Fort Mercer
National Park, NJ
Fort Mercer was one of two forts constructed in 1777 on the Delaware River during the
American Revolutionary War, by the Continental Army, under the command of George
Washington, to block the approach to Philadelphia, Pennsylvania: Fort Mifflin, on the
Pennsylvania side, and Fort Mercer, on the New Jersey side. Fort Mercer was located in
what is now National Park, New Jersey. A park, monument, and museum exist today on
the site of the fort. The fort was named in honor of Brigadier General Hugh Mercer who
had died earlier that year at the Battle of Princeton.

On October 22 of that year, in what is known as the Battle of Red Bank, an attack by 900
Hessian troops, serving under British Major General William Howe, who then occupied
Philadelphia, was repelled, with heavy losses on the Hessian side, including the death of
their commander, Colonel Carl Emil Kurt von Donop, by the 600 Continental defenders
under Colonel Christopher Greene. After the later loss of Fort Mifflin, Fort Mercer was
abandoned without a fight when Lord Charles Cornwallis landed 2,000 British troops
nearby on November 18, 1777.
