The Battle of Oriskany, fought on August 6, 1777, was one of the bloodiest battles in the North American theater of the American Revolutionary War and a significant engagement of the Saratoga campaign. An American party trying to relieve the siege of Fort Stanwix was ambushed by a party of Loyalists and allies of several Native American tribes. This was one of the few battles in the war in which almost all of the participants were North American: Loyalists and allied Indians fought against Patriots and allied Oneida in the absence of British soldiers.

Early in the siege of Fort Stanwix, an American relief force from the Mohawk Valley under General Nicholas Herkimer, numbering around 800 men of the Tryon County militia, and a party of Oneida warriors, approached in an attempt to raise the siege. British commander Barry St. Leger authorized an intercept force consisting of a Hanau Jäger (light infantry) detachment, Sir John Johnson's King's Royal Regiment of New York, Indian allies from the Six Nations, particularly Mohawk and Seneca; and other tribes to the north and west, and Indian Department Rangers, totaling at least 450 men.
