Attacks on this boat and other events
10 Apr 1944
03.04 hrs, Bay of Biscay, inbound: Leigh Light equipped Mk.V Liberator BZ781 (RAF Sqdn 53/A, pilot F/O W. J. Irving, RCAF) attacked following a radar trace. The depth charges failed to release on the first run, and also on the next two passes, possibly due to flak hits in the bomb bay on the second approach. The undamaged U-821 escaped further strafing attacks by diving after 20 minutes. The Liberator was left with an inoperable tail gun turret and damaged hydraulics and nose wheel. The damage was noticed, and F/O Irving managed to reach base and then land without flaps or brakes at first light - for which he later received the DFC. (Sources: Franks/Zimmerman)
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-821 did not suffer any casualties (we know of) until the time of her loss.
