Attacks on this boat and other events

1 Aug 1943
The sinking of U-383 20.02 hrs, Bay of Biscay, outbound: British Sunderland flying boat JM678 (228 Sqdn RAF/V, pilot F/L S. White), despite being hit by flak during an initial attack run, returned to drop seven depth charges, straddling the U-boat from the starboard quarter. The Sunderland then left to return to base, since flak hits had holed the hull and shot away the starboard float and aileron.

U-383 was last seen by the aircraft with a heavy list to port and men jumping overboard. Kremser reported to BdU that they were unable to dive and the boat was out of control. U-218, U-454 and U-706 were ordered to give assistance, with air cover and an escort of three torpedo boats promised the following day. However, U-454 had been lost earlier that day, and U-218, despite hearing the attack from nearby, was unable to locate U-383 in the darkness. The search continued the next day, but both U-boats were attacked by aircraft, and the torpedo boats searched the area without sighting anything. U-383 had apparently foundered during the night.
