On the night of 16–17 May 1943, 617 Squadron despatched 19 Lancasters from Scampton. Led by Wing Commander Guy Gibson, the main bulk of the squadron attacked the Sorpe, Eder and Möhne dams with an additional aircraft tasked to perform an attack on the Schwelm Dam. Both the Eder and Möhne dams were breached, however eight of the Lancasters despatched failed to return and 53 aircrew were lost. Following the raid Wing Commander Gibson was awarded the Victoria Cross, becoming Scampton's third recipient of the award. On the day of the raid, Wing Commander Gibson's dog, Nigger, was run over and killed on the A15 outside the entrance to the base. He was buried later that night, his grave situated outside Gibson's office at No. 3 Hangar.
