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 Second Lieutenant (Infantry) John Lyon, United States Army, for extraordinary heroism in action while serving with 116th Infantry Regiment, 29th Division, American Expeditionary Forces, near Samogneux, France, 15 October 1918. During the attack on the Bois-de-la-Grande-Montagne, Lieutenant Lyon left a place of comparative safety to cross an open space, exposed to direct observation and fire from the enemy, to attempt a rescue of a wounded officer. He and two men who accompanied him were killed in this attempt.
