April 1942 - Patrolled off Lampedusa.

23rd September 1942 - Departed Malta to patrol west coast of Greece.
27th September 1942 - Attacked a heavily escorted convoy firing a full salvo of four torpedoes at the very long range of 9000 yards on a rather late track. Hit and damaged Francesco Bartaro. At sunset she was able to surface and follow up getting into a position for another very long-range attack in which she fired two torpedoes. She was further counter attacked but her target was hit and after floating for some hours, finally sank. Having expended all of her torpedoes she returned to Malta.

10th October 1942 - Fired three torpedoes at a large Italian destroyer. Unfortunately she underestimated her speed and missed astern.

Fired a single torpedo at the salvage tug Pronto hitting and sinking her. Fired two torpedoes at the beached ship and both hit. The target was Amsterdam and she settled on the bottom in shallow water. Attempts to salvage her continued for several months but failed.

3rd December 1942 - Sighted a northbound ship north of Mahedia on the east coast of Tunisia. Attacked with gunfire at close range and stopped her. Her destruction was completed, as soon as it had been made certain that there were no prisoners of war on board, by gunfire. This was the Sacro Cuore.  Returned to Malta to land Luftwaffe prisoners who had been found on board.

13th December 1942 - Fired two torpedoes at a small ship north of Sousse escorted by aircraft but missed. She had another chance an hour later and this time hit Macedonia with a single torpedo. With a deck cargo of motor transport she sank in shallow water. An hour or so later tried to finish her off while she had a torpedo boat alongside. The single torpedo, however ran wide of the mark.

6th January 1943 - Departed Malta to patrol in the Kerkenah-Hammamet area.
9th January 1943 - Sighted a small northbound ship escorted by four F-boats.  Fired a single torpedo and missed due to a drill failure.  Later a second torpedo was fired from nearly right astern and also missed. The target was a slow one and she was able to pursue submerged until it was dark when she surfaced and overtook the enemy reaching a surface firing position. Another single torpedo was fired which hit and sank Emilio Morandi.
10th January 1943 - Fired a single torpedo at a small tanker and missed. She then surfaced and engaged with her gun but before she could obtain a hit the enemy escaped into Monastir.
