From Wikipedia: "Lochry's Defeat, also known as the Lochry massacre, was a battle fought on August 24, 1781, near present-day Aurora, Indiana, in the United States. The battle was part of the American Revolutionary War (1775–1783), which began as a conflict between Great Britain and the Thirteen Colonies before spreading to the western frontier, where American Indians entered the war as British allies. The battle was short and decisive: about one hundred Indians of local tribes led by Joseph Brant, a Mohawk military leader who was temporarily in the west, ambushed a similar number of Pennsylvania militiamen led by Archibald Lochry. Brant and his men killed or captured all of the Pennsylvanians without suffering any casualties."
