Fort Lesley J. McNair

Fort Lesley J. McNair is a United States Army post located on the tip of Greenleaf Point, the peninsula that lies at the confluence of the Potomac River and the Anacostia River in Washington, D.C. To the peninsula's west is the Washington Channel, while the Anacostia River is on its south side. Originally named Washington Arsenal, the fort has been an army post for more than 200 years, third in length of service, after the United States Military Academy at West Point and the Carlisle Barracks. The fort is currently named for General Lesley J. McNair, who was killed in action in World War II.

The military reservation was established in 1791, on about 28 acres at the tip of Greenleaf Point. Major Pierre Charles L'Enfant included it in his plans for Washington, the Federal City, as a major site for the defense of the capital. On L'Enfant's orders, Andre Villard, a French follower of Marquis de Lafayette, placed a one-gun battery on the site. In 1795, the site became one of the first two United States arsenals.
