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 First Lieutenant (Air Service) Robert Opie Lindsay, United States Army Air Service, for extraordinary heroism in action while serving with 139th Aero Squadron, 4th Pursuit Group, U.S. Army Air Service, A.E.F., near Bantheville, France, 27 October 1918. In company with two other planes, Lieutenant Lindsay attacked three enemy planes (Fokker type) at an altitude of 3,000 meters, and after a sharp fight brought down one of them. While engaged with the two remaining machines, eight more planes (Fokker type) came at him from straight ahead. He flew straight through their formation, gained an advantageous position, and brought down another plane before he withdrew from the combat.
