b. 1885
A mining engineer turned wartime memoirist, he wrote from firsthand experience about one of World War I’s most dangerous jobs: fighting underground beneath the trenches. His work stands out for its practical detail, steady nerve, and vivid sense of life at the front.

by H. D. (Harry Davis) Trounce
Born in 1885, Harry Davis Trounce was a British-born American mining engineer who is best known for Fighting the Boche Underground, a firsthand account of service in the tunnelling war of World War I. Library and public-domain catalog records identify him as H. D. (Harry Davis) Trounce and connect him with the 1918 publication of that memoir.
Accounts associated with later editions and recordings describe him as joining the British Army in October 1915 and serving with the 181st Tunnelling Company of the Royal Engineers in France and Flanders. That background helps explain the book’s strength: it reads less like distant history and more like a practical, close-up record of dangerous technical work under fire.
Beyond that core outline, reliable biographical detail is scarce in the sources I could confirm here. What is clear is that Trounce left behind a valuable personal narrative of an unusual corner of the war, one that still appeals to readers interested in military history, engineering, and eyewitness memoir.
