30 May 1943
While en-route from Algiers to her patrol area in the Gulf of Lyon HMS Trespasser (Lt. R.M. Favell, RN) fires three torpedoes (in error) at a dead whale. Position was about 30 nautical miles South of Mallorca, Spain.

(All times are zone -2)
0438 hours - Sighted a dark shape on the port bow. The Officer of the Watch went to Night Alarm Stations. The dark shape turned out to be a large dead whale floating on the surface. As Trespasser passed it the first time it was thought to be a boat so Trespasser turned around to have another look. Lt. Favell was about to give the order 'Fall out Night Alarm Stations' when he realized that the torpedo tubes had not been reported as ready. He therefore gave the order 'Report when the tubes are ready'. He then turned his glasses once more at the whale. About 15 seconds later he saw the tracks of two torpedoes leave their tubes (three were fired). The order given was not understood correctly by the TGM (Torpedo Gunner's Mate) and thought to be 'Fire the Port tubes when ready'. The torpedo officer, who could otherwise has stopped this from happening was not in the forward torpedo room as he was at that moment the Officer of the Watch.

8 Jun 1943
HMS Trespasser (Lt. R.M. Favell, RN) fires 6 torpedoes at a tanker off Marseilles, France. No hits were obtained.

(All times are zone -2)
0910 hours - In position 160° Cassidaigne Reef, 3.5 nautical miles sighted a large A/S trawler off Riou Island (near Marseilles, France). It appeared to be patrolling up and down. As this was the last day of the patrol Lt. Favell decided to take a shot at it.

1000 hours - Sighted three tankers and another trawler coming out of the mist. Shifted target to this convoy. Decided to attack the stern most tanker. About six smaller A/S vessels were also observed to be around this convoy.

1014 hours - Fired 6 torpedoes at the third tanker (thought to be about 4000 tons) and then went deep. Range was 6000 yards.

1018 hours - Heard one explosion that sounded like a torpedo hitting the target, giving it a running range of nearly 5850 yards.

1021 hours - Heard five more explosions as the rest of the torpedoes hit the shore. An ineffective counter attack followed by the two A/S trawlers and a couple of smaller A/S vessels. No depth charges were dropped.

1600 hours - After reloading the torpedo tubes returned to periscope depth to find nothing in sight.

Looking at German sources the convoy must have been the following; three tanker barges Savoie, Norte and Citerna XI. They were escorted by UJ 2214, R 1, R 6, R 7 and R 8. They had sailed from Marseille at 0700 hours and arrived at Toulon at 1355 hours. They did not observe the attack (which was a long range attack, carried out from 6000 yards) but the description of the convoy fairly matches the one given by Trespasser: three tankers escorted by an A/S trawler and several E-boats and if one looks at a map they should have been in the vicinity of Trespasser at that time.
