The American Revolution (1775-1783) saw the emerging nation's largest ever co-ordinated military action against Native Americans. Although now considered as a shameful episode in America's treatment of its native peoples, this massacre of the Iroquois militant forces was a pivotal turning point in the war - it forced many loyalists to flee into Canada, and sealed Britain's fateful decision to seek victory in the south - thus losing the war. "Year of the Hangman" is a riveting account of the events that surrounded this fateful campaign, and how it changed the outcome of the American Revolution.
