A rigorous new analysis of America's legendary 'Big Week' air campaign which enabled the Allies to gain air superiority before D-Day. The USAAF's mighty World War II bomber forces were designed for unescorted, precision daylight bombing, but no-one foresaw the devastation that German radar-directed interceptors would inflict on them. Following the failures of 1943's Schweinfurt-Regensburg raids, and with D-Day looming, the Allies urgently needed to crush the Luftwaffe's ability to oppose the landings. In February 1944, the Allies conceived and fought history's first-ever successful offensive counter­air (OCA) campaign, Operation Argument or "Big Week." Attacking German aircraft factories with hundreds of heavy bombers, escorted by the new long-range P-51 Mustang, it aimed both to slash aircraft production and force the Luftwaffe into combat, allowing the new Mustangs to take their toll on the German interceptors. This expertly written, illustration-packed account explains how the Allies finally began to win air superiority over Europe, and how Operation Argument marked the beginning of the Luftwaffe's fall. The book is wonderfully supplemented by the usual stunning artwork known in many of the Osprey series. There are excellent maps, orders of battle, and a good selection of photographs. I found few if any editing errors in this book. It is a fantastic look at a very focused and short campaign in February 1944 that was deemed crucial to the success of the impending Allied invasion. In fact by April 1944, the USAAF switched priorities and focus by being subordinated to Eisenhower for invasion support. If you are looking for a compact yet comprehensive and affordable look at Operation Argument, then this is the book for you.
