Missing since 9 September 1944 in the Norwegian Sea. There is no explanation for its loss. 59 dead (all hands lost).
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.
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.
