Attacks on U-645 during this patrol
12 Jun 1943
13.00 hrs, north of the Azores: British B-24 Liberator bomber FL932 (RAF Sqdn 86/H, pilot F/O C.W. Burcher, DFC, RAAF), escorting troop convoy TA 48 approached U-645 from the starboard bow and dropped five depth charges which overshot, the closest detonating 15m (49ft) astern and causing slight damage. Gunfire was exchanged for the next 30 minutes, with the U-boat claiming hits on the Liberator, but there was no significant damage and it returned to inform the convoy. (Sources: Franks/Zimmerman)
12 Jun 1943
16.23 hrs, north of the Azores: British B-24 Liberator bomber FK226 (RAF Sqdn 86/G, pilot F/O A.C.I. Samuel), escorting troop convoy TA 48 was forced to break off an intial attack run by heavy flak and then exchanged gunfire for 10 minutes before dropping five depth charges that detonated 50 to 100m (164-328 ft) to starboard of the boat. Flak hits to the fuselage, bomb bay and a fuel tank killed one man and started a fire which was quickly extinguished. The damage forced the aircraft to return to base, while the boat dived.
