Attacks on this day


U-608. Aircraft attack, aircraft shot down:
British Wellington MP813 (RAF Sqdn 172/K, pilot F/S L.D. Richards)

This attack by a British Wellington bomber during the night of 30/31 Jan. 1944 in the Bay of Biscay west of Bordeaux, France in position 45.25N, 05.15W was formerly credited with the sinking of U-364 with depth charges.

The target was in fact the outbound U-608, which escaped unscathed. The boat scored hits on the aircraft with AA fire when it switched on the Leigh Light and then escaped by diving. The Wellington did not drop any depth charges, and apparently crashed shortly afterwards, as witnessed by a Polish-crewed Wellington (RAF Sqdn 304/2B, F/S S. Czekaski), who apparently misinterpreted the crash as exploding depth charges. The six aircrew were all lost.

(Axel Niestle, Franks/Zimmerman)
