At 06:18 on 13 May, the 4,471-ton Swedish merchant ship "Tolken" was hit by a single torpedo from "U-94". The U-boat was driven off by the convoy escorts, but returned at 09:30. Approaching the damaged ship on the surface, the U-boat was shot by the ship's machine guns. At 10:20 the U-boat attacked again with torpedoes. The first failed to explode, but the second five minutes later hit and sank the ship. There were no losses amongst the ship's crew of 34, and all were picked up by the British rescue ship "Bury".
