Loss position

View the 1 war patrol

U-865 left Trondheim on 8 September 1944 for a patrol in Canadian waters, but no signals were received from this boat after sailing and it was posted as missing on 1 October 1944. It is possible that U-865 was lost in an accident because three previous attempts to reach the North Atlantic had been made that all failed owing to problems with the Schnorchel.

Previously recorded fate

  • Probably sunk 19 Sept, 1944 north-west of Bergen, in position 62.20N, 02.30E, by depth charges from a British Liberator aircraft (Sqdn. 206/S).
    Notes. This attack was actually against the U-858 inflicting minor damages.

Attacks on this boat and other events

27 Jul 1944
Outbound, one day from Trondheim: the boat was attacked by a British Liberator (86 Sqn RAF/R, pilot G.G. Gates) with six depth charges, sustaining moderate damage. The Germans put up a powerful flak barrage, hitting engines #1 and #2 and setting it on fire. Both subsequently managed to return to base. (Sources: Blair, vol 2, page 598)

1 recorded attack on this boat.

Schnorchel-fitted U-boat
This boat was fitted with a Schnorchel underwater-breathing apparatus in July 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-865 did not suffer any casualties (we know of) until the time of her loss.
