This hard-to-find marker, with a plaque that reads “The Grave of John J. Peterson, Revolutionary War, Westchester Militia (1746 – 1850)” is the grave of a little-known African American soldier, who played a small but crucial role in a pivotal event of the war. On September 21, 1780, Peterson, along with Moses Sherwood, brought a cannon from Fort Lafayette at Verplanck’s Point to Croton Point. There they fired on the British frigate Vulture which was waiting to pick up Major John André, who at the time was plotting with American General Benedict Arnold for the surrender of West Point. The Vulture abandoned its river position, forcing the spy André to move overland on horseback. He was captured in Tarrytown a few days later carrying plans of West Point. André was hanged in the tiny Rockland County hamlet of Tappan on October 2, 1780. Today, the cannon used by the patriots sits in front of the Peekskill Museum. Sherwood is buried in Ossining’s Sparta Cemetery
