 The last raid on Bristol was on 15 May 1944.Bristol was in danger of being hit by V-1 flying bombs, and by the A4/V2 rockets, whose launching platforms had already been built on the Cotentin peninsula in France in 1944.However, the Allied invasion of Normandy on 6 June 1944 saw these launching platforms on Cotentin being quickly overrun and consequently no V1 or V2s landed on Bristol.
