Missing since 11 September 1944 in the area southeast of Iceland. 56 dead (all hands lost). (FDS/NHB, September 1987).
The boat was returning from a weather reporting patrol when she possibly hit a mine on or about the 17 September in the Iceland-Faroes mine barrage.
Previously recorded fate
- Sunk by a British Liberator (RAF 224/A) on 24 Sept 1944 in position 61.00N, 04.07E. (Postwar assessment)
Notes. This attack was instead against the U-763 inflicting medium damage.
This boat was fitted with a Schnorchel underwater-breathing apparatus and sailed equipped with it in July 1944 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-855 did not suffer any casualties (we know of) until the time of her loss.
