History

Mercer County is named for Continental Army General Hugh Mercer. It was founded in 1838 from surrounding counties and played a part in the American Revolutionary War. On the night of December 25, 1776, General George Washington led the American forces across the Delaware River to attack Hessian forces in Trenton. Washington followed up the assault with a surprise attack on General Charles Cornwallis' forces in the Battle of Princeton on the eve of January 2, 1777, eventually retaking the colony. The successful attacks built morale among the pro-independence colonists. General Hugh Mercer died in the Battle of Princeton.
