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) John Nace Jeffers, United States Army Air Service, for extraordinary heroism in action while serving with 94th Aero Squadron, 1st Pursuit Group, U.S. Army Air Service, A.E.F., over the region of Romagne, France, 5 October 1918. While on patrol Lieutenant Jeffers encountered ten enemy machines (Fokker type) at an altitude of 2,000 feet. Despite numerical superiority and by a display of remarkable courage and skillful maneuvering, he separated one of the planes from the formation, and after a brief encounter drove it down in flames.
