Attacks on this day
U-47. The boat fired a torpedo at the British battleship HMS Warspite, which missed (or more likely failed to detonate), and the boat was depth charged by destroyers. Date may be approximate (but before 19 April). (Blair, vol 1, page 154)
U-514. 03.49 hrs, Bay of Biscay, outbound: a British Wellington bomber (RAF Sqdn 172/S) strafed the boat and dropped two bombs. Shortly afterwards at 14.28, a British Whitley bomber (OTU Sqdn 10/H) located the boat and dropped four bombs. No damage from either attack. (Rohwer)
U-993. Aircraft attack, aircraft shot down:
British Liberator aircraft BZ945 (53 Sqdn RAF/O, pilot F/L L.M. Burton)
03.51 hrs, NW of Cape Finisterre, inbound: the B-24 strafed the boat in a Leigh Light attack and was hit by flak during the approach. It was observed to crash into the sea with one of the port engines on fire approx. 600m (1,968 ft) from the boat, exploding on impact and killing all 11 aircrew. Two depth charges and a small bomb dropped by the passing plane fell wide, causing no damage.(Franks/Zimmerman)
U-546. Aircraft attack, aircraft shot down:
British B-24 Liberator bomber BZ800 (RAF Sqdn 53/H, pilot F/L C. Roberts)
04.53 hrs, North of Finisterre, off the Bay of Biscay, inbound: after approaching using the Leigh Light, the Liberator dropped six depth charges, two to starboard and four to port of U-546 (which caused only minor damage) before the boat dived. The aircraft crashed into the sea 500m (1,640ft) from U-546. All nine aircrew died.(Franks/Zimmerman)
