Headquarters, European Theater of Operations, U.S. Army, General Orders No. 2 (January 10, 1944)
The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Distinguished Service Cross to Lieutenant Colonel (Air Corps), [then Major] Glenn Emile Duncan (ASN: 0-398671), United States Army Air Forces, for extraordinary heroism in connection with military operations against an armed enemy while serving as Pilot of a P-47 Fighter Airplane in Headquarters, 353d Fighter Group, EIGHTH Air Force, in aerial combat against enemy forces over enemy-occupied Europe while leading a group of fighter aircraft on 11 November 1943. As a result of leading a squadron of his group against a large number of enemy aircraft, Lieutenant Colonel Duncan became separated from his group. He observed enemy aircraft attacking bombers and, though at an unfavorable altitude and in the face of overwhelming odds, Lieutenant Colonel Duncan vigorously attacked the enemy aircraft, destroying one and dispersing the remainder. While proceeding to his home base, he observed four enemy aircraft attacking a straggling Fortress. Although his gas supply was dangerously low, he engaged the enemy and dispersed them, thereby saving the Fortress and its crew. The action of Lieutenant Colonel Duncan reflect the highest credit upon himself and the armed forces of the United States.
