 In an attempt to retain their sovereignty and remain an independent nation positioned between the new United States and British North America, four of the Iroquois Nations fought on the side of the British; only the Oneida and their dependents, the Tuscarora, allied themselves with the Americans.In retaliation for attacks on the frontier led by Joseph Brant and Loyalist Mohawk forces, the Sullivan Expedition of 1779 destroyed nearly 50 Iroquois villages, adjacent croplands and winter stores, forcing many refugees to British-held Niagara.As allies of the British, the Iroquois were forced out of New York, although they had not been part of treaty negotiations.
