Loss position

View the 1 war patrol

U-683 sent its last radio message on 20 February 1945 from approx. position 55.00N, 12.30W while en route to its operational area off Cherbourg. The boat was posted as missing on 3 April 1945 after it failed to return to Stavanger. It is possible that U-683 was mined on or after 28 February 1945 in the British minefield HW A1 in position 50.31,4N, 05.22,8W.

Previously recorded fate

  • Missing since 12 March, 1945. Probably sunk 12 March, 1945 in the English Channel near Land's End, in position 49.52N, 05.52W, by depth charges from the British frigate HMS Loch Ruthven and the British sloop HMS Wild Goose. (Postwar assessment)
    Notes. This attack was probably against the wreck of U-247.

Schnorchel-fitted U-boat

This boat was fitted with a Schnorchel underwater-breathing apparatus and sailed equipped with it in February 1945 but it was of course installed prior to that date.

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-683 did not suffer any casualties (we know of) until the time of her loss.
