Operation Chastise was an attack on German dams carried out on the night of 16/17 May 1943 by 617 Squadron RAF Bomber Command, using special "bouncing bombs". The Möhne and Edersee dams were breached, however,  53 of the 133 aircrew who took part were killed, 3 captured, with 8 of the 19 Lancasters that took part were destroyed. Of the survivors, 34 were decorated at Buckingham Palace on 22 June, with Gibson awarded the Victoria Cross.
