2 | Crepas, Alberto | 31 Jul 1940 | 2225 | La Maddalena | 1 Aug 1940 | 1518 | Cagliari | 175,6 | Sailed with Scirè and Neghelli for a patrol in 37°40'N, 06°20'E. Made a brief stop at Cagliari, to pick up her sailing orders before proceeding for patrol. | |
2b | Crepas, Alberto | 1 Aug 1940 | 1542 | Cagliari | 10 Aug 1940 | 2237 | La Maddalena | 1167 | Patrolled south of the Balearic Islands in position 37°49'N, 06°20'E. Part of a barrage line involving six other boats: Scirè, Neghelli, Turchese, Medusa, Axum, and Diaspro. MARICOSOM had ordered a screen on two lines (three and four boats respectively) north of Cape Bougaroni (06°20’ E meridian). The two lines were 10 miles apart and each submarine was positioned 20 miles from the next one. The second day into the mission, Medusa had to return to base and was later replaced by Manara. Uneventful. | |

3 | Crepas, Alberto | 2 Oct 1940 | 1400 | La Spezia | 24 Oct 1940 | 1320 | Bordeaux | 3038 | Passage from La Spezia to Bordeaux. Passed Gibraltar on 8th October. Patrolled in area between 36°00'N and 36°30'N, and between 09°04'W and 09°42'W. The submarine experienced defects in two forward tubes and one stern tube. Escorted in by M-9, M-13 and M-21. | |
12 Oct 1940 | 0940 0800 (e) | (e) 36° 50'N, 10° 00'W (0) 260° - Cape St. Vincent - 50 miles. | At 0846 hours, a smoke was observed. At 0900 hours, the submarine dived and recognised it as a 4,000-ton armed vessel on a 180° course. At 0940 hours, a single torpedo (533mm, type W) was fired from a bow tube at a distance of 600 metres. It missed. This was the armed trawler HMT Cape Barracouta who reported the attack. Bad weather prevented the submarine from a surface action. | |||||||
12 Oct 1940 | 1434-1545 | 36° 00'N, 9° 30'W (0) Approximately. | At 1434 hours, the Portuguese trawler Estrella Do Norte (325 GRT, built 1919) was ordered to stop, but was allowed to proceed after examination. | |||||||
4 | Crepas, Alberto | 22 Nov 1940 | 1130 | Bordeaux | 12 Dec 1940 | 1900 | Le Verdon | 3075 | Patrolled in the Atlantic between 53°20'N and 54°20'N, and between 17°00'W and 20°00'W. | |
1 Dec 1940 | 0449 0355 (e) | 54° 05'N, 16° 55'W (e) 54° 40'N, 15° 20'W | Argo was proceeding on the surface when, at 0449 hours, the officer of the watch sighted a shadow which was at first taken for a submarine. She took an intercepting course and when it was realised that it was a destroyer, a single torpedo (533mm) was fired from a bow tube at distance of 600 metres and scored a hit after 40 seconds. The submarine turned and tried to finish her off with a stern shot (450mm), but missed. A second stern shot (533mm) followed and was claimed to have hit (it had not). This was the destroyer HMCS Saguenay. With HMS Highlander, she had been escorting convoy HG.47 but had temporarily lost contact with the convoy. She had sighted the submarine at 800 yards and fired two rounds which missed before the torpedo hit the forward part on the port side. Twenty-one were killed. At 0700 hours, HMS Highlander arrived on the scene to assist her and took off five officers and eighty-five ratings. The remaining crew (five officers and fifty-three ratings) managed to bring Saguenay to port stern first. The tugs Englishman, Salvonia [she was later diverted to assist the armed merchant cruiser HMS Forfar] and Schelde, and the A/S trawlers HMT Foxtrot, HMT Stella Polaris and HMT Sphene were sailed to her assistance. She managed to reach Barrow in Furness towed by the tug Schelde at 1615 hours on 5th December. | |||||||
2 Dec 1940 | 0610 | 54° 53'N, 18° 28'W | At 0610 hours, the sound of gunfire was heard followed by what appeared to be a torpedo hit at a distance of 4,000 metres. Possibly the British Dunsley (3,862 GRT, built 1929) from convoy HX.90, damaged by gunfire at 0606 hours in 54°41' N, 18°41' W by U-47 (KK Günther Prien). | |||||||
2 Dec 1940 | 0825 0932-1350 (e) | 54° 36'N, 18° 26'W (e) 54° 37'N, 18° 26'W | At 0800 hours, a small steamer or perhaps a convoy escort was observed, possibly collecting survivors. The submarine stopped its diesels and proceeded on its electric motors to avoid being heard. At 0825 hours, the submarine fired a torpedo (533mm) from no.4 tube at a range of 500 metres, but it appeared to veer to the right and missed. The submarine dived to a depth of 80 metres. At 0919 hours, "Hastig" was heard (sic, ASDIC), immediately followed by depth charges. From 0912 hours to 1437 hours, Argo was subjected to a systematic hunt by two destroyers and counted 96 depth charges, but suffered practically no damage. At 2045 hours, the submarine surfaced with the gun crew at action station, but the horizon was empty. The target had been the destroyer HMCS St. Laurent and together with HMS Viscount, they had hunted the submarine dropping 81 depth charges. HMCS St. Laurent had indeed picked up survivors from Conch and was looking for those of the armer merchant cruiser HMS Forfar when the attack occurred. Although both destroyer captains doubted the result of their attacks, the U-boat Assessment Committee had concluded the U-boat "probably sunk". | |||||||
4 Dec 1940 | 1255 | 54° 00'N, 18° 00'W (0) Very approximately. | At 1255 hours, a Sunderland aircraft was sighted at 2,000 metres. Argo fired six pans of machine gun rounds before diving to a depth of 60 metres. No explosions were reported. | |||||||
5 Dec 1940 | 0339 0220 (e) | 54° 14'N, 18° 08'W (e) 54° 00'N, 17° 30'W (0) Z | At 0339 hours, the officer of the watch suddenly sighted a dark shape. A torpedo was immediately fired at a distance of 500 metres at a 12,000-ton two-funnel vessel. The torpedo hit after 35 seconds under the first funnel. A second explosion followed, attributed to a boiler and she sank. This was the steamer Silverpine (5,066 GRT, built 1924) in ballast and detached from convoy OB.252 bound from Glasgow to New York. Thirty-six were killed. Nineteen survivors were picked up by HMS Harvester at 0900 hours in 57°00' N, 17°30' W. The submarine was later hunted by HMS Harvester. Starting at 0412 hours, Argo reported three patterns of eight depth charges each. | |||||||
11 Dec 1940 | 1545 | (0) ? | A big wave covered the bridge and carried over the First Officer T.V. Alessandro de Santis. The submarine turned back and closed to about 20 metres from the unfortunate officer. Sotto Capo Cannoniere [Petty Officer (Gunner)] Lorenzo Ciapetti bravely offered to jump in the water to reach him with a life saver. He closed to about 8-10 metres before De Santis disappeared and was no longer seen. Ciapetti was recovered and the submarine resumed course. For his bravery, Lorenzo Ciapetti was awarded the Medaglia d'Argento al valore militare (Silver Medal). | |||||||
Crepas, Alberto | 25 Jan 1941 | Le Verdon? | 25 Jan 1941 | Date? | Le Verdon? | According to the KTB of 2.MSFL, Argo made a sortie on this date, escorted by M-12 and M-21. Italian documents do not show such a sortie. She may have been mistaken for Dandolo who sailed on that day. | ||||
Crepas, Alberto | 21 Feb 1941 | 1508 | Bordeaux | 21 Feb 1941 | 1950 | Le Verdon | 47 | Passage Bordeaux-Le Verdon. | ||
Crepas, Alberto | 22 Feb 1941 | 1502 | Bordeaux | 22 Feb 1941 | 1745 | Le Verdon | 10 | Trials. | ||
Crepas, Alberto | 23 Feb 1941 | 1200 | Le Verdon | 24 Feb 1941 | 0030 | La Pallice | 62 | Passage Le Verdon-La Pallice with the submarine Brin escorted by the German minesweepers M-2, M-6 and M-21 and Sperrbrecher 16. | ||
Crepas, Alberto | 25 Feb 1941 | 0840 | La Pallice | 25 Feb 1941 | 1653 | La Pallice | 53 | Exercises. | ||
5 | Crepas, Alberto | 28 Feb 1941 | 1705 | La Pallice | 30 Mar 1941 | 1142 | Bordeaux | 4270 | Sailed for patrol between 59°30'N and 53°00'N, and between 13°00'W and 25°00'W. Then went into dry-dock for long refit. | |
1 Mar 1941 | 1300 | 45° 55'N, 8° 30'W | At 1300 hours, an unidentified aircraft was sighted at 6,000 metres and circled the submarine as close as 1,000 metres. Argo made the recognition signal but was not answered. The aircraft disappeared and the submarine dived. | |||||||
5 Mar 1941 | 1400 | 47° 10'N, 11° 40'W | At 1400 hours, a submarine of the BIANCHI class was observed on 120° course. Argo turned away. | |||||||
7 Mar 1941 | 1400 1301 (e) | 53° 35'N, 16° 50'W (e) 53° 20'N, 18° 50'W | At 1400 hours, an aircraft was sighted at 6,000 metres. When it had closed at 1,500 metres, Argo made a recognition signal, receiving the correct counter signal. At a range of 800 metres, the aircraft was identified as a Sunderland and the submarine opened fire with her machine guns. Argo managed to keep the aircraft at bay until she dived at 1415 hours. The aircraft was Sunderland 'H' of 210 Squadron and did not carry out an attack. The presence of HMS Taku in the area probably inhibited the pilot from pressing home an attack. | |||||||
10 Mar 1941 | 1830 | 57° 37'N, 23° 55'W | At 1830 hours, an antisubmarine vessel was sighted at 4,000 metres, the submarine dived and was not detected. | |||||||
11 Mar 1941 | 1220 | 57° 15'N, 24° 36'W | At 1220 hours, a 4-5,000-ton vessel was sighted at 6-7,000 metres on a 060° course. The submarine maneuvered around it intending to attack in the evening, but at 1355 hours lost contact. | |||||||
27 Mar 1941 | 1300 | 47° 20'N, 9° 20'W | At 1300 hours, an aircraft was sighted coming from the south. When the range had dropped to 1,000 metres, the submarine made the recognition signal which was not answered. At a distance of 800 metres, it was recognised as a Sunderland and two rounds were fired and the aircraft disappeared to the north. T.V. Crepas was not satisfied of his antiaircraft armament of two Breda machine guns and suggested that it must be increased to four. | |||||||
6 | Crepas, Alberto | 19 May 1941 | 1345 | Bordeaux | 14 Jun 1941 | 1045 | Bordeaux | 3367 | Patrolled off Portugal and west of the Strait of Gibraltar between 35°40'N and 36°20'N, and between 07°40'E and 06°30'W. | |
20 May 1941 | 1510 | 44° 18'N, 3° 19'W | 1510 hours, a German bomber was sighted and recognition signals exchanged. | |||||||
21 May 1941 | 1721 | 44° 28'N, 8° 15'W | At 1721 hours, an aircraft was sighted at 4,000 metres and came as close as 2,000 meters. It did not respond to recognition signals and flew away in a southerly direction. | |||||||
27 May 1941 | 0100 | 35° 45'N, 8° 56'W | At 2300 hours on 26th March, Argo was informed by BETASOM (signal of 2215/26) of a battleship, an aircraft carrier and a cruiser sighted at 1600 hours in Italian Grid 0326/22 [Force H], probably proceeding to Gibraltar. Argo, Marconi, Veniero and Mocenigo were ordered to intercept. At 0100 hours, an illuminated vessel was seen on a 200° course. It was apparently neutral and the submarine let her go. | |||||||
29 May 1941 | 1630+ | 35° 58'N, 6° 48'W (0) Italian Grid 1510/66. | The submarine heard H.E. at 1630 hours and shortly after sighted a convoy of ten steamers, escorted by three destroyers, steering 240°. The submarine surfaced at 1740 hours and made an enemy report. One diesel had broken down and Argo could not maintain contact. | |||||||
30 May 1941 | 0730-2252 | 35° 58'N, 6° 48'W (0) Approximately. | From 0730 to 2252 hours, the submarine was subjected to a systematic hunt and counted 91 depth charge explosions. However, Argo was undamaged and surfaced at 2330 hours and escaped to the westward. | |||||||
31 May 1941 | 1230-1546 | 35° 58'N, 6° 48'W (0) Approximately. | From 1230 to 1546 hours, the submarine was subjected to a systematic hunt by three vessels and counted fifteen depth charge explosions. However, Argo was undamaged. | |||||||
4 Jun 1941 | 0415 | 36° 32'N, 8° 00'W | At 2310 on 3rd June, the submarine received orders from BETASOM (1950/3) to move to Grid 7562/32 for a period of 48 hours. At 0415 hours, an enemy warship was sighted and perhaps two more. The submarine dived to avoid detection. At 2350 hours on the 5th, the submarine received a signal from BETASOM reporting a convoy at 1830 hours in Grid 8511/11, course 090°, 8 knots. She was ordered to intercept at 1600 hours on the 6th in Grid 8562/13. | |||||||
6 Jun 1941 | 0750 | 37° 10'N, 9° 25'W | At 0750 hours, a submarine was sighted but she apparently took avoiding action. Between 1255 and 1800 hours, Argo reported being hunted and hearing fifteen depth charges. | |||||||
7 Jun 1941 | 1230 | 37° 11'N, 10° 22'W | At 1230 hours, a steamer was observed to have sailed from Lisbon and taken a 220° course. This proved to be the Brazilian Bagé (8,235 GRT, built 1912) and she was left alone. | |||||||
8 Jun 1941 | 1540 | (0) Off Lisbon. | At 1540 hours, the submarine was hunted and dived to 60 metres. Nine explosions were heard and Argo went to 80 metres. Four explosions followed at 1630 hours and two more at 1700 hours. | |||||||
11 Jun 1941 | 1845 | 43° 30'N, 10° 45'W | At 1845 hours, two corvettes were sighted but avoided. | |||||||
12 Jun 1941 | 1500 | 44° 10'N, 8° 20'W | An unidentified aircraft attempted an attack but was repulsed with the submarine expending four magazines of machine gun rounds. | |||||||
Crepas, Alberto | 12 Sep 1941 | 0905 | Bordeaux | 12 Sep 1941 | 1330 | Le Verdon | Passage Bordeaux-Le Verdon. | |||

Crepas, Alberto | 13 Sep 1941 | 0900 | Le Verdon | 13 Sep 1941 | 1710 | La Pallice | Diving tests at Le Pertuis d'Antioche. At a depth of 20 metres water infiltration was observed that could not be controlled. The submarine surfaced and a fuel leak was also seen. The submarine proceeded to La Pallice to carry out repairs. | |||
Crepas, Alberto | 15 Sep 1941 | 0800 | La Pallice | 15 Sep 1941 | 1755 | La Pallice | Diving tests to 40 metres. The infiltrations were verified to have stopped. | |||
7 | Crepas, Alberto | 16 Sep 1941 | 0905 | La Pallice | 24 Sep 1941 | 1600 | Bordeaux | 1895 | Sailed from Le Verdon for Cagliari. At 1000 hours she had reached in 39°12'N, 13°00'W and dived and several defects were noted including the gyrocompass. The submarine had to navigate with an ordinary compass and At 2200 hours surfaced. T.V. Crepas took the decision to turn back [mileage since Bordeaux on 12th September]. She was under repairs from 25th September to 7th October. | |
Crepas, Alberto | 8 Oct 1941 | 0830 | Bordeaux | 10 Oct 1941 | La Pallice | Passage Bordeaux-La Pallice. | ||||

13 Oct 1941 | 1030 0939 (e) | 45° 32'N, 8° 08'W (e) 45° 48'N, 8° 07'W | At 1030 hours, Argo came under attack by a Catalina aircraft. This was actually Hudson 'I' (AM553) of 233 Squadron piloted by Flying Officer Haigh. One bomb was dropped but missed the submarine by 100 metres. The submarine remained on the surface firing 51 100mm rounds and 478 13.2mm rounds to keep the aircraft at bay. Three more bombs were dropped but missed the submarine's bow by 50 metres. At 1330 hours, the aircraft finally flew away and the submarine submerged. BETASOM requested from the BdU that aircraft cover be provided and two Me 110 were promised, but finally did not take off although a German U-boat was sent to her assistance. | |||||||
20 Oct 1941 | 0255 | (0) 153° - Malabata - 6 miles. | At 0255 hours, a submarine chaser was sighted. The submarine submerged and crossed the Strait of Gibraltar without further incidents. | |||||||

9 | Contreas, Giulio | 2 Apr 1942 | 1955 | Naples | 22 Apr 1942 | 2305 | Cagliari | 1796,5 | Patrolled between 36°20'N and 36°40'N, and between 01°40'W and 00°40'E, southeast of Cape de Gata, southeast of Cape Palos, West of Cape Falcon to attack traffic to and from Gibraltar. On 13th April, was ordered in Grids 6366 and 4566. One of the longest Mediterranean patrol for an Italian submarine. | |
10 Apr 1942 | 0605 | 36° 39'N, 0° 40'E | At 0605 hours, a cruiser or large destroyer was sighted at 3,000 metres. The submarine maneuvered to pass ahead of the enemy vessel to fire the stern tubes at less than 1,000 meters, but C.C. Contreas believed he had been detected and went down to 120 meters. No counterattack followed. | |||||||
15 Apr 1942 | 0224 | At 0224 hours, the Portuguese schooner Pádua (665 GRT, built 1925) was sighted at 1,000 metres. | ||||||||

10 | Gigli, Pasquale | 20 May 1942 | 1800 | Cagliari | 30 May 1942 | 1100 | Cagliari | 1165 | Patrolled area between 37°20'N and 37°40'N, and between 02°20'E and 03°00'E, northwest of Cap Caxine (Algeria) to attack Malta traffic. On 28th May was ordered to move 50 miles east and 10 miles north. Sustained three aerial attacks and was badly damaged. | |
27 May 1942 | 2350 | 37° 40'N, 2° 10'E (e) 37° 38'N, 2° 05'E | At 2350 hours, a lookout spotted an aircraft making a run from the stern under the moonlight. Four depth charges straddled the submarine, one actually hitting the forward port hydroplane, and injuring one man in the forward torpedo room. The torpedo tube caps had been opened and three torpedoes had to be ejected. The submarine remained on the surface firing off its antiaircraft machine guns and 19 100mm rounds at the aircraft identified as a Sunderland, which now circled at a distance of 1,000 to 1,500 metres. This was actually Catalina 'C' (AJ162) of 202 Squadron based at Gibraltar and piloted by Flight Lieutenant R.Y. Powell. It had detected the submarine by radar at 6-7 miles and sighted the submarine at 300 yards, and identifying at as of the Italian BALILLA class. It had strafed the submarine releasing eight depth charges from a height of only 50 feet. | |||||||
28 May 1942 | 1423 1415-1642 (e) | 37° 46'N, 2° 47'E (e) 37° 59'N, 2° 08'E | At 1355 hours, an aircraft was sighted coming from the stern at a distance of 6,000 metres. T.V. Gigli elected to fight on the surface. This was Sunderland "R" of 10 Squadron (RAAF) piloted by Flight Lieutenant H.G. Pockley. At 1423 hours, it dropped a salvo of four depth charges from a height of 50 metres and strafed the submarine. The submarine was near-missed. The aircraft came for a second attack and at 1427 hours dropped another four depth charges (others failed to release) and was met by heavy flak, it took several hits but suffered minor damages. In all Argo fired 17 rounds of 100mm and 1,200 round of 13.2mm but a depth charge lodged in the bow section but failed to explode. It prevented the submarine from diving from fear it would detonate and she made an SOS. The Sunderland came for a third attack and dropped another three depth charges. At 1830 hours, the Sunderland left the scene and was replaced by Hudson 'V' of 233 Squadron. | |||||||
28 May 1942 | 1820 1841 (e) | 37° 55'N, 3° 30'E (e) 38° 09'N, 3° 27'E (0) Approximately. | At 1820 hours, an aircraft attacked Argo with four depth charges. This was Hudson "V" (V9168) of 233 Squadron, piloted by Flying Officer Paisey. The charges failed astern. The submarine was strafed but maintained heavy antiaircraft fire. She was believed to have been damaged and the light cruiser HMS Charybdis and the destroyers HMS Westcott and HMS Wrestler were sailed from Gibraltar at 2000 hours on the 28th but failed to locate her. | |||||||
30 May 1942 | 1030 | (0) Anchored at buoy off entrance of Cagliari. | Argo had anchored at 0715 hours off Cagliari as she had been told not to enter the habour because of an unexploded bomb. At 1030 hours, the submarine was visited by Admiral Legnani and Gruppo commander C.F.Criscuolo who congratulated the crew for their escape. | |||||||

11 | Gigli, Pasquale | 13 Sep 1942 | 1709 | Cagliari | 28 Sep 1942 | 1158 | Cagliari | 1320,5 | Sailed with Alabastro via (1) Point C (2) 37°08'N, 04°10'E (3) 37°08'N, 02°40'E for a patrol off Algiers between 37°00'N and 37°30'N, and between 02°00'E and 02°20'E. | |
14 Sep 1942 | 1419 | 37° 30'N, 5° 14'E | At 1419 hours, Argo sighted a submarine believed to be Alabastro who did not return from patrol. | |||||||
14 Sep 1942 | 1610 | 37° 24'N, 4° 58'E | At 1610 hours, Argo sighted a Sunderland and crash-dived. This was probably the same which attacked Alabastro a few minutes later. | |||||||
14 Sep 1942 | 2000 | 37° 21'N, 4° 50'E | At 2000 hours, an illuminated vessel was sighted proceeding to Algeria. It was probably a Vichy ship and was left alone. | |||||||
15 Sep 1942 | 0502 | 37° 14'N, 2° 38'E | At 0502 hours, a submarine was sighted on a parallel course and Alabastro and Argo dived to avoid it. There is little doubt that Alabastro had been sunk the previous day. No other submarine appears to have operated in this area. | |||||||
24 Sep 1942 | 2201 | 37° 14'N, 2° 15'E | At 2201 hours, a Sunderland was sighted and Argo dived four minutes later. | |||||||

13 | Gigli, Pasquale | 7 Nov 1942 | 0440 | Cagliari | 13 Nov 1942 | 1715 | Cagliari | 812 | Sailed for a patrol between 37°50'N and 38°00'N, and between 06°40'E and 07°10'E on an E/W axis. At 0800 hours on the 8th, she was ordered to move 60 miles to west. However, at 2100 hours the same evening, she was ordered to the Gulf of Philippeville, between 37°20'N and the Algerian coast, and between 06°10'E and 07°10'E. During the evening, she was ordered to the Bay of Bougie. | |
8 Nov 1942 | 0340-0445 | 37° 56'N, 7° 00'E | Between 0340 and 0445 hours, about fifty flashes were sighted to the south (probably from Bone) on the horizon. The submarine dived at 0445 and continued her observations from periscope depth. | |||||||
8 Nov 1942 | 0805 | 37° 53'N, 6° 35'E | At 0805 hours, a submarine was seen and was assumed to be Italian. Argo refrained from attack. | |||||||
8 Nov 1942 | 0908 | 37° 54'N, 6° 28'E | An unidentified aircraft was seen and the submarine dived. | |||||||
8 Nov 1942 | 0929 | 37° 54'N, 6° 28'E | An unidentified aircraft was seen. It was probably Italian. | |||||||
8 Nov 1942 | 0959 | 37° 56'N, 6° 30'E | An unidentified aircraft was seen and the submarine dived. | |||||||
8 Nov 1942 | 1935 | 38° 01'N, 6° 14'E | At 1935 hours, an unidentified aircraft with a red light was observed. At 2125 hours, the submarine was ordered to the Gulf of Philippeville, which it it reached at 2130 hours on the following evening, but nothing was sighted. | |||||||
10 Nov 1942 | 0250 | 37° 05'N, 6° 42'E | At 0250 hours on 10th November, an unknown submarine was seen, but it was probably Italian and no action was taken. | |||||||
10 Nov 1942 | 0450 | 37° 05'N, 6° 39'E | At 0450 hours on 10th November, an unknown submarine was seen but it was probably Italian and no action was taken. | |||||||
11 Nov 1942 | 0814 | 37° 10'N, 6° 44'E | At 0814 hour on 11th November 1942, the submarine was at periscope depth when an aircraft was sighted but no action was taken. | |||||||
12 Nov 1942 | 0405 | (0) Bay of Bougie. | At 0405 hours on 12th November, a steamer on fire and screened by three corvettes was observed moving slowly at 2,000 metres. Argo was in very shallow waters (ca. 20-25 meters) and her echo-sounding gear had just broke down. At 0424 hours, she had closed the steamer and prepared to attack with her bow torpedoes, when a second overlapping steamer appeared at a distance of 3-4,000 meters, the submarine then maneuvered to get into a good attacking position. | |||||||
12 Nov 1942 | 0601 0505 (e) | 36° 42'N, 5° 10'E | At 0601 hours on 12th November, Argo observed two overlapping ships at a distance of 1,000-2,000 metres in the Bay of Bougie. Four bow torpedoes (533mm, G7e) were fired and three hits were claimed. The targets were the auxiliary antiaircraft ship HMS Tynwald (2,376 tons, built 1941) standing by the monitor HMS Roberts who was damaged by two bombs the previous day. In fact, two torpedoes had struck HMS Tynwald and she quickly sank in 7 fathoms of water. Three officers and twenty-one ratings were killed, three ratings wounded. Survivors were picked up by HMS Roberts and HMS Samphire (twenty officers and 175 ratings were repatriated on Strathnaver and Ocean Volga). The attack had been a very daring one, as there were some fourteen escort vessels in the anchorage. Karanja was sunk by air attack at about the same time. Shortly after, Argo turned and fired her two stern torpedoes (533mm, G7e) at the same targets from a distance of 2,000 metres. One hit was claimed but they had both missed. The target was probably the monitor HMS Roberts next to the sinking HMS Tynwald. The submarine managed to reach deep waters without interference. At 2325 hours, she received the order to return to base. Some sources have attributed the sinking of the troopship Awatea to her, but she was damaged by three bomb hits at 1700X hours on the 11th in position 310; - Cape Carbon - 2 miles and had been abandoned. At 1300 hours on the 12th, five Italian torpedo bombers attacked the anchorage and one hit the Tynwald, but she had already been abandoned. A surfaced submarine was sighted. HMS Spey and four escorts (including ORP Blyscawica, HMS Rother, probably HMS Bramham? and ?) went on an A/S hunt but, on the way, were attacked by aircraft and all were damaged by near misses and suffered some casualties. | |||||||
14 | Gigli, Pasquale | 16 Nov 1942 | 1840 | Cagliari | 24 Nov 1942 | 1209 | Cagliari | 718 | Patrolled between 37°00'N and 37°20'N, and between 07°00'E and 07°20'E, on a barrage line with Avorio. During the night of 19/20th November, she was ordered to reconnoitre Philippeville (Skikda). | |

30 Dec 1942 | 2123 | 37° 13'N, 4° 29'E | At 2123 hours on 30th December, a torpedo boat was observed at a distance of 1,500 metres and appeared to be proceeding at 14 knots to ram the submarine. Argo dived but was not attacked. | |||||||
1 Jan 1943 | 0434 | 37° 16'N, 4° 33'E | At 0434 hours on 1st January 1943, two steamers, escorted by three corvettes, were observed at a distance of 5-6,000 metres. The submarine closed to attack, but a corvette turned toward her and she was forced to dive at 0440 hours. | |||||||
2 Jan 1943 | 0007 | 37° 24'N, 5° 22'E | At 0007 hours, a warship, which could not be properly identified, was seen at a distance of 1,500 metres. It could have been a submarine, a submarine chaser similar to the Italian Albatros or even an MTB. The submarine readied her bow tubes but the target turned away. | |||||||
7 Jan 1943 | 0059 | 37° 03'N, 5° 12'E | At 0059 hours on 7th January 1943, two cruisers, one of them of the SOUTHAMPTON class, and four destroyers were seen at a distance of 2,000 metres on a 270° course. The submarine fired a salvo of four torpedoes (533mm) from her bow tubes and claimed one hit, but this was not confirmed. Four depth charges were dropped but Argo escaped by going down to a depth of 100 metres. | |||||||

19 Jun 1943 | 0220 | 37° 16'N, 5° 19'E | A Sunderland aircraft circled the submarine. The gun crew were readied to open fire on the aircraft, but an opportunity arose and Argo dived without being attacked. | |||||||
19 Jun 1943 | 0902 | 36° 54'N, 5° 25'E (0) 246° - Cape Carbon - 16 miles. | At 0656 hours on 19th June, H.E. were heard and the submarine came to periscope depth and sighted a patrol vessel. T.V. Giliberti assumed that the vessel was perhaps patrolling ahead of a convoy in the Gulf of Bougie and submerged to a depth of 50 metres for a listening watch. At 0812 hours, noises were heard. It was a convoy steering 105°, entering the anchorage. At 0902 hours, four torpedoes from the bow tubes were fired a 7,000-ton freighter from a distance of 3,000 metres. Three hits were heard and the submarine dived to a depth of 110 metres, but there was no immediate reaction from the enemy. In fact, no hits were confirmed. | |||||||
