Book excerpt: Includes the Aerial Warfare In Europe During World War II illustrations pack with over 180 maps, plans, and photos. Gen Henry H. “Hap.” Arnold, US Army Air Forces (AAF) Chief of Staff during World War II, maintained diaries for his several journeys to various meetings and conferences throughout the conflict. Volume 1 introduces Hap Arnold, the setting for five of his journeys, the diaries he kept, and evaluations of those journeys and their consequences. General Arnold’s travels brought him into strategy meetings and personal conversations with virtually all leaders of Allied forces as well as many AAF troops around the world. He recorded his impressions, feelings, and expectations in his diaries. Maj Gen John W. Huston, USAF, retired, has captured the essence of Henry H. Hap Arnold—the man, the officer, the AAF chief, and his mission. Volume 2 encompasses General Arnold’s final seven journeys and the diaries he kept therein.
