At Merritt Hill during the Battle of White Plains on October 28, 1776, as the British marched up the road to Connecticut, Lake Street, during the attack on Chatterton Hill to strike the left flank of George Washington’s defense assembled on Hatfield Hill opposite Merritt Hill, General Heath under Washington had placed Colonel Malcolm, his New York Regiment, and Lieutenant Fenno with one field piece on Merritt Hill in defense of Hatfield Hill. Fenno fired a cannonball directly into twenty British horsemen approaching Hatfield Hill, and this single shot caused the British to retreat back toward White Plains.
