Carlisle Barracks is a United States Army facility located in Carlisle, Pennsylvania. The site of the U.S. Army War College, it is the nation's second-oldest active military base. The first structures were built in 1757, during the French and Indian War between Great Britain and France in the colonies. From 1879 to 1918, the property was transferred to the Department of Interior to operate the Carlisle Indian Industrial School. This was the first off-reservation boarding school established to educate and assimilate Native American children into European-American culture. In 1891 Congress passed legislation to expand this program. After the United States entered World War I, the school was closed and the property was transferred back to the War Department. 1756—1860 Developed at 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 that started in May 1757, during the French and Indian War on the North American front between the colonies of Britain and France. Colonel John Stanwix marched upstream with British regulars and provincials against the backdrop of the international Seven Years' War. After the American Revolutionary War, from 1783 to 1837, the town of Carlisle was significant as the frontier gateway, as a greatly increased wave of land-hungry migrants moved west. During the Revolutionary 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 at the time. The Hessian Powder Magazine, now Hessian Guardhouse Museum, was built in 1777. In 1794, Carlisle Barracks became the center of intense federal military activity with the outbreak of the Whiskey Rebellion in the Pennsylvania backcountry. President George Washington journeyed to the barracks to review the troops—perhaps as many as 10,000 men. The crisis was posed by farmers in southwestern Pennsylvania, who refused to pay a tax on the commercial whiskey they distilled from their corn crops. They had found the alcohol more easily transported east over the Alleghenies and more profitable to sell than was corn as grain. President Washington
