On 17th May 1943 nearly 350 million tonnes of water crashed into the valleys of the Ruhr, when the Lancasters of 617 Squadron breached the giant Moehne and Eder Dams with colossal ‘blockbuster’ bombs. “The Dam Busters” is the story of that raid and the squadron who carried it through. It tells how they took out the V3 rocket weapon and destroyed the “Tirpitz” in a Norwegian fjord. Again and again, the crews of 617 Squadron Bomber Command used their flying skills, their tremendous courage and Barnes Wallis’ highly accurate bombs to deal devastating blows to Nazi Germany. This story is one of the classics of the Second World War, a massive bestseller that became a film.
