Add a touch of reality to your Revolutionary War history lesson with a visit to Fort Griswold Battlefield State Park, site of the 1781 massacre led by the traitorous Benedict Arnold.

This is the historic site where, on September 6, 1781, British Forces, commanded by the infamous Benedict Arnold, captured the Fort and massacred 88 of the 165 defenders stationed there. The Ebenezer Avery House which sheltered the wounded after the battle has been restored on the grounds. A Revolutionary War museum also depicts the era. Fort Griswold was designated as a state park in 1953.

Fort Griswold Battlefield State Park is a stop on the Thames River Heritage Park Water Taxi route. The Water Taxi offers an exciting, affordable, and fun trip across the Thames River between New London and Groton on Fridays, Saturdays, and Sundays during the summer, with special sunset tours, in season. The three taxi stops are at the New London City Pier, Fort Trumbull and Fort Griswold landings which bring excitement and endless photo opportunities.
History of the Area
Located in Groton, Connecticut, the site was originally a fortification during the American Revolutionary War. Named after then Governor Matthew Griswold, it played an important role in defending against British forces.

On September 6th, 1781 - known as Battle of Groton Heights - British troops led by Benedict Arnold attacked and captured Fort Griswold. This resulted in heavy casualties for both sides but particularly devastating losses for Americans.

The state acquired this historic battlefield area around late-19th to early-20th century with preservation efforts starting from thereon. In 1953 it became officially recognized as a State Park.

Today visitors can explore restored earthwork batteries along with monuments commemorating those who fought here including Colonel William Ledyard's memorial monument erected on-site.

Connecticut has made state parks, forests, trails, historic sites and beaches more accessible to our residents so they can enjoy the many attractions and beauty they offer. Under the Passport to the Parks program, parking fees are now eliminated at Connecticut State Parks for those with Connecticut registered vehicles. You can view the CONNECTICUT PASSPORT TO THE PARKS web page to learn more.
