During the Revolutionary War, the Fishkill south of the village of Fishkill was a key location for the Continental Army. Troops were on continuous alert should the British Army try to push up through the Highlands to the south and retake the Hudson Valley, a move that could have cut the colonies in half. At the junction of two major overland routes, it was also the site of a key supply depot, and a large encampment of soldiers was located on on the south of the creek, about where the interchange of Interstate 84 and US 9 is located now. George Washington passed through the area frequently. In 2009 the graves of as many as 700 soldiers were discovered at the site.
