Seneca people
The Seneca eventually supported the British during the American Revolution. Some Iroquois wanted to support Americans and others not. This conflict led to the division of the Iroquois Confederacy. Seneca fought with British in the Cherry Valley massacre and the Battle of Minisink. The Seneca and Iroquois had victories against the colonists from 1777 to 1778. In response, General John Sullivan (general) led a planned attack against the Iroquois. Sullivan and his troops destroyed villages and weakened the Iroquois. The Iroquois Confederacy fell apart.
