After the Battle of Great Bridge, little military conflict took place on Virginia soil for the first part of the American Revolutionary War. Nevertheless, Virginia sent forces to help in the fighting to the North and South, including Daniel Morgan and his company of marksmen who fought in early battles in the north. Charlottesville served as a prison camp for the Convention Army, Hessian and British soldiers captured at Saratoga. Virginia also sent forces to its frontier in the northwest, which then included much of the Ohio Country. George Rogers Clark led forces in this area and captured the fort at Kaskaskia and won the Battle of Vincennes, capturing the royal governor, Henry Hamilton. Clark maintained control of areas south of the Ohio River for most of the war, but was unable to make gains in the Indian-dominated territories north of the river.
