The only U-boat in World War II whose crew is known to have killed shipwrecked Allied survivors.

Type: IX D2
Built: A.G. Weser, Bremen
Keel laid: 15 April 1942
Launched: 28 January 1943
Commissioned: 15 June 1943
Commander: KL Heinz-Wilhelm Eck
Fate: On her only patrol, U-852 sank the Greek steamer Peleus, 13 March 1944, and her crew attempted to kill the survivors to conceal her presence. After she proceeded into the Indian Ocean, British aircraft fatally damaged her off the Somali coast on 2-3 May 1944, and she beached herself near Ras Mabber, Somaliland. British forces captured her crew, and in October 1945, a British court in Hamburg subsequently tried, condemned, and executed the captain and two of his officers for war crimes. The court also convicted two other crewmen and sentenced them to prison terms.
