Carlisle Barracks

Carlisle Barracks is a United States Army facility located in Carlisle, Pennsylvania. It is part of the United States Army Training and Doctrine Command and is the site of the U.S. Army War College. It is the nation's second-oldest active military base.Early historyAt the intersection of Indian trails along Letort Creek, in the eighteenth century the town of Carlisle became the jumping-off point for traders and settlers heading over the Alleghenies on their way west. A brief 1756 encampment at Carlisle preceded the more permanent settlement in May 1757, when Colonel John Stanwix marched upstream with British regulars and provincials during the Seven Years' War (also known as the French and Indian War). After the American Revolutionary War, from 1783–1837, the town of Carlisle was significant as the frontier gateway, as a greatly increased wave of land-hungry migrants moved west.During the war, numerous substantial brick buildings were erected at Carlisle Barracks for military stores and to accommodate workmen of the revolutionary government's dedicated managing body for the Army, the Ordnance Department. While the facility might have been used to store ammunition and explosives, its lack of access to water transportation made it impractical because of the difficulty of overland travel. The Hessian Powder Magazine, now Hessian Guardhouse Museum, was built in 1777.
