17 Oct 1943
Aircraft attack, aircraft shot down: Canadian Sunderland JM712 (RCAF Sqdn 422/S, pilot F/L P.T. Sargent)
At 12.48 hours the Sunderland attacked U-448 after obtaining a radar contact near convoy ONS-20. U-281 was nearby and assisted by firing at the aircraft with its AA guns during the first attack run. The four depth charges dropped fell short, so the aircraft turned around for a second attack, exchanging gunfire with both boats. The Sunderland then dropped two depth charges on U-448, but suffered heavy damage from flak, which killed the nose gunner and mortally wounded the navigator. The pilot had to ditch in heavy seas near the convoy. He and two aircrew died in the crash, but the remaining seven were picked up by HMS Drury. U-448 was seriously damaged by the last two depth charges and was forced to abort her patrol. Strafing killed one crewman and wounded two. [Oberbootsmaat Fritz Döhler] (Sources: Franks/Zimmerman)
