The Battle of Princeton was a battle of the American Revolutionary War, fought near Princeton, New Jersey on January 3, 1777. Lieutenant General Charles Cornwallis had left 1,400 British troops under the command of Lieutenant Colonel Charles Mawhood in Princeton. Following a surprise attack at Trenton early in the morning of December 26, 1776, General George Washington of the Continental Army decided to attack the British in New Jersey before entering winter quarters. On December 30, he crossed the Delaware River back into New Jersey. His troops followed on January 3, 1777. Washington advanced to Princeton by a back road, where he pushed back a smaller British force but had to retreat before Cornwallis arrived with reinforcements. The battles of Trenton and Princeton were a boost to the morale of the Continental troops, leading many recruits to join the Continental Army in the spring.

Alexander Hamilton participated in the Battle of Princeton on January 3, 1777. After an initial setback, Washington rallied the American troops and led them in a successful charge against the British forces. After making a brief stand, the British fell back, some leaving Princeton, and others taking up refuge in Nassau Hall. Hamilton brought three cannons up and had them fire upon the building. Then some Americans rushed the front door, and broke it down. The British subsequently put a white flag outside one of the windows; 194 British soldiers walked out of the building and laid down their arms, thus ending the battle in an American victory.
