The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pride in presenting the Army Distinguished Service Medal (Posthumously) to Brigadier General Asa North Duncan (ASN: 0-5142), United States Army Air Forces, for exceptionally meritorious and distinguished services to the Government of the United States, in a duty of great responsibility in the organization of the Third Air Support Command; the organization, training, and movement of the EIGHTH Air Force; the planning of the air components of two important task forces; and the movement of the TWELFTH Air Force, in 1942. The successful engagement of the enemy by the EIGHTH and TWELFTH Air Forces was made possible to a great degree by his foresight and efforts. His calm judgment, courage, resourcefulness, and superior leadership have been an inspiration to the armed forces and of great value to his country. The singularly distinctive accomplishments of General Duncan and his dedicated contributions reflect the highest credit upon himself and the United States Army.
