Joseph S. (Joseph Shuter) Smith

Born in Philadelphia in 1893, Joseph Shuter Smith served during the First World War in the Canadian, British, and American forces. His memoir Over There and Back in Three Uniforms presents those experiences through the eyes of an American who crossed borders to fight, while Trench Warfare: A Manual for Officers and Men drew on his service as a second lieutenant with the British Expeditionary Force.

Smith wrote with directness and authority rather than flourish. His work is especially interesting because it combines two sides of wartime writing: the personal story of a soldier and the practical knowledge of an officer explaining how trench fighting really worked.

Reliable biographical details beyond his birth in 1893, his Philadelphia origin, his wartime service, and his authorship of these books are limited in the sources I could confirm. He is generally listed as having died in 1950.
