The most notorious of them all was Butler's Rangers, led by John Butler, a wealthy New York landowner who recruited Loyalists and Indians from the Six Nations to fight the Americans. The story of Butler and his Rangers is the subject of this excerpt from the television series "Canada: A People's History."
