Edward R. (Edward Royal) Coyle

Edward Royal Coyle was an American writer remembered for Ambulancing on the French Front, published in 1918. Library and public-domain records identify him as the author of that book and place it in the context of World War I ambulance work in France.

Accounts associated with the book describe him as one of the first Americans to serve as an ambulance man on the French front. That experience shaped a memoir focused less on military strategy than on what daily service felt like: movement under pressure, medical transport, and the human side of war.

Little else about his life is easy to confirm from the sources found here, so the safest picture is a simple one: a volunteer-turned-memoirist whose surviving reputation rests on a vivid personal record of wartime service.
