At 03.29 hours on 22 June 1941 the unarmed Calabria (Master John Godfrid Olsson), a straggler from station #115 in convoy SL-76 due to a foul bottom since 4 June, was hit on the starboard side aft of amidships by one torpedo from U-141 and sank by the stern after 30 minutes about 100 miles 280° from Inishtrahull Lightship. The ship had been missed with the first two torpedoes at 00.27 and 02.13 hours. Three crew members on watch below were killed by the explosion. All survivors, four of them injured, abandoned ship in the port lifeboat about ten minutes after the hit because the starboard boat had been damaged. While the lifeboat sailed for the nearby coast, they observed an outbound convoy and twice spotted an aircraft without being able to attract attention until a third aircraft finally saw them about three miles off land and alerted the destroyers HMS Cossack (F 03) (Capt P.L. Vian, DSO, RN) and HMS Sikh (F 82) (Cdr G.H. Stokes, RN), which were on an anti-submarine patrol in the area and had inspected the Swedish ship a few days before the attack. At 23.00 hours on 23 June, the survivors were picked up by the latter about 1,5 miles from Inishtrahull, transferred to HMS Guardian (T 89) (A/Capt H.A.C. Lane, RN) at Moville and eventually landed at Londonderry.
