American Revolutionary War - Northern and Western Frontier

Northern and Western Frontier

Further information: Western theater of the American Revolutionary War

West of the Appalachian Mountains and along the border with Quebec, the American Revolutionary War was an "Indian War". Most Native Americans supported the British. Like the Iroquois Confederacy, tribes such as the Shawnee split into factions, and the Chickamauga split off from the rest of the Cherokee over differences regarding peace with the Americans. The British supplied their native allies with muskets, gunpowder and advice, while Loyalists led raids against civilian settlements, especially in New York, Kentucky, and Pennsylvania. Joint Iroquois-Loyalist attacks in the Wyoming Valley in Pennsylvania and at Cherry Valley in New York 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 Indians' winter food supplies, forcing them to flee permanently to British bases in Quebec and the Niagara Falls area.

In the Ohio Country and the Illinois Country, the Virginia frontiersman George Rogers Clark attempted to neutralize British influence among the Ohio tribes by capturing the outposts of Kaskaskia and Cahokia and Vincennes in the summer of 1778, at which he succeeded. When General Henry Hamilton, the British commander at Detroit, retook Vincennes, Clark returned in a surprise march in February 1779 and captured Hamilton.

In March 1782, Pennsylvania militiamen killed about a hundred neutral Native Americans in the Gnadenhütten massacre. In the last major encounters of the war, a force of 200 Kentucky militia was defeated at the Battle of Blue Licks in August 1782.
