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.
Notes. This attack was probably against the wreck of U-247.
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.
