German submarine U-744 was a type VIIC U-boat, launched on 11 March 1943, commanded by Heinz Blischke.[1]
Service History
She had two patrols, one from 5 June 1943 to 30 November 1943 and 1 December 1943 to 6 March 1944. She sank two ships in total, SS Empire Housman on 3 January 1944, and the landing ship tank LST 362 on 2 March 1944. The LST 324 was also damaged that day.[2]
U-744 was forced to surface on 6 March 1944, after a 31 hour pursuit by British and Canadian ships. She was depth-charged by HMS Icarus, causing her crew to abandon her. They were picked up by the corvette HMS Kenilworth Castle, the Canadian frigate HMCS St. Catharines, corvettes HMCS Fennel and HMCS Chilliwack and destroyers HMCS Chaudiere and HMCS Gatineau in the North Atlantic. U-744 was then boarded by allied sailors, who retrieved code books and other documents. Most of this was lost while being transferred between the U-Boat and the allied ships. After attempts to tow the submarine into port failed, U-744 was scuttled by the allied warships.[3]
