Princeton JunctionOfficially founded in 1838 and carved out of other surrounding counties, Mercer County has a historical impact that reaches back to the pivotal battles of 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, New Jersey, who did not anticipate an attack near
Christmas. 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.
Mercer County also has the dubious distinction of being the famed landing spot for a Martian invasion of the United States. In 1938, in what has become one of the most famous radio addresses of all time,
Orson Welles acted out his
War of the Worlds invasion. Wells landed his imaginary aliens on Mercer County soil, using what is now
West Windsor Township as the point of first contact.
