The author of The First Day on the Somme recounts Operation Hydra, the British bombing on a Nazi army research center during World War II. On the night of August 17-18, 1943, RAF Bomber Command attacked a remote research establishment on the German Baltic coast. The site was Peenemunde, where Hitler’s scientists were developing both the V-1 flying bomb and the V-2 rocket whose destructive powers could have swung the course of the war. The raid was meticulously planned, and hopes were high. But the night sky was so cloudless that the British bombers presented an easy target for German night fighters, and over 40 were lost. Martin Middlebrook draws on the memories of over 400 people involved in the dramatic events on that night: RAF and Luftwaffe aircrew, German personnel at the research site, and foreign laborers who had been forced to work there. The result is a truly compelling account of this hazardous attempt to disrupt Hitler’s V-weapons program.
