(1776–77) Engagements won by the Continental Army in the American Revolution .
Defeats in New York forced the army under George Washington to retreat through New Jersey into Pennsylvania. On Dec. 25, 1776, Washington led a force of 6,000 troops across the ice-filled Delaware River to surprise the 1,400-man British-Hessian force at Trenton, N.J., and captured 900 troops. A British force of 7,000 troops under Charles Cornwallis arrived to force the American army into retreat. At night Washington led his men around the British to defeat an outpost at Princeton, causing Cornwallis to retreat to New Brunswick and enabling Washington to lead his troops into winter quarters near Morristown. The victories restored American morale and renewed confidence in Washington.
