When the Revolutionary War came to New York, the British had the upper hand. General George Washington and troops from his Continental Army camped on the high ground, calling it Fort Washington, to monitor the advancing Redcoats. The Continental Army retreated from its location after their defeat on November 16, 1776, in the Battle of Fort Washington. The British took the position and renamed it Fort Knyphausen in honor of the leader of the Hessians, who had taken a major part in the British victory. Their location was in the spot now called Bennett Park. Fort Washington had been established as an offensive position to prevent British vessels from sailing north on the Hudson River. Fort Lee, across the river, was its twin, built to assist in the defense of the Hudson Valley.
