At 03:02 hrs Empire Amethyst received a distress call from the American SS Delvalla which had been torpedoed by U-154 and was sinking. Prince Henry headed for the reported position of the Delvalla and a Catalina aircraft was despatched. The survivors were taken aboard Prince Henry.
U-154 spotted Empire Amethyst again at 11:42 hrs; she was again under escort by Prince Henry but at 16:00 hrs the escort had been lost. As he was short of torpedoes, Kapitän Kölle decided to attack from the surface. The chase began at 20:00 hrs with Empire Amethyst zig-zagging but generally following a heading of 110° towards Trinidad. Empire Amethyst managed to lose her pursuer at 00:24 on 13 April by making a sharp turn. At 01:27 hrs, Kölle ordered his engines stopped to try to ascertain where Empire Amethyst was. Kölle decided to head in the direction that Empire Amethyst was generally heading and by 04:30 had found her again. At 05:52, Kölle aimed the first of two torpedoes at Empire Amethyst, which hit under the bridge. The second exploded forward of the engine room and she exploded in a mass of flames that were visible from 30 nautical miles (56 km) away. Empire Amethyst sank with the loss of all 47 crew at .
