BILL YENNE is the author of more than two dozen books on military and historical topics. The Wall Street Journal recently called his Indian Wars: The Campaign for the American West "splendid" and went on to say that it "has the rare quality of being both an excellent reference work and a pleasure to read." His other works include The American Aircraft Factory in World War II, Operation Cobra and the Great Offensive: Sixty Days that Changed the Course of World War II, Aces: True Stories of Victory and Valor in the Skies of World War II, Black '41: The West Point Class of 1941 and the American Triumph in World War II, and The History of the US Air Force. He is a member of the American Aviation Historical Society, and is a regular contributor to International Air Power Review. He worked with the legendary US Air Force commander, General Curtis E. LeMay, to produce Superfortress: The B-29 and American Airpower in World War II. He lives in San Francisco.
