18 Sep 1944
09.20 hrs, off Utvaer, Norway, inbound: the boat was attacked by eight Mosquitos on an anti-submarine strike mission. The formation consisted of two Tsetse Mosquitos (248 Sqdn RAF/E and O), four aircraft each carrying two Mark XI depth charges (248 Sqdn RAF/B, J, U and V) and two escorting fighters (RAF Sqdn 235/J and H). When U-275 attempted to dive she grounded at a depth of 9m (30 ft) and was strafed and bombed twice while half submerged. The bombs of one aircraft failed to release, and the 6pdr gun of another jammed during the second run, but six depth charges fell close to the boat and at least 11 hits were observed by the Tsetse Mosquitos, and numerous cannon hits by other aircraft. The Mosquitos left when a nearby coastal battery opened fire on them, observing the U-boat limping away with a list to port. (Sources: KTB U-275/ADM199-1786)
