The Jersey Brigade was formed in December 1775 under Colonel William "Scotch Willie" Maxwell. After having fought in the Battle of Springfield on June 23, 1780, the Jersey Brigade was sent to several posts to protect the New Jersey side of the Hudson from British incursions. In October they camped at West Point anticipating they would remain there for the winter, but instead were ordered to take up winter quarters in Pompton, New Jersey. Colonel William Maxwell resigned from service before the end of October 1780.
