Cataclysm: General Hap Arnold and the Defeat of Japan


No published work examines General Henry H. "Hap" Arnold's role in depth during the Pacific War of 1944-1945, in the context of planning for the destruction of Japan. In this new study, Herman S. Wolk, retired Senior Historian of the U.S. Air Force, examines the thinking of Hap Arnold, Commanding General, Army Air Forces (AAF), during World War II. Specifically, Wolk concentrates on Arnold's leadership in crafting the weapons, organization, and command of the strategic bombing offensive against Japan, which culminated in Japan's capitulation in the summer of 1945, ending the Pacific War.

The narrative is, in a real sense, a sustained controversy over strategy, organization, and command in the war against Japan. The B-29 long-range bombing campaign against the Japanese home islands dictated unprecedented organization and command; hence, Arnold established the Twentieth Air Force, commanded by himself from Washington and reporting directly to the Joint Chiefs of Staff. This new type of bombing offensive-distinct in command, organization, range, and weapons from the European experience-also called for exemplary operational combat leadership in the field. Here Arnold excelled in his command of the AAF, relieving a long-time colleague (Hansell) in favor of a hard-nosed operator (LeMay). This crucial move was a turning point in the Pacific war.

In the spring and summer of 1945, Arnold was a driven leader, almost willing the B-29 campaign and the air and sea blockade to collapse Japan before the scheduled massive invasion of Kyushu on November 1st. It was a tense race against the invasion clock and the conviction of General George C. Marshall, Army Chief of Staff, that an invasion was absolutely necessary. Although the Soviet declaration of war on Japan was a factor in the Japanese surrender, it was the atomic bomb that politically shocked the Japanese to capitulation. Arnold, the architect of the bombing offensive, emphasized that Japan was already defeated in the summer of 1945 by the bombing and blockade and that it was not militarily necessary to drop the atomic bomb.

Wolk brings out important rationales and connections in doctrine, organization, and command not previously published. He also mines sources not previously exploited, including the author's interviews with General LeMay, Hansell, and Eaker; Arnold's wartime correspondence; documentation from the Franklin D. Roosevelt Library; and postwar interrogations of Japanese officials and civilians. Cataclysm will prove an important addition to the history of the Pacific War, airpower, and the debate over the use of the atomic bomb against Japan.


There have been books on the B-29 and works on Gen. Henry H. (Hap) Arnold, but not an analytical work that binds these two together and gets into the mind of Hap Arnold. This is what this book is all about. in the massive literature on the end of World War II in the Pacific, much attention has been given to the dropping of the atomic bombs on Hiroshima and Nagasaki. the fact, however, is that prior to August 1945 Japan had been defeated militarily, but was politically unwilling to surrender. a significant share of the credit for the hopeless situation of the Empire of Japan in the summer of 1945 must go to General Arnold, Commanding General, Army Air Forces (AAF) and Commander of the Twentieth Air Force, the global B-29 force in the Pacific. Arnold was an American original. Impetuous, never adverse to risk taking, he set goals that associates thought outlandish. Impatient, he drove himself, without regard to his health, plunging ahead like the proverbial bull in the China shop. Although he would certainly plead guilty to not being especially articulate, he frequently outwitted his adversaries on the strategic level and was a master at playing his cards close to his vest. Arnold was not a master . . .
