Howe launched his attack on November 16. He led an assault from three sides: the north, east and south. Tides in the Harlem River prevented some troops from landing and delayed the attack. When the British moved against the defenses, the southern and western American defenses fell quickly. Patriot forces on the north side offered stiff resistance to the Hessian attack, but they too were eventually overwhelmed. With the fort surrounded by land and sea, Colonel Magaw chose to surrender. A total of 59 Americans were killed in action and 2,837 were taken as prisoners of war.
