- On the afternoon of February 29, 1916, both the British armed merchant ship Alcantara and the German raider Grief sink after engaging each other in a close-range battle on the North Sea. The battle raged for 12 agonizing minutes at close range. The Alcantara lost 74 men in the battle; the Grief lost nearly 200. By the time a second British armed merchant ship, the Andes, arrived on the scene, both ships had been badly damaged. On fire and sinking quickly, the desperate Grief fired one final torpedo, striking the Alcantara. Both ships eventually sank. The crew of the Andes picked up the survivors of both ships, taking more than 120 German prisoners.
