| 1. | Barbarigo (BO, I.15) | 6 Jun 1940 | 1715 | Naples | 15 Jun 1940 | 1406 | Naples | 1107,4 | Patrolled off Cape Bengut (36°55'27'N, 03°54'00'E, 10 miles from coast). | |
| 10 Jun 1940 | 2358 | (0) Near Algiers. | At 2358 hours, Barbarigo was proceeding on the surface when an enemy escort vessel suddenly appeared from the mist and attempted to ram her. The submarine crash dived. She was at a depth of 12 metres when the vessel was heard to pass nearly above her but she was not depth charged. | |||||||
| 11 Jun 1940 | 0912 | (0) Off Cape Bengut. | At 0912 hours, Barbarigo was at a depth of 22 metres when she was suddenly bombed. To avoid further attacks, she went down to 60 metres and heard the noises of an approaching vessel. This time depth charges exploded at depths deeper than 40 metres as the submarine escaped by going down to 70 metres. Nani, which was in the vicinity, reported hearing explosions at 1025 hours. | |||||||
| 2. | Barbarigo (BO, I.15) | 27 Jun 1940 | 1817 | Naples | 5 Jul 1940 | 1107 | Cagliari | 1473 | Patrolled in 36°00'N, 01°12'W, between Cape de Gata and Cape Falcon. Damaged by A/S forces. | |
| 3 Jul 1940 | 1910-2300 ? (e) | (e) 35° 58'N, 5° 05'W | Barbarigo was at a steady depth of 30 metres using the Rovetto (device used to maintain the trim) when, at 1910 hours, a series of depth charges began to explode. The hydrophones detected the noise of two turbines and the submarine was damaged but escaped by going down to 60 metres and then to 110 metres. At 0030 hours on the 4th, Barbarigo surfaced with two forward torpedo tubes and two aft ready to fight it out, but the hunters were gone. The damage compelled the submarine to abort her patrol. The attacker had been the destroyer HMS Faulknor. | |||||||
| Barbarigo (BO, I.15) | 6 Jul 1940 | 1637 | Cagliari | 7 Jul 1940 | 1120 | Naples | 270 | Passage Cagliari-Naples. | ||
| Barbarigo (BO, I.15) | 18 Jul 1940 | 0920 | Naples | 18 Jul 1940 | 1705 | Naples | 35,3 | Exercises. | ||
| Barbarigo (BO, I.15) | 23 Jul 1940 | 0922 | Naples | 23 Jul 1940 | 1557 | Naples | 33,4 | Exercises. | ||
| 3. | Barbarigo (BO, I.15) | 7 Aug 1940 | 0100 | Naples | 8 Sep 1940 | 1635 | Bordeaux | 4837 | Passed Gibraltar on 14th August 1940. Patrolled between 30°00'N and 33°00'N. Passage from Naples to Bordeaux. Arrived at Bordeaux with 4 x 533mm and 4 x 450mm torpedoes. | |
| 18 Aug 1940 | 0600 | (0) East of Madeira. | At 0600 hours, with visibility down to about 1,000 metres, Barbarigo sighted two vessels, initially believed to be minesweepers. With gunners at action station, the submarine stopped one of them to verify her papers. It proved to be the Spanish Cierto (316 GRT, built 1915) traveling from Barcelona to Cadiz. She was allowed to proceed. During the day, the submarine observed another four fishing vessels. | |||||||
| 19 Aug 1940 | 2005-2022 1911-1925 (e) | 32° 00'N, 13° 00'W (e) 31° 15'N, 13° 02'W | At 1400 hours, a vessel was barely seen on the horizon. Barbarigo moved to intercept at 14 knots. At 1626 hours, the vessel suddenly turned toward the submarine, and she submerged to a depth of 18 metres. At periscope depth, Barbarigo closed at her maximum speed of 7 knots for an hour and then surfaced to attack. However, the vessel was still some 7,000 metres away. As the enemy vessel altered course several times, the submarine was forced to adjust accordingly, but the range had now increased. At 2000 hours, a first round was fired at 12,000 metres. The sea was rough, aiming was difficult and it fell some 2,000 metres from the target. The submarine altered its course to starboard to bring both guns to bear. The range had now dropped to 9,500 metres and a first salvo was fired. At the same time, two flashes were observed from the vessel. She had opened fire with two guns, but they fell quite short. The gun duel lasted 17 minutes, the heavy seas making the situation of the Italian gunners perilous, especially those of the stern gun because the deck there was not as high. The firing range had varied from 9,000 to 10,000 metres. Between 2005 and 2025 hours, the freighter had made repeated SOS signals, identifying her as Aguilar. At 2017 hours, the range has increased to 12,000 metres and, reluctantly, C.C. Ghilglieri decided to break off the action. Barbarigo had fired a total of 30 rounds (23 from the forward gun and 16 from the aft gun). The British Aguilar (3,255 GRT, built 1917) was on a trip from Lisbon to the Canary Islands. She reported being shelled by a submarine of the ARCHIMEDE class at 8,000 to 9,000 yards. She had escaped unscathed. Despite the failure of the action, Ghiglieri expressed his satisfaction for the conduct of his gun crew under his executive officer, T.V. Amedeo Stinchi, who would later take command of the submarine Enrico Toti and then Santorre Di Santarosa. | |||||||
| 21 Aug 1940 | 0800 (0500 local) | 31° 39'N, 16° 55'W | At 0800 hours (it was 0500 hours local time, Italian submarines always used Rome Time), a dark shape was sighted astern in the mist. This was a vessel navigating on a parallel course with Barbarigo. It was observed to be zigzagging, while increasing speed and it now opened fire as the submarine submerged. The shells falling near the submarine did not appear to detonate when they hit the water, leading C.C. Ghilieri to believe that they were armed with delay fuses. The submarine fired one torpedo from a distance of 1,300 metres, followed shortly after by a second one. Their wakes must have been spotted by the enemy vessel, now identified as a single-funnel armed 8-10,000-ton merchant cruiser. Barbarigo was brought down to 90 metres as about twenty depth charges were counted. About 10 minutes after the last explosion, the submarine returned to periscope depth to watch the enemy warship disappear to the southwest (her initial route). | |||||||
| 4. | Barbarigo (BO, I.15) | 9 Oct 1940 | 1330 | Bordeaux | 11 Oct 1940 | 1654 | Bordeaux | 377,5 | The submarine sailed for patrol in zone 11 (between 53°00' N and 55°00' N, and between 23°00' W and 27°00' W) but, while submerged in heavy seas (registering 43° rolls), the acid in her battery spilled out and she was forced to turn back. | |
| 5. | Barbarigo (BO, I.15) | 14 Oct 1940 | 0654 | Bordeaux | 15 Nov 1940 | 1900 | Bordeaux | 5417 | Patrolled west of Ireland (a) between 53°00'N and 55°20'N, and between 17°10'W and 20°10'W (b) between 56°10'N and 57°20'N, and between 17°10'W and 20°10'W. | |
| 17 Oct 1940 | 0958 0950 (e) | 48° 02'N, 9° 25'W (e) 47° 37'N, 10° 52'W | At 0958 hours, an aircraft flying at a altitude of 1,000 metres, was seen at a distance of 7-8,000 metres and the submarine dived to 60 metres. Shortly after, a few explosions were heard in the distance. This aircraft was Sunderland 'D' (N9050) from 10 Squadron (RAAF) piloted by Squadron Leader C.W. Pearce and she was actually attacking Otaria. | |||||||
| 30 Oct 1940 | 1551 | 54° 35'N, 18° 35'W | At 1551 hours, Barbarigo observed masts and a yellow funnel on the horizon and attempted to intercept. The heavy seas (Force 5) restricted her speed to a maximum of 12 knots and after a while the chase was abandoned. | |||||||
| 10 Nov 1940 | 0618+ | 53° 37'N, 17° 40'W | At 0010 hours, Barbarigo was returning home, when information was received from Otaria indicating the presence of an aircraft carrier and three destroyers. She had altered course to intercept when at 0618 hours, the officer of the watch, S.T.V. Angelo Amendolia (who would later command successively Giuseppe Finzi, Alpino Bagnolini and the German-built S 4) observed a shape in the distance to the south. The shape approached rapidly and at 3,000 metres, presented a very narrow target, unsuitable for an attack. The "down the throat" attack, which would later gain a certain popularity with US submarines was not adopted in the Regia Marina. The submarine turned away quickly. The enemy vessel was a destroyer traveling alone and it was quickly realised that she had not spotted Barbarigo. The submarine fired a stern torpedo (533mm, type W 270 G) from a distance of 1,500 metres. After 58 seconds, a hit was heard. A tour of the horizon revealed nothing and the destroyer was believed sunk. Ghilieri noted that this torpedo was the very one used during a test at Fiume in the presence of the Duce on 24th June 1939. | |||||||

| Barbarigo (BO, I.15) | 30 Jan 1941 | 1433 | Le Verdon | 30 Jan 1941 | 1745 | Le Verdon | 51 | Trials. | ||
| Barbarigo (BO, I.15) | 31 Jan 1941 | 1433 | Le Verdon | 31 Jan 1941 | 1815 | La Pallice | 58 | Passage Le Verdon-La Pallice. | ||
| Barbarigo (BO, I.15) | 2 Feb 1941 | 0915 | La Pallice | 2 Feb 1941 | 1600 | La Pallice | 58 | Exercises. | ||
| 6. | Barbarigo (BO, I.15) | 10 Feb 1941 | 1837 | La Pallice | 8 Mar 1941 | 1607 | Bordeaux | 4471,3 | Sailed for patrol west of Ireland in area (a) in zone M, between 55°00'N and 58°00'N, and between 23°00'W and 25°00'W (b) in zone B, between 57°00'N and 58°00'N, and between 15°00'W and 23°00'W (c) south of Zone A, between 58°00'N and 58°45'N, and between 15°00'W and 25°00'W. Met on her return by the German minesweeper M-9 and patrol boats V-401 and V-408 and escorted in. | |
| 12 Feb 1941 | 1055 | At 1055 hours, an aircraft was seen flying westward at a distance of 6,000 metres. The antiaircraft gun crew were at the ready but the aircraft did not notice the submarine. | ||||||||
| 15 Feb 1941 | 1946-1950 | 53° 25'N, 20° 58'W | At 1148 hours, a submarine was observed. It was probably either Bianchi or Otaria. Barbarigo turned away. | |||||||
| 19 Feb 1941 | 1900 | At 1900 hours, the submarine received a signal from BETASOM (1710/19) reporting the sighting of a convoy. Barbarigo was ordered to Italian Grid 4615/66 (between 58°50' N and 59°00' N, and between 11°50' W and 12°00' W) while Marcello was ordered to Grid 4615/46 (between 58°30' N and 58°40' N, and between 11°50' W and 12°00' W). Barbarigo needed to alter course to 033° but was some 325 miles away and the bad weather prevented her from steering this direction. At 1230 hours the next day, she informed BETASOM of her difficulties stating that she could only make 4 knots. | ||||||||
| 20 Feb 1941 | 1310 | At 1310 hours, Barbarigo received a signal from BETASOM that German forces had discovered a large convoy at 1045 hours in position 59°20/30' N, 10°20/30' W steering 320° at 7 knots. She altered course to intercept. | ||||||||
| 21 Feb 1941 | 1045 | 58° 25'N, 16° 55'W (0) Approximately. | At 0300 hours, Barbarigo was ordered to intercept a convoy in 58°25' N, 16°55' W.She had almost reached the position, when, at 1045 hours, she sighted a raft with seven Norwegian survivors, probably from the Norwegian Benjamin Franklin (7,034 GRT, built 1927), a straggler from HX 107 convoy, sunk by U-103 (KK Viktor Schütze) on 19th February in 58°50' N, 16°30' W. The submarine stopped and gave them two boxes of biscuits. The seven men were later picked up by the corvette HMS Pimpernel. At 1310 hours, the submarine was informed of a new position of the convoy and again altered course to intercept. | |||||||
| 23 Feb 1941 | 0725 | 58° 25'N, 16° 55'W (0) Approximately. | At 0725 hours, a shadow was observed at 3,000 metres. Initially, it was taken for a submarine but it proved to be a destroyer and Barbarigo moved away. The submarine was still seeking the convoy reported on 21 February. At 1530 hours, Barbarigo was informed that the convoy was now some 95 miles to the north of her. The next days would be spent to seek it. | |||||||
| 24 Feb 1941 | 1115 | 59° 15'N, 25° 15'W (0) Italian Grid 1880/11 | At 1115 hours, a lone steamer was observed. Barbarigo attempted to intercept it and dived to carry out an attack, but her periscope was defective and nothing could be seen or heard. She surfaced later but the vessel had disappeared. | |||||||
| 25 Feb 1941 | 2000 | At 2000 hours, another signal from BETASOM (1830/25) was received and mentioned another convoy reported at 1400 hours, 450 miles away in Italian grid 2715/25 (56°00' N/56°10' N and 11°40' W/11°50' W) steering 270°, 7 knots. Barbarigo was ordered to Grid 5399/11 (57°00' N/57°10' N and 17°00' W/17°10' W). | ||||||||
| 7. | Barbarigo (BO, I.15) | 5 May 1941 | 1330 | Bordeaux | 30 May 1941 | 1132 | Bordeaux | 4230 | Brief stops at Pauillac and Le Verdon. Patrolled in the Atlantic. Attempted to reach the German battleship Bismarck, but was low on fuel. | |
| 7 May 1941 | 1300 | At 1300 hours, Barbarigo, sailing towards her patrol area, intercepted a signal from(BETASOM 1220/7) to Bianchi, ordering the latter to search for a German aircraft which had ditched in Italian Grid 6005/41 (48°05' N, 15°35' W). Since this was some 120 miles ahead, Barbarigo decided to join the search. She arrived in the area at 0220 hours and searched until 0720 hours without sighting anything and returned to her original course. | ||||||||
| 10 May 1941 | 0320 | 51° 52'N, 19° 40'W | At 1100 hours on 9th May, Barbarigo was informed of a convoy in 54°45' N, 17°25' W, some 300 miles north of her position, and raced to intercept. At 0255 hours on the 10th, S.T.V. Amendolia, who was the officer of the watch, spotted a little shadow bearing 045°. More appeared and it turned out to be a large convoy proceeding to the south. At 0316 hours, a red Very lights was observed and it was feared that Barbarigo had been discovered. A destroyer was closing, the submarine fired a torpedo (450mm) from a stern tube and then observed the warship take evasive action. The torpedo missed. It was assumed that the torpedo track had been sighted. At 0337 hours, Barbarigo made an enemy report and kept trailing the convoy. At 0525 hours, the submarine had lost sight of the convoy and submerged to get a hydrophone bearing. She surfaced again and, at 0551 hours, had regained contact. | |||||||
| 10 May 1941 | 1035 | 51° 15'N, 19° 15'E (0) * Position very approximate. | Barbarigo had reported the convoy at 0545 hours in 51°40' N/51°50' N, 19°10' N/19°20' E steering 180° and was trying to keep contact [so at 1035 hours, Barbarigo must have been about 30-40 miles south of this position]. At 0621+ hours, an aircraft was sighted over the convoy and again at 0814 and 1000 hours but they do not appear to have seen the submarine. However at 1035 hours, two large aircraft were sighted flying low straight toward the submarine which dived to 30 meters. A big shock was felt but there was no explosion (a bomb that did not explode?). Later the noise of two turbines was heard indicating the presence of surface craft. | |||||||
| 11 May 1941 | 1100 | At 1100 hours, BETASOM informed Barbarigo that a large convoy, including an aircraft carrier, two cruisers and destroyers, was in 56°00' N, 17°00' W steering 240°. The submarine altered course to intercept. Two hours later, a new signal from BETASOM amplified it by reporting only one steamer escorted by an aircraft carrier, two cruisers and destroyers and at 1600 hours, the submarine was instructed to resume her course to her patrol position. | ||||||||
| 12 May 1941 | 1259 | At 1259 hours, Barbarigo received a signal from Bianchi indicating that a fast convoy was in 57°25' N, 25°05' W, course 080°, 10 knots. She altered course to intercept. A new signal from Bianchi at 1704 hours, put the convoy closer to Barbarigo, but the speed reported (14 knots) made it unlikely it could be caught up. | ||||||||
| 13 May 1941 | 1900 | At 1900 hours, when Barbarigo was informed by Morosini of a single ship in 54°45' N, 21°05' W course 275°, 14 knots she altered course to intercept. By 0800 hours on the 14th, nothing was found and the chase was abandoned. | ||||||||
| 15 May 1941 | 0239 | 54° 15'N, 21° 58'W | At 1100 hours on the 14th, Barbarigo had received an order to form a patrol line with three other submarines. It was as follows: 1. Bianchi Grid 7626/22 (54°15' N, 18°15' W). 2. Barbarigo Grid 5828/66 (53°55' N, 17°55' W). 3. Morosini Grid 5828/33 (53°25' N, 17°25' W). 4. Otaria Grid 5887/61 (53°05' N, 16°05' W). On her way, at 2226 hours on the 15th, Barbarigo had sighted the dense smoke of a tanker or freighter on fire. At 2244 hours, the smoke was gone but a single vessel was now sighted zigzagging steering between 210° and 270°. After, midnight the course now appeared to be between 260° and 300°. At 0239 hours, the submarine fired a pair of torpedoes (533mm) from the bow tubes at a distance of 1,800 metres. the first torpedo briefly appeared as a surface runner then disappeared completely from sight. The second torpedo had a normal run but missed. The target was the British Manchester Port (5,569 GRT, built 1935), routed independently. Barbarigo was now trying to renew the attack on Manchester Port, by moving ahead to gain a more favourable position. At 0418 hours a torpedo (450mm) was fired from a bow tube at a range of 1,000 metres, but it missed again. C.C. Ghiglieri had intended to fire a pair of torpedoes but, immediately upon firing the first torpedo, he observed that the target had made a sudden alteration of course. He ordered to withhold the firing of the second torpedo. The sudden alteration of course of Manchester Port had also led Barbarigo to turn. At 0420 hours, a pair of torpedoes (533mm) were fired from the stern tubes at a distance of 500 metres. The first torpedo missed under near the bridge area, but the second hit the stern near the mast aft. The vessel appeared to stop her engines and drift slowly to starboard. A large parch of oil was observed. Manchester Port suddenly started her engines and as she moved away she appeared to be dropping a depth charge in her wake. She escaped at high speed. There was no confirmation of her damage. | |||||||
| 16 May 1941 | 0827 0821 (e) | 53° 12'N, 23° 13'W (e) 52° 55'N, 19° 46'W | At 2208 hours on the 15th, following the discovery by Michele Bianchi of a convoy, Italian submarines had received an order (BETASOM 2155/15) to form a new patrol line which was to be as follow: 1. Bianchi Grid 1820/51 (50°05' N, 21°45' W). 2. Barbarigo Grid 1894/61 (50°05' N, 20°55' W). 3. Morosini Grid 1826/61 (50°05' N, 18°55' W). 4. Otaria Grid 1835/61 (50°05' N, 19°55' W). 5. Malaspina Grid 1826/31 (50°05' N, 18°25' W). The chase of Manchester Port had delayed Barbarigo. As she was trying to rejoin the new position assigned, at 0800 hours on the 16th, an aircraft was sighted in the distance. At first, it was not certain if the submarine had been detected, but the aircraft finally turned toward her. At 0817 hours, Barbarigo dived, but the hatch could not be completely shut, despite the efforts by two crew members and at a depth of 20 metres, water was pouring in. Two minutes, later the submarine was forced to surface. On the bridge, with C.C. Ghiglieri, were his executive officer T.V. Pasquale Gigli (destined to command successively Argo, Squalo and Jalea), the gunnery officer S.T.V. Angelo Amendolia (also destined to command submarines) manning the port twin machine guns, gunner Lino Carbonetti at the starboard twin machine guns and helmsman Michele Lubrano. AT 0827 hours, the three-engine aircraft swooped down and at 500 metres, all four machine guns opened fire. The aircraft was Catalina 'B' of 210 Squadron piloted by Flying Officer Coutts and it had been trying to locate a convoy to escort when it had sighted Barbarigo. The submarine dense antiaircraft fire had hit the seaplane, damaging the electrical circuits and this prevented it from releasing the depth charges. However, she strafed the submarine with four burst of machine gun fire. The third and fourth hit the submarine. A fuel tank was perforated by a round, the last burst hit the bridge, Ghiglieri, Amendolia and Carbonetti were slightly wounded by fragments. The submarine crash dived to 60 metres and escaped further damage. | |||||||
| 20 May 1941 | 2016 | 53° 15'N, 25° 40'W (0) Approximately. | At 2016 hours, a steamer was sighted. Barbarigo attempted to close, but lost it in a rain squall. | |||||||
| 22 May 1941 | 1435 | At 1435 hours, a steamer was sighted but Barbarigo could not catch up. | ||||||||
| 24 May 1941 | 2107 | At 2107 hours, an enemy cruiser was sighted. Barbarigo dived immediately, but could detect her with her hydrophones. She did not make an enemy report, as she had been struggling in heavy seas for the last three days and had no accurate fix. | ||||||||
| 27 May 1941 | 1200 | At 1200 hours, Barbarigo was returning to base through 51°30' N, 22°30' W and 45°30' N, 15°30' W, when she was ordered by BETASOM to attack the enemy warships engaging the battleship Bismarck in Italian Grid 5587 (centered on 47°30' N, 16°30' W). She altered course to the northeast, but the bad weather prevented her from making good progress. At 1330 hours, she was informed that the Bismarck was sunk. | ||||||||
| 27 May 1941 | 1356 | 46° 45'N, 17° 25'W | At 1356 hours, two British cruisers were seen in the mist, course 210°, 20 knots. The submarine dived, but her hydrophones were defective and were not repaired until 1651 hours, so no further contact was made. | |||||||
| 28 May 1941 | 1100 | At 1100 hours, BETASOM ordered Barbarigo to search for the Bismarck's survivors in Italian Grid 6087/21 (48°05' N, 16°15' W). The submarine did not comply as she was 190 miles away and Ghiglieri believed that many ships were already participating in the search, which was not the case. He was later criticized for not having made the attempt. | ||||||||
