Newtown Battlefield State Park, formerly known as Newtown Battlefield Reservation, was the site of the Battle of Newtown fought in August 1779, during the American Revolutionary War. It was the only major battle of the Sullivan Expedition, an armed offensive led by General John Sullivan that was ordered by the Continental Congress to end the threat of the Iroquois who had sided with the British in the American Revolutionary War. In the battle, the Iroquois were defeated decisively.
Because the present day battlefield is quite heavily wooded and obscured to the casual passerby on the highway below, a narrow column of white granite known as the Newton Battlefield Monument sits atop the hill where this historic battle once took place in Elmira, in Chemung County, New York. It was declared a National Historic Landmark in 1965.
