|John Lyon's 1915 passport photo|
John attended Western High School, the University of Virginia and Georgetown Law School. He also worked as an associate editor for Field and Stream magazine. John applied in 1915 for his passport so that he could go to Great Britain and "do hospital work" but drove ambulances for the Red Cross in France.
After 6 months in France he returned to the U.S. and joined a local National Guard unit and served in the Mexican Border service. It is likely that he was the most combat experienced of any in his company. He was still a member of the unit when it was federalized in 1917 and then assigned to Machine Gun Company 116th Infantry. After participating in the training at Camp McClellan, Alabama he traveled with the unit aboard the USS Finland to France. The ship docked at the port of Saint Nazaire on 28 Jun 1918. After the unit went through the trench warfare training and a period of acclimatization in a "quiet" sector on the front lines it was part of a major offensive in the vicinity of Verdun. On 16 Oct 1918 the unit was involved in fighting when the commander of the 3rd Battalion, MAJ Heriome Opie was wounded. 1LT Lyon was killed in action when he tried to help MAJ Opie.
1LT Lyon was posthumously awarded the Distinguished Service Cross in 1919. This is the citation:
John Lyon, first lieutenant, Machine Gun Company, 116th Infantry, Twenty-ninth division. For extraordinary heroism in action near Damogneux, France, October 15, 1918.
