Princeton Battlefield State Park

(New Jersey)

The Princeton Battlefield in Princeton, Mercer County, New Jersey, United States, is where American and British troops fought each other on January 3, 1777, in the Battle of Princeton during the American Revolutionary War. The battle ended when the British soldiers in Nassau Hall surrendered. This success, following those at the Battle of Trenton on December 26, 1776, and the Battle of the Assunpink Creek the day before, helped improve American morale.
