Manhattan was at the heart of the New York Campaign, a series of major battles in the early American Revolutionary War. The Continental Army was forced to abandon Manhattan after the Battle of Fort Washington on November 16, 1776. The city, greatly damaged by the Great Fire of New York during the campaign, became the British military and political center of operations in North America for the remainder of the war. The military center for the colonists was established in New Jersey. British occupation lasted until November 25, 1783, when George Washington returned to Manhattan, as the last British forces left the city.
