On the 17th May 1943, nineteen Lancaster bomber crews gathered at a remote RAF station in Lincolnshire for a mission of extraordinary daring and high risk a night raid on three crucial and heavily defended dams deep in the German industrial heartland. The raiders would have to fly across occupied Europe at a perilously low level and drop their bombs at a mere 60 feet above the water to destroy the dam walls. Eight planes never returned. Bestselling author Max Arthur has collected together first-hand accounts of the preparation, practise, organisation and the raid itself, and the sense of emptiness and loss at RAF Scampton when 52 men failed to return. From RAF personnel and civilians to Germans who witnessed the raid, this landmark oral history collection paints a moving and personal picture of one of the most famous operations of the Second World War.
