Late on the evening of April 12, 1777, four thousand British and Hessian troops under the command of Lieutenant General Charles Cornwallis marched from the British stronghold of New Brunswick. All but one detachment reached positions surrounding the outpost before the battle began near daybreak the next morning. During the battle, most of the 500-man garrison escaped by the unblocked route. U.S. reinforcements arrived in the afternoon, but not before the British plundered the outpost and began the return march to New Brunswick.
