German submarine U-841

German submarine U-841 was a Type IXC/40 U-boat built for Nazi Germany's Kriegsmarine during World War II.

U-801 was ordered in January 1941 from DeSchiMAG AG Weser in Bremen under the yard number 1047. Her keel was laid down on 21 March 1942 and after seven months of construction the U-boat was launched on 21 October 1942. On 6 February 1943 she was commissioned into service under the command of Kapitänleutnant Werner Bender (Crew 36) in the 4th U-boat Flotilla.

Transferred to 2nd U-boat Flotilla, U-841 left Kiel for Bergen on 26 August 1943 arriving there six days later. On 9 September 1943 she left Bergen for operations in the North Atlantic. Stopping over in Trondheim, she joined wolf pack Schlieffen operating against convoy ONS-20 in October 1943. In the afternoon of 17 October 1943, U-841 was spotted and attacked by an aircraft from 120 Squadron, RAF. One of ONS20's escorts, HMS Byard, picked up U-841 on its ASDIC later that day and depth-charged it. Heavily damaged, the U-boat surfaced and was scuttled by its crew. While the crew abandoned ship, Byard opened fire on the U-boat. 27 crew members, including the captain, died, while 27 survivors were picked up.
