German submarine U-233 was a Type XB U-boat of Nazi Germany's Kriegsmarine during World War II. She was laid down on 15 August 1941, launched on 8 May 1943 and commissioned on 22 September of the same year. U-233 was commanded throughout her career by Oberleutnant zur See Hans Steen.

Service history

U-233 was assigned to the 4th U-boat Flotilla for training on 22 September 1943 and to the 12th U-boat Flotilla on 1 June 1944 for active service. Her first and only patrol commenced on 27 May 1944 when she departed Kiel to lay mines off Halifax.

Fate

On 5 July 1944 U-233 was intercepted by ships of the USS Card (CVE-11) hunter-killer group. She was identified by sonar, depth-charged to the surface and fired on by USS Baker (DE-190), before being rammed and sunk by USS Thomas (DE-102). 32 of her crew were killed in the action, 29 others being rescued by the escorts. Steen was also picked up, but died of wounds the next day. [4] [5] [6] US Navy report on U-233 survivors 1944[7]
