Service history.
After work up for deployment in the Baltic Sea, "U-806" transferred to the 33rd U-boat Flotilla for front-line service on 1 November 1944. She left Kiel for her first - and only - war patrol on 30 October. On the way to her assigned operational area off Canada she stopped at Horten Naval Base and Kristiansand. While operating against convoy HX 327 in late December 1944, "U-806" sank two ships, the British steamer of  GRT, and the Canadian escort HMCS "Clayoquot" on 21 and 24 December respectively. An attack on another Canadian escort, HMCS "Transcona", failed.
Two months later, "U-806" returned to base via Norway, arriving in Flensburg on 27 February 1945. Spending the rest of the war in training, "U-806" ran aground on Hatter Reef on 5 May 1945 and had to be towed free by a tug the next day. She arrived in Aarhus later that day in order to surrender to the Allies.
On 22 June 1945 the U-boat was transferred to Loch Ryan via Fredericia, Kiel, and Wilhelmshaven, arriving in Scotland on 26 June. On 21 December 1945, as part of Operation Deadlight, "U-806" left Loch Ryan under tow from to be sunk by by artillery.
