Loss position

View the 1 war patrol

The boat struck a rock while submerged near the Bishop Rock and was forced to surface and was then attacked by the Liberator aircraft. It sank roughly 4 miles to the north-east of the Isles of Scilly.

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-681 did not suffer any casualties (we know of) until the time of her loss.
