28 May 1940
The boat missed the British steam merchant Alca with a torpedo and then opened fire with the deck gun southwest of Lands End. The steamer returned fire, but neither side scored any hits and the boat soon broke off the attack. (Sources: Ritschel)
30 Nov 1941
After sinking 2 British merchants from convoy OS-12 the boat was driven under and depth charged for several hours, but managed to escape unharmed. (Sources: Blair, vol 1, page 409)
19 Jul 1943
21.25 hrs, Bay of Biscay, outbound: U-43 and U-403 were attacked by British Liberator Mk.V BZ772 (RAF Sqdn 86/J, pilot F/L W. Roxburgh, DFC). U-403 immediately began to dive, covered by U-43, which fought off a first attack and then dived too. The aircraft suffered some damage and one of the crew was wounded, but the pilot nevertheless dropped two Fido homing torpedoes into the wash and observed a possible hit. Both boats were unharmed, and apparently misinterpreted the sounds of detonation as a crashing aircraft. The Germans claimed to have shot down the aircraft but it returned to base. (Sources: Franks/Zimmerman)
7 recorded attacks on this boat.
