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. The Loyalist and Indian force ambushed Herkimer's force in a small valley about six miles east of Fort Stanwix. During the battle, Herkimer was mortally wounded. The battle cost the Patriots approximately 450 casualties, while the Loyalists and Indians lost approximately 150 dead and wounded. The result of the battle remains ambiguous because the apparent Loyalist victory was significantly affected by a sortie from Fort Stanwix in which the Loyalist camps were sacked, spoiling morale among the allied Indians.
