An American volunteer who joined the British Army before the United States entered World War I, he wrote with unusual immediacy about trench life and the strain of combat. His best-known book brings readers close to the mud, fear, boredom, and comradeship of the Western Front.

by Robert Derby Holmes
Robert Derby Holmes, often published as R. Derby Holmes, is best remembered for A Yankee in the Trenches (1918), a firsthand memoir of World War I. In the book and its front matter, he identifies himself as a corporal in the 22nd London Battalion of the Queen’s Royal West Surrey Regiment, and he explains that he wanted to give American readers a clear picture of trench life as he experienced it.
The story stands out because Holmes was an American writing from inside the British war effort before the United States entered the conflict. His account mixes battlefield danger with the routines of army life, creating a vivid, personal record rather than a distant history.
Reliable biographical details beyond his service and authorship are limited in the sources I found. What can be confirmed is that his reputation rests on this direct and readable wartime memoir, which has remained in circulation through public-domain and digital editions.
