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) Joseph Frank Wehner, United States Army Air Service, for extraordinary heroism in action while serving with 27th Aero Squadron, 1st Pursuit Group, U.S. Army Air Service, A.E.F., near Rouvres, France, 15 September 1918. While on a mission First Lieutenant Wehner found an enemy patrol of eight machines attacking a single American observation machine. He immediately attacked, destroying one and forcing another down out of control, his own plane being badly damaged by enemy machine-gun fire. He managed to convey the American plane to safety.
