 19431009At 1009 hours, an aircraft was seen and the submarine dived.
Vittorio Patrelli Campagnano10 Jul 19431239At 1239 hours, an aircraft was seen and the submarine dived.
Vittorio Patrelli Campagnano10 Jul 19431703At 1703 hours, an aircraft was seen and the submarine dived.
Vittorio Patrelli Campagnano10 Jul 19432031At 2031 hours, an aircraft was seen and the submarine dived.
Vittorio Patrelli Campagnano11 Jul 19430130(o) Probably south of Sardinia.At 0130 hours, an Italian submarine was sighted. It did not appear to be Diaspro.
Vittorio Patrelli Campagnano18 Jul 19431150At 1150 hours, an enemy destroyer was sighted at a distance of 6,000 metres.
Vittorio Patrelli Campagnano18 Jul 19431407At 1407 hours, an enemy destroyer was sighted on a southeast course.
Vittorio Patrelli Campagnano18 Jul 1943141237.12 N, 15.21 E
Between 1127 and 1150 hours, the masts and funnel of a destroyer were observed through the periscope at a distance of 6,000 metres.

At 1349-1407 hours, a destroyer was again sighted.

At 1412 hours, a 15-16,000-ton two-funnel troop transport in a convoy was observed leaving Augusta.

At 1428 hours, four torpedoes (533mm, G7e type) were fired at a range of 3,500-4,000 metres, aimed a this transport. Upon firing, Platino went deep. An explosion was heard after 6 minutes giving a running range of 5,040 metres.

The target was the troop transport HMS Ulster Monarch (3,791 tons, built 1930) in company with the commando troopships HMS Princess Beatrix (4,135 tons, built 1939) and HMS Prins Albert (2,938 tons, built 1937). They had just left harbour at 1400 hours, escorted by the escort destroyers HMS Ledbury, HMS Blencathra, HMS Quantock and one other. It was missed.
Vittorio Patrelli Campagnano20 Jul 19431344At 1344 hours, a large formation of American four-engine bombers was seen and the submarine dived.
Vittorio Patrelli Campagnano30 Jan 1944001445.08 N, 12.19 E
(o) South of Adige River.
At 0014 hours, five agents from three missions were landed. An Italian Air Force Captain, Bruno Rossoni of Padua and an Italian Air Force Petty Officer Gateano Neglia of Palermo ("PEAR" mission), an Italian Army Lieutenant Egon De Basseggio from Trieste ("FIG" mission) and the third mission was headed by Italian Captain Cristoforo De Hartungen from Bolzano with his W/T operator, an Italian Navy seaman Salvatore Amodio from Palermo ("PLUM" mission) . They made contact by radio on 9th February 1944. Corvo may have mixed up the teams in his book.
Vittorio Patrelli Campagnano31 Jan 1944001545.15 N, 13.35 E
(o) Approximately.
At 0015 hours, two agents were landed.
Vittorio Patrelli Campagnano20 Feb 19442157(o) One mile from Punta Del Dente on 45.18 N parallel (south of Cortelazzo).At 2157 hours, three SOE agents (Special operation IAGO) were landed.
Vittorio Patrelli Campagnano21 Feb 1944230844.44.5 N, 12.15 E
(o) Near Comacchio.
At 2308 hours, six or nine OSS agents were landed. These were special operations FALSTAFF and CORDELIA and Mission ZELLA (Antonio Farneti, Celso Minardi and Alberto Grimaldi). According to the head of mission ZELLA, Antonio Farneti, they left at 2130 hours on the 21st, but because of heavy seas, they reached the coast only at 0230 hours on 22nd.
Vittorio Patrelli Campagnano22 Mar 1944011544.44 N, 12.16 E
At 0115 hours, the submarine landed four OSS agents (in all seven persons according to the patrol report) (operation ATHOS).

Vittorio Patrelli Campagnano24 Apr 1944011045.33.5 N, 12.48 E
At 0110 hours, four agents were landed. They were reported as three OSS agents (Special operation ACORN and operation LEEDS?).

At 0150 hours, the submarine heard shots being fired and it was believed the party had been discovered.
Vittorio Patrelli Campagnano26 Jun 1944010344.42.5 N, 12.27 E
At 0103 hours, the submarine landed three agents (operation DRUPE) and picked up one person. One of the agents landed was the radio operator Arturo 'Tonino' Spazzoli who collaborated with the ZELLA mission, accompanied by two radio operators Pasquale Recapito and Italo Turco. Spazzoli was later caught and executed by the Germans.

All Italian submarines
