Formed by John Butler in 1777, Butler's Rangers was one of the most effective Loyalist units of the American Revolution. These fierce green coated soldiers with their Native allies struck the frontier settlements of New York, Pennsylvania, Kentucky and elsewhere. They destroyed settlements and much needed granaries, while at the same time diverting Continental troops needed in the east to face the main British army. Butler's Rangers: Wilderness Warriors of the American Revolution tells the story of these hard bitten Loyalists who fought a rugged war on the edge of the frontier. Often vilified in American histories of the war, the Rangers as noted by a prominent early Canadian historian, “were hard, fierce, and revengeful men, but it should be remembered that they lived in a stormy time, in a hard, fierce, and revengeful world.”
