As the United States Third Army's tanks moved through Avranches, no one, not even the Third Army's commander, Lieutenant General George S. Patton, could have foreseen that it was the start of one of the most successful offensives of World War II--an offensive that received a great deal of help from the air. As Patton later wrote to the chief of the Army Air Forces, "For about 250 miles I have seen the calling cards of the fighter-bombers, which are bullet marks in the pavement and burned tanks and trucks in the ditches."

This book covers the units in the Ninth Air Force, which gave close air support to the Third Army, and the Third Army's campaign in France from August to November 1944, with special emphasis on how support from the air helped the Third Army continue pushing toward the German border. The difficult logistics of the operation are discussed in detail: Both the Ninth Air Force and the Third Army were hurt by a lack of materiel, especially gasoline, and this affected the offensive.
