Max Arthur uses eyewitness testimonies to bring together this landmark oral history of Dambusters. In May 1943, nineteen Lancaster bomber crews of 617 Squadron took part in Operation Chastise. The raid used bouncing bombs to breach dam walls above the Ruhr industrial area in Germany, and was intended to flood the area and force Germany's defensive efforts away from the eastern Front. The first-hand accounts tell of the preparation, practice runs, planning and the raid itself, including the sense of emptiness and loss when eight of the aircraft failed to return.
