  29 May 1941162536° 59'N, 17° 26'EAt 1625 hours, a derelict mine was sighted at a distance of 1,000 metres. An attempt to destroy it by machine-gun fire failed.
  6 Jun 1941032532° 10'N, 25° 20'EAt 0325 hours, a destroyer was sighted at a range of 3,000 metres, steering 100° at 15 knots. Alagi maneuvered on the surface at 7 knots to carry out a stern attack but was thwarted when a second destroyer appeared at 1,500 metres. She crash-dived and was not detected. In the following days she sighted only small fishing vessels.
  12 Jun 19411947
(0) Approximately.
At 1947 hours, a Sunderland was sighted steering 290°. Alagi was proceeding on the surface at 9.5 knots and T.V. Giulio Contreas elected to fight it out. The aircraft passed ahead at a height of 100 metres, flashing white lights and ineffectively strafing the submarine. Alagi's light and heavy machine-guns opened fire, claiming repeated hits. The aircraft came back and dropped two bombs, which fell astern of the submarine, without causing damage. However, this time its firing was accurate and hit the conning tower with 15 rounds, mortally wounding gunner Paolo Nuzzo and slightly wounding another. The aircraft was hit and disappeared trailing smoke. Contreas believed that it may have been shot down.

This was a Sunderland from Malta, but the report seems to have been lost.

Giulio Contreas thought that he had a chance to intercept and altered course at maximum speed (9 knots as one of his diesels had defects). From 1935 to 2035 hours, hydrophone effects were heard from this vessel, but it was faster than expected and contact was lost.

At 2245 hours, Alagi was informed of an armed steamer apparently damaged in 37°24' N, 06°54' E and ordered to attack it. This was Deucalion attacked by Bandiera.

At 2007 hours, Alagi had come to periscope depth and observed a freighter, escorted by a destroyer, steering 170°. As T.V. Sergio Puccini had not been informed of the passage of Italian ships in this area, at that time, he assumed they were enemy ships and prepared for an attack.

At 2020 hours, the range had closed to 5,000 metres and the flag could be seen, but Puccini could not make out the colours. However, the destroyer was recognised to be of typically British design with four guns in single mounts. Twenty minutes later, another destroyer and two more freighters appeared.

At 2119 hours, three torpedoes (533mm) were fired from bow tubes at ranges varying from 2,000 to 3,000 metres. The "senza bolla" (bubbleless) apparatus failed to work properly and the submarine briefly broke surface. After 3 minutes, a loud explosion was heard followed, very quickly, by three fairly close depth-charge explosions.

At 0007 hours on 9th June, the submarine made an enemy report. However, the success was soon turned into tragedy:

Her victim was the destroyer Usodimare (1917 tons) in convoy with the transports Vettor Pisani (6,339 GRT, built 1939) and Sestriere (7,993 GRT, built 1942), the destroyer Premuda and the torpedo-boat Circe steering 180°, 13 knots. It was the presence of the war prize Premuda (ex-Yugoslav, built in England) who had induced Puccini in error. Usodimare had seen a torpedo track and put the helm hard to starboard, but it was too late. The torpedo struck in boiler room no. 3, breaking her in two and she sank in about 20-30 seconds. The torpedo boat Cigno, MAS 563 and MAS 564 were sailed from Trapani to join Circe to look for the survivors. Five officers and 160 ratings were saved, six officers and 115 ratings were missing (the total included 30 passengers).

37° 36'N, 9° 53'ESince 10th June, MARICOSOM had informed the submarines of ships leaving Gibraltar in an easterly direction, obviously a new attempt to supply Malta.

At 0103 hours, Alagi was informed that this force consisted of a battleship, three destroyers, ten escort vessels and a number of transports. This was rectified at 0735 hours as two aircraft carriers, a battleship, three cruisers and destroyers sighted at 0605 hours in Italian Grid 5801/2, steering 090°, 16 knots. More signals followed.

At 1745 hours, the convoy was sighted through the periscope, in 37°38' N, 09°51' E at distances varying from 10,000 to 20,000 metres.

At 1810 hours, the range was down to 4,000 metres and Alagi now proceeded submerged to close at a depth of 15 metres.

At 1925 hours, a steamer was observed to be hit by a bomb. Five minutes later, a battleship was sighted at a distance of 15,000 metres, steering 335.5° and, at 2045 hours, a cruiser was sighted listing heavily to port. At the same time, to the eastward, an aircraft carrier and a battleship were sighted, followed shortly after by a second aircraft carrier in the process of landing her aircraft at a distance of 7-8,000 metres.

At 2105 hours, two torpedoes (one 533mm and one 450mm) were fired from the stern tubes at a range of 1,500 metres aimed at an aircraft carrier. Due to an error in transmission the 533mm torpedo was fired at an angle of 060° to port instead of to starboard. Alagi now only had one 450mm torpedo left in a forward tube. Both torpedoes missed.

The target was probably the aircraft carrier HMS Eagle with the battleship HMS Malaya, the aircraft carrier HMS Argus and the light cruisers HMS Kenya and HMS Charybdis, screened by destroyers.

Alagi was hunted and depth-charged by the destroyer HMS Marne and then by the minesweeper HMS Speedy who dropped five depth charges. The submarine was claimed probably sunk but escaped damage.

34° 59'N, 35° 32'EAt 1935 hours, an illuminated ship was sighted at a distance of 10,000 metres. Twenty minutes later, it was identified as an 8-10,000-ton tanker and shortly after recognised as Turkish. She was steering 200° at 12 knots.

At 2004 hours, two torpedoes (533mm) were fired from bow tubes at a distance of 400 metres. About 20 seconds later, a double explosion occurred.

This was the Turkish Antares (3,723 GRT, 1893) on a trip from Alexandretta to Haifa. She was hit by only one torpedo, in the engine room and, had to be beached in 34°48'50" N, 35°52' E, near Tartus, Syria. Refloated on 27th July, with the assistance of the HM tug Henrietta Moller, HM tug Tientsin, the armed whaler HMSAS Southern Isles and the Free French armed trawler Reine des Flots, she was towed to Iskanderun.
  14 Jul 1942014533° 50'N, 34° 59'EAt 0145 hours, a destroyer was sighted. At 0157 hours. Alagi attempted to fire her two stern tubes from about 1,000 meters, but could not get into a good attacking position.
  14 Jul 1942062533° 50'N, 34° 59'EAt 0625 hours, a destroyer was sighted steering 040°. A second destroyer was sighted shortly after, on a northerly course and both hunted the submarine until 1230 hours. Alagi rigged for silent running and escaped.
  16 Jul 1942133534° 05'N, 29° 18'EAt 1335 hours, an aircraft was seen and the submarine dived.

  12 Aug 19422105
2111 (e)
37° 26'N, 10° 36'EAt 2000 hours, a huge column of smoke was observed through the periscope at about 20,000 metres. Alagi steered toward it.

At 2020 hours, the convoy came under air attack and put a up a fierce antiaircraft barrage. A destroyer was hit by a bomb. T.V. Puccini counted fifteen vessels of the cruisers, destroyers and freighter types.

At 2100 hours, a violent air attack occurred and two steamers were hit by bombs. At that time the submarine was about 3-4,000 metres away.

At 2105 hours, four torpedoes (533mm) were fired from the bow tubes at a distance of 1,500-2,000 metres aimed at a SOUTHAMPTON class cruiser. Alagi heard three explosions as she dived to the bottom at a depth of 90 metres. Puccini believed that no three hits could have hit the cruiser so perhaps a freighter or a destroyer had also been hit.

The light cruiser HMS Kenya was indeed damaged, hit in the bow (three killed, one wounded), a second torpedo passed under and two more narrowly missed her stern and she returned to Gibraltar escorted by four destroyers. In some books, Clan Ferguson was claimed sunk in this attack. She was actually sunk by JU-88s at 0810 hours on the 13th. Survivors of Clan Ferguson (of a crew of 101+13 passengers, 12 were killed) reported to have been torpedoed at 2105 hours (according to Italian authorities), although they claimed to have been hit by a torpedo-bomber, there were no torpedo-bomber attacks at the time. The destroyers HMS Ashanti, HMS Penn and the escort destroyer HMS Derwent hunted the submarine but without success.
  14 Aug 19420550+At 0550 hours, the conning tower of a submarine was sighted disappearing in the distance.

  8 Nov 1942115837° 24'N, 10° 14'EAt 1158 hours, Alagi had been at periscope depth to listen to her radio when suddenly a loud noise was heard and she was shoved to a depth of 24 meters. The submarine then dived to 70 meters. Initially it was believed that the submarine had been bombed by aircraft. Her two periscopes were damaged and there were other damages to the conning tower. Later, TV. Puccini believed that he had collided with another submarine.

Alagi had indeed collided with the submarine Diaspro. She was forced to abort her mission.

37° 28'N, 5° 18'EAt 1900 hours, Alagi was illuminated by a searchlight of an enemy bomber which was sighted at only 500 metres. It flew over the submarine at an altitude of 100 metres and dropped two bombs. Luckily, they missed the stern by 30 to 50 metres. Alagi immediately crash-dived after the explosions.

This was Wellington 'Z' of 179 Squadron. It had detected the submarine at 6 miles and switched the Leigh light when it had closed at half a mile. It dropped four Mark XI Torpex depth-charges from a height of 70 feet and observed one exploding 30 feet from the stern of the submarine. The aircraft circled in the area. When the submarine surfaced at 2000 hours, the aircraft was still there and Alagi had to submerge again.

These were most likely the British MGB-646, MGB-643 and MGB-641 of the 19th MGB Flotilla.
  15 Jul 1943150037° 33'N, 15° 44'EAt 1500 hours, submarine of the BRONZO class was sighted at a distance of 2,000 metres on the surface, steering 180°. This was most probably Nichelio, who had just surfaced and was proceeding to zone 83 (rectangle between 36°50' N and 37°00' N and between 15°20' E and 15°40' E).
  16 Jul 1943010037° 06'N, 15° 51'EAt 0100 hours, a submarine was sighted at distance of 4,000 metres. Alagi continued toward her patrol position.

37° 02'N, 15° 55'EAt 0600 hours, three destroyers were observed through the periscope. They were believed to be the same as those sighted earlier.

At 0613 hours, three torpedoes (533mm, G7e type) were fired from the bow tubes (a fourth misfired) at a range of 700-1,200 metres. After 105 seconds a loud explosion was heard giving a running range of 1,500 metres. Alagi went deep to 70-90 metres and, at 0635 hours, heard two escort vessels followed by two patterns of depth charges, but escaped damage.

The target was actually the light cruiser HMS Cleopatra, proceeding in company with the light cruiser HMS Euryalus, escorted by the destroyers HMS Quilliam and HMS Quail. Cleopatra was damaged by one torpedo hit (twenty-three killed), her speed was reduced to 4.5 knots. However, she soon managed to increase speed to 10 knots and was joined by HMS Euryalus who was within sight. At 0938 hour, she was joined by HMS Eggesford, HMS Seaham, HMS Poole, HMS Oriana and HMS Baltimore (?) [listed in the C. in C. Mediterranean diaries, ADM199/640, TNA, but no such ship existed] and escorted to Malta.

Giulio Contreas29 May 1941162536.59 N, 17.26 E
At 1625 hours, a derelict mine was sighted at a distance of 1,000 metres. An attempt to destroy it by machine-gun fire failed.
Giulio Contreas6 Jun 1941032532.10 N, 25.20 E
At 0325 hours, a destroyer was sighted at a range of 3,000 metres, steering 100° at 15 knots. Alagi maneuvered on the surface at 7 knots to carry out a stern attack but was thwarted when a second destroyer appeared at 1,500 metres. She crash-dived and was not detected. In the following days she sighted only small fishing vessels.
Giulio Contreas12 Jun 19411947(e) 34.30 N, 19.00 E
(o) Approximately.
At 1947 hours, a Sunderland was sighted steering 290°. Alagi was proceeding on the surface at 9.5 knots and T.V. Giulio Contreas elected to fight it out. The aircraft passed ahead at a height of 100 metres, flashing white lights and ineffectively strafing the submarine. Alagi's light and heavy machine-guns opened fire, claiming repeated hits. The aircraft came back and dropped two bombs, which fell astern of the submarine, without causing damage. However, this time its firing was accurate and hit the conning tower with 15 rounds, mortally wounding gunner Paolo Nuzzo and slightly wounding another. The aircraft was hit and disappeared trailing smoke. Contreas believed that it may have been shot down.

This was a Sunderland from Malta, but the report seems to have been lost.
Giulio Contreas24 Jul 1941175837.45 N, 04.50 E
At 1758 hours, an aircraft carrier and two destroyers were sighted at a distance of 15,000 metres, steering 085°. Alagi could not get within attacking range.

This was the aircraft carrier HMS Ark Royal carrying out operation SUBSTANCE.
Giulio Contreas25 Jul 19411527(o) North of Cape Bougaroni.At 1527 hours, an aircraft carrier, two cruisers and several destroyers were sighted steering 030°, then moving westward. Alagi could not get into an attacking position, losing visual contact at 1643 hours and hydrophone contact at 1932 hours.

This was the aircraft HMS Ark Royal and other ships retiring westward (Operation SUBSTANCE).
Giulio Contreas3 Aug 1941232737.33 N, 05.03 E
At 0300 hours, information was received of an important convoy sighted, at 2220 hours on 2nd August, in Italian Grid 8327/5, steering 270° at 16 knots. Alagi was ordered to shift her patrol 20 miles south.

At 2327 hours, an illuminated vessel was sighted steering 325°. It was probably French.
Giulio Contreas4 Aug 1941033037.29 N, 05.08 E
At 0330 hours, an illuminated vessel, probably French, was sighted steering 150°.
Giulio Contreas27 Aug 1941122438.25 N, 07.22 E
At 2233 hours on 26th August, MARICOSOM informed Alagi of the presence of three enemy merchant ships and she proceeded to intercept.

At 0011 hours, the submarine received the order to return to base.

At 1224 hours, a signal from MARICOSOM (1135/27) informed Alagi of a 10-20,000-ton transport in Grid 6580/6, steering 270° at 15 knots. T.V. Giulio Contreas thought that he had a chance to intercept and altered course at maximum speed (9 knots as one of his diesels had defects). From 1935 to 2035 hours, hydrophone effects were heard from this vessel, but it was faster than expected and contact was lost.

At 2245 hours, Alagi was informed of an armed steamer apparently damaged in 37°24' N, 06°54' E and ordered to attack it. This was Deucalion attacked by Bandiera.

Giulio Contreas28 Aug 1941104037.24 N, 06.50 E
At 0013 hours on the 28th, the submarine was informed of an Italian aircraft shot down and ordered look for survivors.

At 1040 hours, a body was sighted floating in the sea and was recovered. It was T.V. Antonio Forni, naval observer. No survivors were found.
Giulio Contreas29 Aug 19410845(o) At entrance of Cagliari.At 0845 hours, the body of T.V. Antonio Forni was transferred to the tug Vado.
Giulio Contreas20 Sep 1941101537.08.25 N, 11.02.15 E
At 1015 hours, an Italian 20,000-ton motor-ship escorted by four destroyers were sighted on a northerly course. Alagi had been informed of their passage and remained submerged at a depth of 20 meters, with one destroyer passing over her exactly seven minutes later .

This was the troop transport Vulcania escorted by the destroyers Da Recco, Da Noli, Pessagno and Usodimare travelling from Tripoli to Naples.
Giulio Contreas17 Oct 1941084138.25 N, 08.15 E
At 0841 hours, an aircraft was seen at a distance of 7,000 metres and the submarine dived.
Giulio Contreas18 Oct 1941050037.17 N, 06.32 E
At 0500 hours, a steamer was observed at a distance of 10,000 metres. Alagi could not close to investigate.

At 1405 hours, the submarine received a signal from MARICOSOM (1245/18) indicating an aircraft carrier, a battleship and six destroyers steering 090°, 14 knots at 1132 hours in Italian Grid 9319/5, about 120 miles away.

This was the aircraft carrier HMS Ark Royal, the battleship HMS Rodney, the light cruiser HMS Hermione and seven destroyers carrying out operation CALLBOY.

The submarine altered course to intercept but could not make contact.
Giulio Contreas5 Dec 1941204037.38.5 N, 07.27 E
At 2040 hours, a submarine or antisubmarine vessel was sighted at a distance of 4,000 metres. Alagi was not in a favourable position and T.V. Contreas elected to submerge.
Giulio Contreas19 Dec 1941100037.44 N, 07.38 E
At 1000 hours, a submarine similar to Aradam was sighted steering 070°. Alagi dived immediately.
Giulio Contreas6 Jan 1942100034.55 N, 13.17 E
At 1000 hours, a derelict mine was seen 300 metres away. No attempts were made to destroy it as the heavy seas made the aiming difficult.
Marco Revedin9 Feb 1942074038.00 N, 07.30 E
(o) Very approximate position.
0740 hours, a sudden wave carried out the starboard lookout Cosimos Desogus. The submarine turned back and searched until 0900 hours, but he was never found.
Marco Revedin10 Feb 19421405At 1405 hours, information was received of an enemy cruiser and a destroyer sighted at 1215 hours in Italian Grid 6291/5 steering 090° at 20 knots, 190 miles away.

Alagi altered course to westward to intercept, but a new MARICOSOM signal (1702/10) reported them in Grid 1814/6, at 1345 hours, on course 090°, 22 knots. This meant the enemy would be passing 20 miles to the north of her position, the submarine tried to close but only heard H.E.

These were the light cruiser HMS Cleopatra and the destroyer HMS Fortune who arrived at Malta at noon on 11th February.
Marco Revedin11 Feb 1942041537.20 N, 07.05 E
At 0415 hours, a steamer was observed on a westerly course. Alagi trailed her until she was recognised as the French Saint Alain (1,956 GRT, built 1930).
Marco Revedin11 Feb 1942060537.11 N, 07.11 E
At 0605 hours, a steamer was sighted steering 280°. Upon closing, it proved to be French.

At 1415 hours, Alagi was informed of the passage of an enemy ship, but was too far to take any action.
Marco Revedin12 Feb 1942021037.17 N, 07.01 E
At 0210 hours, two ships were sighted. Upon closing, one was identified as the French Château Larose (2,047 GRT, built 1930).
Marco Revedin13 Feb 1942010037.27 N, 06.58 E
At 0100 hours, two ships, navigating with lights and following the coast, were sighted on the horizon.
Sergio Puccini30 May 1942223037.45.10 N, 12.06.20 E
At 2230 hours, a sailing vessel was sighted. Alagi altered away to avoid being seen.
Sergio Puccini8 Jun 1942120038.21 N, 12.35 E
At 1200 hours, an Italian aircraft was seen flying in a southerly direction.
Sergio Puccini8 Jun 1942123238.24 N, 12.15 E
At 1232 hours, a derelict mine was sunk by machine-gun fire.
Sergio Puccini8 Jun 1942123538.23 N, 12.16 E
At 1235 hours, an Italian aircraft was seen flying in a northerly direction.
Sergio Puccini8 Jun 1942150738.27 N, 11.48 E
At 1507 hours, an Italian aircraft was seen.
Sergio Puccini8 Jun 1942162038.21 N, 11.32 E
At 1620 hours, an Italian aircraft was seen.
Sergio Puccini8 Jun 1942191738.10 N, 11.03 E
At 1917 hours, an aircraft was seen at a distance of 8,000 metres, flying toward the submarine. Alagi dived as the aircraft failed to answer recognition signals.
Sergio Puccini8 Jun 19422119
2123 (e)
38.25 N, 11.05 E
(o) 273° - Trapani - 72 miles.
At 1942 hours, hydrophone noises were detected.

At 2007 hours, Alagi had come to periscope depth and observed a freighter, escorted by a destroyer, steering 170°. As T.V. Sergio Puccini had not been informed of the passage of Italian ships in this area, at that time, he assumed they were enemy ships and prepared for an attack.

At 2020 hours, the range had closed to 5,000 metres and the flag could be seen, but Puccini could not make out the colours. However, the destroyer was recognised to be of typically British design with four guns in single mounts. Twenty minutes later, another destroyer and two more freighters appeared.

At 2119 hours, three torpedoes (533mm) were fired from bow tubes at ranges varying from 2,000 to 3,000 metres. The "senza bolla" (bubbleless) apparatus failed to work properly and the submarine briefly broke surface. After 3 minutes, a loud explosion was heard followed, very quickly, by three fairly close depth-charge explosions.

At 0007 hours on 9th June, the submarine made an enemy report. However, the success was soon turned into tragedy:

Her victim was the destroyer Usodimare (1917 tons) in convoy with the transports Vettor Pisani (6,339 GRT, built 1939) and Sestriere (7,993 GRT, built 1942), the destroyer Premuda and the torpedo-boat Circe steering 180°, 13 knots. It was the presence of the war prize Premuda (ex-Yugoslav, built in England) who had induced Puccini in error. Usodimare had seen a torpedo track and put the helm hard to starboard, but it was too late. The torpedo struck in boiler room no. 3, breaking her in two and she sank in about 20-30 seconds. The torpedo boat Cigno, MAS 563 and MAS 564 were sailed from Trapani to join Circe to look for the survivors. Five officers and 160 ratings were saved, six officers and 115 ratings were missing (the total included 30 passengers).

37.36 N, 09.53 E
(e) 37.00 N, 09.54 E
Since 10th June, MARICOSOM had informed the submarines of ships leaving Gibraltar in an easterly direction, obviously a new attempt to supply Malta.

At 0103 hours, Alagi was informed that this force consisted of a battleship, three destroyers, ten escort vessels and a number of transports. This was rectified at 0735 hours as two aircraft carriers, a battleship, three cruisers and destroyers sighted at 0605 hours in Italian Grid 5801/2, steering 090°, 16 knots. More signals followed.

At 1745 hours, the convoy was sighted through the periscope, in 37°38' N, 09°51' E at distances varying from 10,000 to 20,000 metres.

At 1810 hours, the range was down to 4,000 metres and Alagi now proceeded submerged to close at a depth of 15 metres.

At 1925 hours, a steamer was observed to be hit by a bomb. Five minutes later, a battleship was sighted at a distance of 15,000 metres, steering 335.5° and, at 2045 hours, a cruiser was sighted listing heavily to port. At the same time, to the eastward, an aircraft carrier and a battleship were sighted, followed shortly after by a second aircraft carrier in the process of landing her aircraft at a distance of 7-8,000 metres.

At 2105 hours, two torpedoes (one 533mm and one 450mm) were fired from the stern tubes at a range of 1,500 metres aimed at an aircraft carrier. Due to an error in transmission the 533mm torpedo was fired at an angle of 060° to port instead of to starboard. Alagi now only had one 450mm torpedo left in a forward tube. Both torpedoes missed.

The target was probably the aircraft carrier HMS Eagle with the battleship HMS Malaya, the aircraft carrier HMS Argus and the light cruisers HMS Kenya and HMS Charybdis, screened by destroyers.

Alagi was hunted and depth-charged by the destroyer HMS Marne and then by the minesweeper HMS Speedy who dropped five depth charges. The submarine was claimed probably sunk but escaped damage.
Sergio Puccini6 Jul 1942104034.48 N, 21.32 E
At 1040 hours, an aircraft was sighted at a distance of 10,000 metres and the submarine dived.
Sergio Puccini7 Jul 1942092034.13 N, 24.56 E
At 0920 hours, two aircraft were seen at a distance of 7,000 metres and the submarine dived.
Sergio Puccini8 Jul 1942131534.05 N, 29.19 E
At 1315 hours, a derelict mine was sighted. Alagi turned back to destroy it but could not locate it.
Sergio Puccini12 Jul 19422004
2105 (e)
34.59 N, 35.32 E
At 1935 hours, an illuminated ship was sighted at a distance of 10,000 metres. Twenty minutes later, it was identified as an 8-10,000-ton tanker and shortly after recognised as Turkish. She was steering 200° at 12 knots.

At 2004 hours, two torpedoes (533mm) were fired from bow tubes at a distance of 400 metres. About 20 seconds later, a double explosion occurred.

This was the Turkish Antares (3,723 GRT, 1893) on a trip from Alexandretta to Haifa. She was hit by only one torpedo, in the engine room and, had to be beached in 34°48'50" N, 35°52' E, near Tartus, Syria. Refloated on 27th July, with the assistance of the HM tug Henrietta Moller, HM tug Tientsin, the armed whaler HMSAS Southern Isles and the Free French armed trawler Reine des Flots, she was towed to Iskanderun.
Sergio Puccini14 Jul 1942014533.50 N, 34.59 E
At 0145 hours, a destroyer was sighted. At 0157 hours. Alagi attempted to fire her two stern tubes from about 1,000 meters, but could not get into a good attacking position.
Sergio Puccini14 Jul 1942062533.50 N, 34.59 E
At 0625 hours, a destroyer was sighted steering 040°. A second destroyer was sighted shortly after, on a northerly course and both hunted the submarine until 1230 hours. Alagi rigged for silent running and escaped.
Sergio Puccini16 Jul 1942133534.05 N, 29.18 E
At 1335 hours, an aircraft was seen and the submarine dived.
Sergio Puccini21 Jul 19421458(o) Off Panarca.At 1458 hours, a derelict mine was sighted and destroyed by machine-gun fire.

At 2000 hours, a huge column of smoke was observed through the periscope at about 20,000 metres. Alagi steered toward it.

At 2020 hours, the convoy came under air attack and put a up a fierce antiaircraft barrage. A destroyer was hit by a bomb. T.V. Puccini counted fifteen vessels of the cruisers, destroyers and freighter types.

At 2100 hours, a violent air attack occurred and two steamers were hit by bombs. At that time the submarine was about 3-4,000 metres away.

At 2105 hours, four torpedoes (533mm) were fired from the bow tubes at a distance of 1,500-2,000 metres aimed at a SOUTHAMPTON class cruiser. Alagi heard three explosions as she dived to the bottom at a depth of 90 metres. Puccini believed that no three hits could have hit the cruiser so perhaps a freighter or a destroyer had also been hit.

The light cruiser HMS Kenya was indeed damaged, hit in the bow (three killed, one wounded), a second torpedo passed under and two more narrowly missed her stern and she returned to Gibraltar escorted by four destroyers. In some books, Clan Ferguson was claimed sunk in this attack. She was actually sunk by JU-88s at 0810 hours on the 13th. Survivors of Clan Ferguson (of a crew of 101+13 passengers, 12 were killed) reported to have been torpedoed at 2105 hours (according to Italian authorities), although they claimed to have been hit by a torpedo-bomber, there were no torpedo-bomber attacks at the time. The destroyers HMS Ashanti, HMS Penn and the escort destroyer HMS Derwent hunted the submarine but without success.
Sergio Puccini14 Aug 19420550+At 0550 hours, the conning tower of a submarine was sighted disappearing in the distance.
Sergio Puccini8 Nov 1942115837.24 N, 10.14 E
At 1158 hours, Alagi had been at periscope depth to listen to her radio when suddenly a loud noise was heard and she was shoved to a depth of 24 meters. The submarine then dived to 70 meters. Initially it was believed that the submarine had been bombed by aircraft. Her two periscopes were damaged and there were other damages to the conning tower. Later, TV. Puccini believed that he had collided with another submarine.

Alagi had indeed collided with the submarine Diaspro. She was forced to abort her mission.
Sergio Puccini8 Dec 1942033536.45 N, 05.08 E
At 0335 hours, an MTB was seen and Alagi turned away.
Sergio Puccini10 Dec 19420629(o) Near Cagliari.At 0629 hours, the submarine Turchese, proceeding on one engine to Cagliari, was encountered. They exchanged recognition signals and Alagi overtook her.
Sergio Puccini24 Dec 19420245At 0245 hours, an Axis aircraft was seen and exchanged recognition signals.
Sergio Puccini24 Dec 1942200637.26 N, 08.02 E
(o) Approximately.
At 2006 hours, two explosions were heard. These were torpedoes fired by P 219 on the submarine Mocenigo. Alagi did not sight the submarine.
Sergio Puccini24 Dec 19422230At 2230 hours, an Axis aircraft was seen and exchanged recognition signals.
Sergio Puccini25 Dec 19420725(o) Point C of Cape Spartivento.At 0725 hours, the submarine Giada was encountered and exchanged recognition signals.

At 1900 hours, Alagi was illuminated by a searchlight of an enemy bomber which was sighted at only 500 metres. It flew over the submarine at an altitude of 100 metres and dropped two bombs. Luckily, they missed the stern by 30 to 50 metres. Alagi immediately crash-dived after the explosions.

This was Wellington 'Z' of 179 Squadron. It had detected the submarine at 6 miles and switched the Leigh light when it had closed at half a mile. It dropped four Mark XI Torpex depth-charges from a height of 70 feet and observed one exploding 30 feet from the stern of the submarine. The aircraft circled in the area. When the submarine surfaced at 2000 hours, the aircraft was still there and Alagi had to submerge again.

At 0600 hours, three destroyers were observed through the periscope. They were believed to be the same as those sighted earlier.

At 0613 hours, three torpedoes (533mm, G7e type) were fired from the bow tubes (a fourth misfired) at a range of 700-1,200 metres. After 105 seconds a loud explosion was heard giving a running range of 1,500 metres. Alagi went deep to 70-90 metres and, at 0635 hours, heard two escort vessels followed by two patterns of depth charges, but escaped damage.

The target was actually the light cruiser HMS Cleopatra, proceeding in company with the light cruiser HMS Euryalus, escorted by the destroyers HMS Quilliam and HMS Quail. Cleopatra was damaged by one torpedo hit (twenty-three killed), her speed was reduced to 4.5 knots. However, she soon managed to increase speed to 10 knots and was joined by HMS Euryalus who was within sight. At 0938 hour, she was joined by HMS Eggesford, HMS Seaham, HMS Poole, HMS Oriana and HMS Baltimore (?) [listed in the C. in C. Mediterranean diaries, ADM199/640, TNA, but no such ship existed] and escorted to Malta.
