Service history

She undertook three patrols, the first was for training. She sank two ships for a total tonnage of Шаблон:GRT, and damaged one other ship on her last two patrols.[1] She sank Шаблон:MV on 14 April 1945, Шаблон:SS on 18 April 1945 and damaged Шаблон:MV on 23 April 1945.

Fate

U-857 went missing since 30 April 1945 in the North Atlantic Ocean off the east coast of the United States. All hands were lost, and no wreckage was found.

The U-boat had been claimed to have been sunk by depth charge hedgehogs off the coast of Massachusetts on 7 April 1945 by Шаблон:USS and was also thought to have been possibly sunk by Шаблон:USS.[2] However more recent commentary surmised that Gustafson had not hit her, and her loss is currently unexplained.[3][4] U-857 was considered as a possible identity for the wreck that was ultimately determined to be U-869.[5]
