Operation Chastise, the audacious RAF bombing raid that struck at the heart of industrial Germany on the 17th May 1943, brought catastrophic damage to the three dams that served the Ruhr Valley. Water and electricity supplies were disrupted in a key area of the manufacture of Germany's war munitions, and the consequences were disastrous. The German war effort was set back substantially, the Allies celebrated, and Dr. Barnes Wallis became a national hero as the designer of the famed 'bouncing bomb' that inflicted such damage.Considered from an Allied perspective, the Dambuster Raid was a triumphant success, not only of British engineering but also of pilot endeavor. View it from the German perspective however, and an entirely new story emerges. That is precisely what we have here. In this image—heavy publication, Helmuth Euler explores all facets of the operation in fascinating detail, offering a host of illuminating insights into this much—studied event of twentieth century history.
