The memoir of Shadrack Byfield, an English weaver and war amputee, occupies a privileged place in the historiography and public memory of the Anglo‑American War of 1812. Yet relatively little is known about the author of this rare rank-and-file account. Drawing on extensive archival research and a newly discovered second autobiography, this article challenges the familiar image of Byfield as a plainspoken exemplar of military stoicism. It reveals how war in North America transformed the former private soldier both physically and psychologically. Examining Byfield’s return to civilian life, the article highlights his tenacious pursuit of veterans’ benefits, his cultivation of influential patrons, and his invention of a prosthetic device to enable a resumption of weaving work. It also traces the ex‑serviceman’s path to publication and explores his shifting self‑presentation in print—first as a dutiful soldier and later as a redeemed sinner. Integrating scholarship on disability, memoirs, military welfare, and the history of emotions, the article argues that Byfield’s exceptionally well‑documented life offers a window into the wider experiences of Britain’s homecoming soldiers after the Napoleonic Wars.
