The Battle of Oriskany was one of the bloodiest battles in the American Revolutionary War and a significant engagement of the Saratoga campaign. On August 6, 1777, a party of Loyalists and several hundred Indigenous allies across several nations ambushed an American military party that was marching to relieve the siege of Fort Stanwix. This was one of the few battles in which the majority of the participants were Americans; Rebels and allied Oneidas fought against Loyalists and allied Iroquois in the absence of British regular soldiers. There was also a detachment of Hessians in the British force, as well as Western Indians including members of the Mississauga people.
