The Type IXC boat U-518 left Lorient on 24 June 1943, under the command of Kapitanleutnant Friedrich-Wilhem Wissmann, but three days later it was spotted by Sunderland G.R.Mk.111 (W6005) of No.201 Sqd, flown by Flying Officer Brian E.H. Layne (RNZAF), from Castle Archdale, Northern Ireland. Two depth charges were dropped and the U-boat submerged. It reappeared a few minutes later and entered into a gun battle, as shown here, before submerging again. It reached Bordeaux on 3 July, seriously damaged. It was sunk on its seventh war cruise, about 400 miles west-north-west of the Azores, on 22 April 1943, by the destroyers USS Carter and Neal. There were no survivors from the crew of fifty-six.
