  28 Mar 1941
1210 (e)
At 1210 hours, a British bomber reported an enemy submarine. This may have been Dagabur, who reported close and distant explosions during the day.
  28 Mar 19410804
(0) West of Malta.
At 0804 hours, Dagabur heard H.E. followed by explosions in the vicinity and believed she was the subject of a systematic A/S hunt. The submarine escaped without damage.
  30 Mar 1941203733° 47'N, 25° 24'EAt 2100 hours on 29th March, two signals were received, one reporting a convoy and the other a naval force located about 30 miles away. Dagabur altered course to intercept.

At 1835 hours on 30th March, a cruiser of the LIVERPOOL class was sighted at a distance of 7,000 metres. The submarine disengaged.

At 2027 hours, another cruiser of the LIVERPOOL class was sighted at distance of 8,000 metres.

At 2037 hours, the range had closed to 3,000 metres and two torpedoes were fired, aimed at the cruiser. Two hits were heard after 170 seconds.

It is possible that this was the light cruiser HMS Bonaventure who was sunk by Ambra at 0244 hours on the 31st. Some sources have mentioned that Dagabur damaged Bonaventure before she was finished by Ambra. There is no evidence to support this theory. If Bonaventure was Dagabur's target, there is little doubt that she was missed.

At 0515 hours, hydrophone effects were heard, followed by explosions in the vicinity. Dagabur escaped without damage.
  3 Apr 19411430-2000
(0) West of Malta.
Between 1430 and 2000 hours, H.E. were heard followed by depth-charges at 15 minutes interval in the vicinity of Dagabur who was later believed to be the target of a systematic A/S hunt. The submarine escaped without damage.

35° 52'N, 15° 32'EAt 0140 hours, an enemy submarine was sighted at a distance of 700 metres, steering 290° at 7 knots. Dagabur disengaged "according to the instructions received". This was HMS Osiris (Lieutenant Commander T.T. Euman, RN) on a storing trip to Malta. The British submarine also sighted the Italian submarine and dived immediately.

  6 Sep 1941092033° 50'N, 24° 18'EAt 0920 hours, a three-engined bomber (Italian?) was sighted. It dived and dropped a bomb on Dagabur. The bomb fell 30 metres on the starboard side. After 20 minutes, the aircraft left.
  7 Sep 19411328
1332 (e)
32° 47'N, 28° 59'EAt 1328 hours, an enemy submarine was sighted surfacing at a distance of 800 metres. This was HMS Torbay (Lieutenant Commander A.C.C. Miers, DSO, RN) who tried to open fire on the Dagabur from a distance of 1,500 yards, but the first round misfired and by the time the shell was removed, the Italian submarine had dived. When Dagabur returned to periscope depth the enemy submarine could not be seen or heard.

A search for this submarine was started on the 8th. The destroyers HMS Hero (Cdr. H.W. Biggs, DSO and Bar, RN), HMS Havock (Lt. G.R.G. Watkins, DSC, RN), HMS Hotspur (Lt. T.D. Herrick, DSC, RN) and HMS Kingston (Lt.Cdr. P. Somerville, DSO, DSC, RN) were sent from Alexandria. HMAS Vendetta (Lt.Cdr. C.J. Stephenson, RAN) was sent from Port Said. HMS Griffin (Cdr. J. Lee-Barber, DSO, RN) and HMS Hasty (Lt.Cdr. L.R.K. Tyrwhitt, DSC, RN) were sent from Haifa.

The hunt was abandoned on the 10th. HMS Hasty, HMS Havock, HMS Hotspur, HMS Kingston proceeded to Alexandria, HMAS Vendetta proceeded to Port Said and HMS Griffin and HMS Hero proceeded to Haifa.

  9 Sep 1941013531° 59'N, 30° 11'EAt 0135 hours, two warships of about 600 tons were sighted at a distance of 3,000 metres. Dagabur moved away.
  9 Sep 1941164032° 11'N, 31° 21'EAt 1640 hours, a destroyer of the SKATE class was sighted proceeding at 8-10 knots. Dagabur dived to 80 metres but was not attacked.

10Torri, Alberto10 Oct 19410730Leros26 Oct 19410625Leros1700,5Patrolled off Alexandretta between 36°00'N and 36°20'N, and between 34°20'E and Syrian coast (also reported as from 34°16'N, 33°00'E to 34°40'N, 34°40'E). ULTRA revealed the patrol without identifying the submarine.
  16 Oct 1941115536° 08'N, 35° 22'EAt 1155 hours, a fishing vessel was sighted at a distance of 6,500 metres. It was not attacked.

11Torri, Alberto21 Nov 19410750Leros6 Dec 19410945Leros1711,1Patrolled off Derna, between 22°00' and 23°00'E, and within 20 miles from the Libyan coast, with Zaffiro in the adjacent area to the west. At 1910 hours on the 25th, MARICOSOM ordered her to switch to the area between 33°00'N and 33°40'N, and between 22°20'E and 23°00'E. The order was again modified at 1810 hours on the 27th, to patrol between 33°20'N and 34°00'N, and between 23°40'N and 24°20'E which was reconfirmed at 1225 hours on the 29th.
  25 Nov 1941194533° 00'N, 24° 00'EAt 1945 hours, signal from MARICOSOM (1740/25) was received mentioning a convoy of five steamers, escorted by two cruisers and four destroyers, sighted at 1155 hours, in 32°50' N, 25°30' E, steering 285° at 14 knots. Dagabur altered course to 360° at full speed to intercept.

At 2215 hours, the submarine was within a few miles of the interception point, when H.E. were heard, but they grew faint and at 2320 hours the chase was abandoned. Dagabur returned to her patrol area.
  28 Nov 1941192233° 50'N, 24° 20'EAt 1922 hours, a vessel was sighted at the limit of visibility, steering 075°, 18 knots. Dagabur gave chase but lost contact after an hour.

12Torri, Alberto10 Dec 19410150Leros20 Dec 19411207Leros1335Patrolled between Gaudo and Alexandria within 20 miles from 34°00'N, 25°45'E (Grids 3664 and 6664).
  14 Dec 19411955
1956.5 (e)
34° 01'N, 26° 02'EAt 1950 hours, the starboard lookout reported a vessel that could not be identified. The submarine immediately steered towards it. At a distance of 3,000 metres it was thought to be a cruiser as Dagabur was moving to the attack at 12.4 knots.

At 1955 hours, a single torpedo was fired from a bow tube (type not specified, but probably 450mm) at a range of 2,100 metres and 20 seconds later a second torpedo (533mm) was fired. Dagabur immediately submerged. Two explosions were heard after 105 seconds.

The "cruiser" was actually the submarine HMS Talisman (Lieutenant Commander M. Willmott, RN). She had also sighted the Italian submarine (mistaken for German) at a range of 800 yards and had time to fire two 4" rounds from a distance of 100 yards before her opponent submerged. The first round missed, but the second was claimed to have hit the conning tower about 3 feet above the casing. It was believed that the enemy submarine may have dived with her hatches open and sank.

Dagabur was indeed hit by a 4" round, but it only caused minor damages to the wireless antenna and it was quickly repaired.

Some sources have claimed that the light cruiser HMS Galatea was damaged in this attack. HMS Galatea was sunk four hours later some 250 miles away.

13Torri, Alberto11 Feb 19421755Leros23 Feb 19421155Leros1398,5Patrolled between 31°40'N and 32°50'N, and between 33°00'E and 34°00'E, off Port Said and the Palestinian coast. On 13 February, No. 3 torpedo tube was accidentally flooded and the submarine continued on her patrol with only three effective forward tubes. Uneventful.

At 0100B hours, the destroyer HMS Wolverine was escorting the aircraft carrier HMS Furious with the destroyers HMS Keppel and HMS Malcolm, when she detected a submarine by radar. She raced at 26 knots and rammed the submarine. The damage forced the destroyer to return to Gibraltar.

There is little doubt that her victim was Dagabur. There were no survivors, T.V. Renato Pecori, four officers and forty ratings perished.
