Robert Graves first came across the name of Roger Lamb in 1914, when Graves was an English officer instructing his platoon in regimental history. Lamb was a British soldier who had served his king during the American War of Independence, and whose claim to a footnote in history is that he managed to escape twice from American prison camps. When Graves went to America in the 1930s, he remembered Sergeant Lamb, investigated his story and created this fictionalized memoir telling Lamb's story from his Irish childhood to war and revolution, weaving a mesmerizing tale of courage and adventure.
