The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting a Bronze Oak Leaf Cluster in lieu of a Second Award of the Distinguished Service Cross to Captain (Air Service) Dogan Humphries Arthur, United States Army Air Service, for extraordinary heroism in action while serving with 12th Aero Squadron, U.S. Army Air Service, A.E.F., on October 18 and 30, 1918, while on artillery reglage. Lieutenant Arthur and his observer were attacked by four enemy planes. His observer’s guns were jammed, but Lieutenant Arthur, with splendid courage and coolness, outmaneuvered the hostile aircraft and escaped, although they followed his plane to within 25 meters of the ground, badly damaging it by machine-gun fire. On 30 October 1918, Lieutenant Arthur was one of a formation of nine planes which were to take photographs in German territory. Before the lines were reached six planes dropped out, but the remaining three entered the German lines, although they observed several large formations of enemy planes in the near vicinity. When they were 12 kilometers within the German lines they were attacked by 18 enemy Fokkers. Regardless of his own safety, Lieutenant Arthur engaged these planes in order to allow his companions to escape, and turning toward his own lines only when he saw them shot down. Then he fought his way home, and in the fight which ensued his observer shot down two enemy planes.
