Loss position

See the 3 ships hit by U-857 - View the 3 war patrols

There is a chance that this boat was sunk by the escort vessels currently being credited for U-879 as both boats might have been in the area at the same time.

Another chance is that she was sunk by an American Blimp (airship) that made a claim of dropping a homing torpedo on a submarine on 18 April, 1945.

Previously recorded fate

  • Sunk 7 April, 1945 in the North Atlantic east of Boston, USA, in position 42.22N, 69.46W, by depth charges from the US destroyer escort USS Gustafson. (Postwar assessment)
    Notes. This attack was actually against a nonsub target.

Schnorchel-fitted U-boat
This boat was fitted with a Schnorchel underwater-breathing apparatus in September 1944. Read more about the Schnorchel and see list of fitted boats.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-857 did not suffer any casualties (we know of) until the time of her loss.
