Princeton Battlefield State Park
About
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.[3][4] This success, shortly after Washington's crossing of the Delaware River and capturing the troops at the Old Barracks in Trenton, helped improve American morale.
