Battle Of Wyoming
The Battle of Wyoming was an encounter during the American Revolutionary War between American Patriots and Loyalists accompanied by Iroquois raiders that took place in Wyoming Valley, Pennsylvania, on July 3, 1778.
More than three hundred Patriots were killed in a battle followed by a massacre, in which the Iroquois raiders hunted and killed fleeing Patriots before torturing to death thirty to forty who had surrendered.
The Iroquois were primarily Seneca and Onondaga, and only a few Mohawk.
The British supplied their native allies with muskets and gunpowder and advised raids against civilian settlements, especially in New York, Kentucky, and Pennsylvania. Joint Iroquois-Loyalist attacks in the Wyoming Valley and at Cherry Valley in 1778 provoked Washington to send the Sullivan Expedition into western New York during the summer of 1779. There was little fighting as Sullivan systematically destroyed the Native American winter food supplies, forcing them to flee permanently to British bases in Quebec and the Niagara Falls area.
