At 16.42 hours on 10 Sep 1941, U-85 fired a spread of two torpedoes at a ship in convoy SC-42 northeast of Cape Farewell and reported one ship sunk and another probably damaged after observing one hit and hearing a second detonation. However, only Thistleglen (Master Gordon Frederick Dodson), the ship of the vice-commodore, was hit by one torpedo and sank later. Three crew members were lost. The master, 39 crew members and six gunners abandoned ship in three lifeboats and two rafts and were picked up after about one hour by the Lorient, a straggler from the same convoy and landed at Belfast.
