The significance of the Trenton and Princeton Campaign in the American Revolutionary War lies in its strategic and morale-boosting victories for the Continental Army. After a series of defeats, General George Washington led his troops across the icy Delaware River, achieving a surprise attack on the Hessian garrison in Trenton on December 26, 1776. This victory was followed by another key battle in Princeton on January 3, 1777, where American forces defeated British troops. These victories revitalized American morale, encouraged enlistment, and demonstrated Washington’s leadership. They shifted the tide of the war, showing that the Continental Army could win against formidable opponents.
