A detailed history of the American World War II bombing mission over Nazi Germany, by the author of The First Day on the Somme. On August 17, 1943, the entire strength of the American heavy bomber forces in England set out to raid two major industrial complexes deep in southern Germany: the Messerschmitt aircraft factory and the KGF ball bearing plant. For American commanders, it was the culmination of years of planning, the day when their self-defending formations of the famous Flying Fortress could at last perform their true role, reaching out by daylight to strike at targets in the deepest corners of industrial Germany. The day ended in disaster for the Americans. Thanks to the courage of the aircrews, the bombers won through to the targets and caused heavy damage, but sixty were shot down and the hopes of the American commanders were shattered. Historically, it was one of the most important days for the American air forces during the Second World War. While researching this catastrophic raid, author Martin Middlebrook interviewed hundreds of the airmen involved, German defenders, “slave workers,” and eyewitnesses. The result is a mass of fresh, previously unused material with which the author finally provides the full story of this famous day’s operations. Not only is the American side elaborated upon, but the previously vague German side of the story—both the Luftwaffe action and the civilian experiences in Schweinfurt and Regensburg—is also now presented clearly and in detail for the first time. Middlebrook also covers the important question of why the RAF did not support the American effort and follow up the raid on Schweinfurt as planned.
