During the 18th century, the Seneca sided with the British Crown in most wars, including the American Revolutionary War. Seneca warriors were part of allied British-Iroquois raids against rebel colonial settlements in the Mohawk and Schoharie valleys; these attacks were led chiefly by Mohawk warriors under Joseph Brant. In retaliation, the Sullivan Expedition organized by American rebels swept through Iroquois country in western New York, destroying more than 40 Seneca villages, and their associated crops and winter stores. The surviving people fled to Canada, and many starved that winter.
