Dam Busters: The Race to Smash the German Dams

James Holland presents an analysis of the 1943 air attacks by the RAF, in which 19 Lancaster bombers ventured into the industrial heartland of Germany to destroy three heavily defended dams with the new bouncing bomb. James argues that the raid is the greatest of all time and explores whether its true impact has been underestimated - and if the result should have been even greater.
