On December 19th, 1777, 12,000 weary revolutionary war soldiers and 400 women and children marched into what would be their winter encampment. They began to build what was essentially the fourth largest city in the United States, with 1,500 log huts and two miles of fortifications. Lasting six months, from December until June, the encampment was as diverse as any city, with people who were free and enslaved, wealthy and impoverished, speakers of several languages, and adherents of multiple religions. Concentrating the soldiers in one vast camp changed the face of the conflict, leading to the long-fought independence the colonies so desired.
