Attacks on U-228 during this patrol

7 May 1943
Aircraft attack, aircraft shot down:
British Halifax bomber HR792 (RAF Sqdn 58/A, pilot Sgt N.F. Robertson, RAAF)

10.50 hrs, Bay of Biscay, outbound: The Halifax was forced to break off an initial attack by heavy flak, but then made a strafing attack from the bow and released six depth charges, which overshot the boat and detonated about 25m (82ft) astern. The detonations gave U-228 a severe shaking and wounded the II WO and one seaman. The Germans observed several AA hits on the aircraft (misidentified as a Lancaster) and saw it emit smoke before they dived. The Halifax and its crew of seven failed to return to base and presumably crashed shortly after this attack.

8 Jul 1943
19.40 hrs, Atlantic W of Portugal: the boat was attacked by a British Catalina flying boat (RAF Sqdn 210/G, pilot F/O D.H. Clarke). The aircraft had used all its depth charges in an attack on U-641 two hours earlier, but made a strafing run on U-228 when she was spotted on the surface. Its gunners fired 240 rounds and saw hits all over the hull, while the Germans claimed to observe AA hits on the aircraft before they dived. They reported a Catalina probably shot down, but it was in fact undamaged. (Sources: Franks/Zimmerman)
