Attacks on this boat
16 Nov, 1939
After sinking the British vessel Arlington Court from convoy SL 7 convoy escorts hunted the boat for 20 hours severely damaging her (they also hunted U-41 at the same time). (Sources: Blair, vol 1, page 119)
22 Nov, 1939
After a successful attack on the French convoy 14-BS, the boat was attacked by the escorts with 23 depth charges. No damages.
(Sources: Ritschel)
22 Apr, 1940
The U-43 was attacked in the North Sea by two Hudson aircraft with bombs and suffered slight damage.
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 sides scored hits and the boat soon broke off the attack. (Sources: Ritschel)
30 Nov, 1941
After having sunk 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
At 21.25 hours, two outbound boats (U-43 and U-403) were attacked by the British Liberator Mk.V BZ772 (86 Sqdn RAF/J, pilot F/L W. Roxburgh, DFC) in the Bay of Biscay. U-403 immediately began crash-diving covered by U-43, which fought off a first attack and then dived too. AA fire slightly damaged the Liberator and wounded a crewman, but the pilot nevertheless dropped two Fido homing torpedoes into the swirl and observed a possible hit. Both boats were not hit and apparently misinterpreted the sounds heard as a crashing aircraft. The Germans claimed the Liberator as shot down, but it safely returned to base. (Sources: Franks/Zimmerman)
6 recorded attacks on this boat.
