German submarine U-861 was a long-range Type IXD2 U-boat built for Nazi Germany's Kriegsmarine during World War II. Laid down in Bremen and launched on 29 April 1943. She was equipped with two stern torpedo tubes and 24 mines.

She was commanded throughout her service life by Kapitänleutnant Jürgen Oesten (Knight’s Cross).

Service History[edit]

She joined 4th Flotilla for training on 2 September 1943, where she remained until 31 March 1944. She then joined 12th Flotilla for active service until 30 September 1944. For her last assignment, she joined 33rd Flotilla, as part of Monsoon Group operating out of Penang in the Indian Ocean, on 1 October 1944 until the end of the war. On her final long trip back to Norway carrying vital supplies from the Far East, she struck an iceberg south of Greenland, but reached Trondheim safely on 19 April 1945, with very little fuel remaining.

Fate[edit]

U-861 surrendered on 9 May 1945 at Trondheim, Norway. She was transferred to Lisahally, Northern Ireland shortly afterwards.
She was sunk by the Royal Navy on 31 December 1945 in position 55°25′N 07°15′W / 55.417°N 7.250°W / 55.417; -7.250 as part of Operation Deadlight.
