1 Sep 1940 | 0610 0720 (e) | At 0610 hours, a Sunderland was sighted at a short distance coming head on. It passed Diaspro on the starboard side and T.V. Marino Salvatori ordered the submarine to dive. As she did so, the aircraft made a stern attack, strafing her. The submarine reached a depth of 40-50 metres and proceed westward. At 0740 hours, five bombs were heard, one of them loudly ahead, the others more distant on both sides. Corallo went down to 70-80 metres. Hydrophone noises were heard and the submarine moved away from them. At 0854 hours, an explosion was heard. At 1035 hours, five explosions were heard astern. At 1220 hours, three explosions was heard to starboard. At 1707 hours, a bomb was heard ahead and finally at 1725 hours five bombs were heard astern. The attacking aircraft was a Swordfish from the aircraft carrier HMS Ark Royal. | ||||||||

6 | Salvatori, Marino | 15 Nov 1940 | 1841 | Cagliari | 19 Nov 1940 | 1541 | Cagliari | 542 | Patrolled north of Cape Bougaroni on parallel from 37°20'N, 06°00'E to 05°00'E. | |
17 Nov 1940 | 1030 | (0) North of Cape Bougaroni. | At 1030 hours, a British destroyer of the "H" class was sighted at a distance of 7,000 metres, steering 080°, 12 knots. Diaspro could not close the range for an attack. | |||||||
7 | Salvatori, Marino | 26 Nov 1940 | 0138 | Cagliari | 2 Dec 1940 | 1353 | Cagliari | 702 | Patrolled southwest of Sardinia, from 38°20'N, 08°40'E to 10 miles south, on a patrol line with Axum, Aradam and Alagi. | |

8 | Borghese, Junio Valerio | 21 Jan 1941 | 1525 | Cagliari | 22 Jan 1941 | 2335 | Cagliari | 201,7 | Patrolled south of Sardinia to replace Corallo who had to interrupt her mission because of defects. Early return because Diaspro also had defects. | |
9 | Borghese, Junio Valerio | 9 Feb 1941 | 0057 | Cagliari | 11 Feb 1941 | 1226 | Cagliari | 294,5 | Patrolled east of La Galite from 37°30'N, 09°50'E to 20 miles northward. Borghese was criticised by Rear-Admiral Oliva for submerging from 2400 hours to 0155 hours on the 10th and ignoring instructions issued on 20th January to Mediterranean submarines to operate on the surface during dark hours for at least the first 15 minutes of each hour. | |

10 | Dotta, Antonio | 21 May 1941 | 0440 | Cagliari | 23 May 1941 | 1120 | Cagliari | 314 | Patrolled east of La Galite in 37°40'N, 09°50'E, with Corallo in an adjacent area, to intercept Force H reported to have sailed from Gibraltar. Uneventful. Sighted only an aircraft and heard H.E. | |
11 | Dotta, Antonio | 5 Jun 1941 | 2315 | Cagliari | 12 Jun 1941 | 1150 | Cagliari | 824,5 | Patrolled in Western Mediterranean from 37°54'N, 08°00'E on course 265° to 06°00' then (between Sardinia and Bone) against an expected convoy from Gibraltar. Uneventful. | |
12 | Dotta, Antonio | 2 Jul 1941 | 2119 | Cagliari | 12 Jul 1941 | 1200 | Cagliari | 991,5 | Patrolled in Western Mediterranean within 20 miles from 37°20'N, 02°40'E, with Corallo in an adjacent area, against an expected force from Gibraltar Uneventful. | |
13 | Dotta, Antonio | 16 Jul 1941 | 1725 | Cagliari | 19 Jul 1941 | 0805 | Cagliari | 429,5 | Patrolled in Western Mediterranean on parallel between 37°30'N and 37°40'N, 06°00'E to 05°00'E, with Alagi in an adjacent area, against an expected force from Gibraltar. Uneventful. | |
14 | Dotta, Antonio | 21 Jul 1941 | 1458 | Cagliari | 24 Jul 1941 | 0745 | Cagliari | 352 | Patrolled off Cape Bougaroni, on parallel from 37°30'N, 06°00'E to 05°00'E, with Alagi in an adjacent area. All torpedoes expended. | |
22 Jul 1941 | 2307 2310 (e) | 38° 10'N, 5° 30'E | At 1005 hours, as Cape Bougaroni was in sight, information was received that, at 0850 hours, an aircraft had spotted a large naval force in 38°26' N, 03°25' E. At 1130 hours, a signal from MARICOSOM revealed that a force of one battleship, one aircraft carrier and four destroyers had been sighted at 0920 hours in 38°26' N, 03°35' E, steering 090° at 18 knots. T.V. Antonio Dotta estimated that this force could be 45 miles north of his position, at 1630 hours. He immediately altered course, expecting to reach the interception course at 1600 hours. At 1440 hours, as Diaspro was proceeding northward, an order from MARICOSOM gave her freedom of action to move outside her patrol area to intercept the enemy. At 1920 hours, a new signal from MARICOSOM reported the enemy's position at 1545 hours as 75 miles north of Cape Bougaroni, steering 090° at 20 knots. It was now described as one battleship, one aircraft carrier and seven destroyers. However, this position was only 7 miles from Diaspro at 1545 hours and, since no hydrophone noises had been picked up, Dotta estimated that the position provided by MARICOSOM was erroneous. At 1950 hours, bomb explosions could be heard to the west. At 2015 hours, Diaspro was informed by MARICOSOM that an enemy naval force had been reported at 1505 hours, 75 miles north of Cape Sigli, consisting of a battleship, an aircraft carrier, four cruisers and five destroyers. It was not clear if this was the same force or a different one. At 2200 hours, the submarine submerged briefly to listen with the hydrophones and detected numerous noises westward. All forward tubes were readied as Corallo proceeded on the surface. At 2258 hours, shadows were sighted and, two minutes later, the diesels were stopped and the electric motors switched on for a silent approach. At 2304 hours, a naval force of eight to ten ships was sighted in the process of reverting course from 090° to 270°. It could now be identified as one or two destroyers leading the formation, followed by four cruisers, other destroyers, a battleship, an aircraft carrier and one or two destroyers bringing up the rear. The speed was estimated at 10 knots and distances varied from 1,000 to 1,300 metres. At 2307 hours, a full salvo of four torpedoes was fired from the bow tubes aimed at the cruisers. They missed. T.V. Dotta believed that the very visible phosphorescence of the torpedo tracks had enabled the enemy to take avoiding action. At 2309 hours, Diaspro had reverted course to fire two stern torpedoes aimed at the battleship and aircraft carrier from 700 metres and then crash-dived. Two explosions were heard about a minute after firing leading Dotta to believe that he had scored one or perhaps both the major units. This was Force H covering the SUBSTANCE convoy, with the battle cruiser HMS Renown, the battleship HMS Nelson, the light cruiser HMS Hermione, the aircraft carrier HMS Ark Royal and screened by destroyers. One of these destroyers, HMAS Nestor, stationed on the starboard wing, reported two torpedoes, which were avoided. Just prior to this, two explosions had been heard which were probably torpedoes from Diaspro's first salvo, either detonating prematurely or hitting the sea bed. The destroyer now obtained an ASDIC contact at 1,700 yards and dropped a pattern of five depth charges set at medium depth, which exploded as the submarine had reached a depth of 40 metres. Another pattern of six depth charges was dropped on a second run and the same number on a third run. Nothing was seen, but there was a strong smell of oil. In the submarine, about thirty depth charges were heard from 2312 to 0050 hours on 23rd July. Although, the first pattern was close, the remainder were not and the submarine was only slightly damaged. Diaspro had dropped to a depth of 138 metres before stabilising at 116 metres. At 0330 hours, she made an enemy report and at 0557 hours sighted a squadron of destroyers apparently hunting her. Diaspro dived and proceeded to Cagliari. This is one of the rare instances, when an Italian submarine returned from a patrol in the Mediterranean having expended all her torpedoes. | |||||||
15 | Dotta, Antonio | 30 Jul 1941 | 2025 | Cagliari | 6 Aug 1941 | 0650 | Cagliari | 432 | Patrolled off Cape Bougaroni on 6° E meridian. At 1335 hours on 3rd August, Diaspro was informed of a convoy of eight ships in 37°20'N, 10°45'E, on course 270°, 10 knots and moved westward with the intention to carry out a night attack. Sighted only French ships. | |

Dotta, Antonio | 23 Aug 1941 | 1320 | Cagliari | 23 Aug 1941 | 1816 | Cagliari | 27 | Exercises. | ||
16 | Dotta, Antonio | 24 Aug 1941 | 2200 | Cagliari | 27 Aug 1941 | 1410 | Cagliari | 307 | Patrolled west of La Galite within 10 miles from 37°30'N, 07°40'E. | |
25 Aug 1941 | 0910 | 37° 48'N, 8° 00'E | At 0010 hours, a submarine believed to be Aradam, was sighted. As a precaution, Diaspro proceeded submerged to her patrol area, which was 25 miles away at the time and again sighted the submarine at 1013 hours. | |||||||
17 | Dotta, Antonio | 12 Sep 1941 | 1355 | Cagliari | 15 Sep 1941 | 1050 | Cagliari | 359 | Patrolled east of La Galite between 37°32'N and North African coast, 08°56'E and 09°20'E. | |
12 Sep 1941 | 1855 1852 (e) | 38° 42'N, 9° 30'E | At 1855 hours, Diaspro was mistaken for an enemy submarine and attacked by Cant Z.506 no. 3 of 188^ Squadriglia based at Elmas. The aircraft dropped two bombs set to explode at a depth of 15 meters. The submarine was shaken, but escaped by diving to 70 meters. The aircraft observer G.M. Paolo Tavolato was reprimanded. | |||||||
18 | Dotta, Antonio | 16 Sep 1941 | 2355 | Cagliari | 17 Sep 1941 | 2145 | Cagliari | 184 | Sailed for patrol off SE of Minorca to form a patrol line with Serpente but then recalled. Uneventful. | |
17 Sep 1941 | 1240 | At 1240 hours, the submarine Serpente was sighted at a distance 8,000 metres on opposite course. Diaspro had received the recall order but Serpente had not yet. | ||||||||
19 | Dotta, Antonio | 25 Sep 1941 | 1835 | Cagliari | 2 Oct 1941 | 1100 | Cagliari | 814 | Sailed with Axum, Aradam and Serpente for patrol between 39°10'N and 39°50'N, and between 06°40'E and 07°00'E on a patrol line with them. On 27th September, was moved 100 miles south (in 38°25'N then moved to 37°30'N, 07°00'E on 28th September) then off Cape Bougaroni. | |
29 Sep 1941 | 0617 0612 (e) | 37° 32'N, 6° 45'E | At 0617 hours, in dense rain showers, a destroyer was suddenly sighted at a distance of 250 metres. Almost at the same another large shadow appeared at 2,500-3,000 metres. Diaspro fired her two stern tubes and crash-dived. After 3 minutes a loud explosion was heard as the submarine was at a depth of 30 metres. This was the destroyer HMS Gurkha, on the port side of the screen of HMS Ark Royal, HMS Prince of Wales and HMS Rodney, covering the HALBERD convoy. The destroyer sighted the torpedo wakes and managed to avoid them. At 0622 hours, she heard two explosions, which were probably the torpedoes reaching the end of their run. The Dutch destroyer HrMs Isaac Sweers joined the hunt, but did not drop any depth-charges. HMS Gurkha got a contact at 0810 hours, in 37°26' N, 07°14' E and ,dropped fourteen depth-charges. With the fleet proceeding at 17 knots on an easterly course, it could not have been the same submarine. | |||||||
1 Oct 1941 | 0814 | (0) Near La Galite. | At 0814 hours, a submarine believed to be Aradam was sighted. | |||||||
2 Oct 1941 | 0700 | (0) Near Cagliari. | At 0700 hours, the submarine Serpente was sighted. | |||||||
20 | Dotta, Antonio | 16 Oct 1941 | 2355 | Cagliari | 21 Oct 1941 | 1225 | Cagliari | 540 | Sailed with Aradam, Serpente, Turchese and Alagi for patrol north of Cape de Fer between 37°30'N and 37°40'N, and between 06°40'E and 07°20'E on a patrol line with them (the four submarines were spread from 37°10'N to 37°50'N, each occupying a zone 10 miles deep). | |
17 Oct 1941 | 0715-1010 | 38° 27'N, 8° 28'E | At 0700 hours, the submarine Serpente was sighted at 8,000 metres and remained in sight until 1010 hours. | |||||||
20 Oct 1941 | 1900 1650 (e) | 38° 05'N, 8° 00'E | At 1900 hours, three vessels were sighted at over 10,000 metres. They were recognised as destroyers, two of the FEARLESS class and one of the JERVIS class. These were probably the light cruisers HMS Aurora and HMS Penelope and the destroyers HMS Lance and HMS Lively (Force K) proceeding to Malta. Diaspro could not close to carry out an attack. | |||||||
21 | Dotta, Antonio | 24 Oct 1941 | 2305 | Cagliari | 3 Nov 1941 | 1415 | Cagliari | 972 | Sailed for patrol with Alagi, between 37°15'N and 37°30'N and, and between 05°20'E and 06°00'E. Uneventful. Heard only H.E. | |

22 | Dotta, Antonio | 7 Nov 1942 | 0145 | Trapani | 14 Nov 1942 | 1830 | Trapani | 1820,5 | Patrolled in 37°25'N, 10°15'E to attack an enemy convoy. On 8 November, moved to area between 37°00'N and 37°20'N, and between 06°00'E and 06°20'E. | |
8 Nov 1942 | 1158 | 35° 25'N, 10° 15'E | At 1158 hours, Diaspro collided with the submarine Alagi as they were proceeding submerge to their patrol areas. Diaspro was at a depth of 12 metres at the time and suffered only minor damages but Alagi had to return to base for repairs. | |||||||
12 Nov 1942 | 0505 | 36° 46'N, 5° 06'E | At 0456 hours, a large vessel was sighted at a distance of 1,200 metres. She was estimated doing 14 knots. At 0505 hours, Diaspro fired all four bow tubes (533mm, G7e type) at a range of 800 metres, adjusted for an enemy's speed of 10 knots as the initial speed appeared to have been overestimated. However, the torpedoes had just left the tubes when the vessel altered course to port and they missed. This was probably the Dutch liner Marnix Van St. Aldegonde (19,355 GRT, built 1930) who anchored off Cape Bouak at 0800 hours coming from Cape Aokas [36°38'45" N, 05°13'54" E] where she had taken refuge the previous day. At 0510 hours, the submarine had reverted and fired a single stern torpedo from a range of 1,500 metres. At 0513 hours, a double explosion was heard. No vessels reported being torpedoed at this time. | |||||||

21 Dec 1942 | 0055 | 38° 05'N, 8° 30'E | At 0055 hours, a vessel initially believed to be a submarine was sighted but may have been an A/S vessel. Diaspro submerged and heard explosions coming from the direction of the vessel. | |||||||
22 Dec 1942 | 2240-2245 | 38° 12'N, 8° 29'E | At 2245 hours, a submarine was sighted on a northerly course. This was perhaps HMS P 247 (later named HMS Saracen). Diaspro lost contact in a rain squall. | |||||||
23 Dec 1942 | 0255 | 38° 12'N, 8° 27'E | At 0255 hours, a submarine was sighted on a northerly course at a distance of 3,000 metres. This was perhaps HMS P 247 again. Diaspro lost contact. | |||||||

12 May 1943 | 2251 | 38° 56'N, 5° 22'E | At 2251 hours, an aircraft was seen at 1,000 metres and the submarine dived. When it reached a depth of 50 meters, a leak was noticed, through the stern torpedo tube no. 6. Diaspro surfaced and at 0545 hours on the 13th, a rating donned a diving apparatus and managed to remove an obstruction from the tube door stopping the leak. | |||||||
17 May 1943 | 0630 | (0) 058° - Porto Torres - 4.7 miles. | At 0630 hours, Diaspro came under fire from an Italian coastal battery when she was mistaken for an enemy submarine. Fortunately, the nearest round fell some 800 meters short and, after making recognition signals and displaying the Italian flag, the battery checked fire. | |||||||

11 Jul 1943 | 2141 | (0) Near Sardinia. | At 2141 hours, a submarine was sighted on a southerly course at a distance of 5,000 metres. Shortly after, another submarine was sighted at a distance of 3,000 metres steering WNW. Diaspro took avoiding action. | |||||||
13 Jul 1943 | 0113 | 37° 05'N, 7° 40'E | At 0000 hours, two shadows were sighted. The submarine closed to 5,000 metres and identified them as two 10,000-ton steamers. Shortly after, a destroyer was sighted in between them. At 0007 hours, the destroyer, closing on Diaspro, was now at 1,000 metres and T.V. Donato decided to dive to 60 metres. At 0102 hours, the submarine surfaced and immediately sighted a large steamer escorted by two corvettes at a distance of 3,000 metres. At 0113 hours, four torpedoes were fired from the bow tubes, at a distance of 2,500 metres, at the steamer estimated to be of 15,000 tons. Her speed was intially estimated to 15 knots, but later corrected to 8 knots. It was then realised that the vessel was perhaps going at a slower speed causing the torpedoes to miss. Diaspro now reverted course. At 0120 hours, the two stern torpedoes were fired at a range of 2,500 metres. Two hits were heard after 148 seconds but no such success is confirmed in British documents. The target has not yet been identified. | |||||||
27 | Donato, Alberto | 23 Jul 1943 | 2205 | Naples | 3 Aug 1943 | 0738 | Naples | 887,7 | Patrolled off Pantelleria and east coast of Sicily for operation ZETA. | |

25 Jul 1943 | 0310 | (0) Near Point M3 (near Cape Vaticano). | At 0310 hours, two Italian steamers and a corvette were encountered on an opposite course. This was the convoy consisting of Viminale, Magliulo and Petsamo escorted by the torpedo boat Pallade, the corvette Gabbiano and the tug Forte and Tenax sailing from Messina for Naples. Pallade fired four star shells before recognising the submarine. | |||||||
26 Jul 1943 | 0220 | 37° 38'N, 16° 38'E | At 0220 hours, an aircraft was seen and the submarine dived. | |||||||

27 Jul 1943 | 0243 | At 0243 hours, a MTB was sighted and Diaspro dived. | ||||||||
27 Jul 1943 | 0405 | 36° 30'N, 16° 09'E | At 0405 hours, an aircraft was seen and the submarine dived. | |||||||
27 Jul 1943 | 0440 | At 0440 hours, several aircraft were seen and the submarine dived. | ||||||||
27 Jul 1943 | 2308 | 36° 20'N, 15° 02'E | At 2308 hours, flares apparently dropped by an aircraft were seen and the submarine dived. | |||||||
28 Jul 1943 | 0232 | At 0232 hours, a MTB was seen and the submarine dived. | ||||||||
28 Jul 1943 | 1713 | 36° 22'N, 14° 40'E | At 1713 hours, an aircraft was seen when Diaspro was at periscope depth. She went deep. | |||||||
28 Jul 1943 | 2345 | At 2345 hours, a MTB was seen and the submarine dived. | ||||||||
29 Jul 1943 | 0120 | At 0120 hours, a MTB was seen and the submarine dived to 50 metres. | ||||||||
29 Jul 1943 | 2210 | At 2210 hours, a hospital ship was sighted and the submarine crash-dived, perhaps to avoid a collision. | ||||||||
2 Aug 1943 | 2215 | 39° 07'N, 11° 56'E | At 2215 hours, flares, apparently dropped by an aircraft, were seen and the submarine dived. | |||||||

18 Aug 1943 | 0052 | 38° 41'N, 15° 20'E | At 0048 hours, two enemy destroyers were sighted, steering 149° at a distance of 8,000 metres. At 0052 hours, Diaspro fired two stern torpedoes (533mm, S.I. type) at a distance of 5,000 metres. They missed. | |||||||
19 Aug 1943 | 2323 | 38° 42'N, 15° 20'E | At 2319 hours, two destroyers were sighted steering 099°. Diaspro fired four torpedoes (533mm, G7e type) from her bow tubes at a range of 3,500 metres. Two were claimed to have hit. T.V. Donato believed he had sunk one and damaged the other. At 0145 hours, an immobilised destroyer was sighted but the submarine had expended all her torpedoes and could not finish her off. Unfortunately, the results were not confirmed. This was the last attack by an Italian submarine in the Mediterranean Theatre. | |||||||
