His commission as major was in the Manor of Livingston Regiment, and his appointment was prior to January 15, 1777, on which date he resigned in favor of Samuel Ten Broeck, and he probably succeeded his cousin, Henry Livingston, on that officer's promotion to lieutenant-colonel, in place of Robert R. Livingston. His commission as army agent for the purchase of clothing for the New York troops was dated October 3, 1776. He and Abraham P. Lott were appointed by the New York congress, and were allowed two and a half per cent. commission on their purchases. He had charge of a command of the Manor Regiment, as stated, and in August, 1777, did his utmost to move his soldiers to help General Schuyler at Bemis Heights, but his men were harangued by ringleaders, and he wrote to the chancellor, stating that they no longer considered the oath to the state binding.
