In November of 1776 the British gained control of New Jersey and forced Washington to flee into Pennsylvania. They thought no one would fight during winter, so the British and Hessian soldiers in New Jersey divided into camps to stay until spring. Trenton was considered the most desirable post, and it went to the Hessian soldiers as a reward for their good service. The Hessians used the Old Barracks in Trenton as a headquarters.
