Windsor is a town in Broome County, New York, United States.

This area along the Susquehanna had long been settled by varying cultures of indigenous peoples, including those of the historic Iroquois Confederacy, who used the river for transportation, water and fishing.

Also an Iroquoian-speaking people, they had migrated from North Carolina, which they left because of warfare with English colonists and other tribes.

Joseph Brant used it as a base for his Volunteers, which fought with the British during the American Revolutionary War.

In retaliation for joint British and Iroquois raids on frontier communities, the Continental Army attacked and destroyed Onaquaga in October 1778.
