Attacks on U-821 during this patrol
10 Apr 1944
0304hrs, Bay of Biscay, inbound: Liberator Mk.V BZ781 (53 Sqn RAF/A, pilot F/O W.J. Irving, RCAF) made a Leigh Light attack after following a radar trace. The depth charges failed to release on the first run, and on a further two passes, possibly due to flak hits to 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 damage to the hydraulics and nose wheel. The damage was noticed, and F/O Irving managed to reach base and land without flaps or brakes at first light - for which he later received the DFC. (Sources: Franks/Zimmerman)
