The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Army Distinguished Service Medal to Lieutenant General Henry Harley “Hap” Arnold (ASN: 0-2255), United States Army Air Forces, for exceptionally meritorious and distinguished service in the performance of duties of great responsibility as Chief of the Air Corps from 29 September 1938 to 31 May 1941, as Deputy Chief of Staff for Air from 29 November 1940 to 8 March 1942, and as Chief of the Army Air Forces from 20 June 1941 to 8 March 1942. He performed the duties required by the office in a superior manner during the most strenuous and trying period in the history of the air arm. During this period, an Air Corps Program of Expansion and Procurement was inaugurated whereby the personnel of the Air Forces was increased in excess of a thousand per cent and the number of aircraft increased proportionately. A program of expansion and procurement of this magnitude demanded comprehensive planning, its execution required outstanding ability, foresight, and leadership, all of which were exhibited by Lieutenant General Arnold in a high degree. He impressed this high quality of leadership, so vitally needed during this period.
