The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pride in presenting the Distinguished Service Cross (Posthumously) to First Lieutenant (Air Service) David Endicott Putnam, 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 Lachaussee, France, 12 September 1918. After destroying one of the eight German planes which had attacked him, Lieutenant Putnam was turning to our lines, when he saw seven Fokkers attack an allied biplane. He attacked the Germans and saved the biplane, but was himself driven down, shot through the heart.
