Best known for a detailed regimental history of the First World War, this British officer wrote with the close-up perspective of someone deeply connected to the men and events he recorded. His work remains a useful window into the wartime experience of the 4th Battalion, The King's Own (Royal Lancaster Regiment).

by W. F. A. (Walter F. A.) Wadham, J. Crossley
Walter Francis Ainslie Wadham was a British Army officer and historical writer, usually credited as W. F. A. Wadham or Walter F. A. Wadham. Available records identify him as the author of The Fourth Battalion, The King's Own (Royal Lancaster Regiment) and the Great War, a book preserved by Project Gutenberg and attributed in its text to Walter F. A. Wadham.
Biographical references link him with Barrow-in-Furness in northwest England and describe him as a colonel, a former Mayor of Barrow, and a director of the Barrow Hematite Steel Company. Those same sources place his life roughly between 1865 and 1945.
His best-known book is a careful wartime chronicle rather than a conventional memoir. Written soon after World War I, it sets out to place the battalion's service on record, giving his writing a practical, eyewitness-adjacent quality that still appeals to readers of military history.
