History


Early history

The military reservation was established in 1791, on about at the tip of Greenleaf Point. Major
Pierre Charles L'Enfant Pierre "Peter" Charles L'Enfant (; August 2, 1754June 14, 1825) was a French-American artist, professor, and military engineer. In 1791, L'Enfant designed the baroque-styled plan for the development of Washington, D.C., after it was designated ...
included it in his plans for Washington, the Federal City, as a significant site for the capital defense. 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. An

after burning the Capitol. About 47 British soldiers found the powder magazines they had come to destroy were empty. Someone threw a match into the well, and "a tremendous explosion ensued," a doctor at the scene reported, "whereby the officers and about 30 of the men were killed and the rest most shockingly mangled." The remaining soldiers destroyed the arsenal buildings, but the facilities were rebuilt from 1815 to 1821. Eight buildings were arranged around a quadrangle and named the Washington Arsenal. In the early 1830s, four acres of marshland were reclaimed and added to the arsenal. A seawall and additional buildings were constructed. Between 1825 and 1831, the Washington Arsenal penitentiary, which was constructed adjacent to the main arsenal buildings, had a three-story block of cells, administrative buildings, and a shoe factory for teaching prisoners a trade. In 1857, the federal government purchased additional land for the site. By 1860, the arsenal had used one of the first steam presses, developed the first automatic machine for manufacturing percussive caps, and experimented with the Hale Rocket. A large civilian workforce manufactured ammunition at the arsenal, and the site included a large military hospital. File:Arsenal, Washington, D.C., north front.

, women worked in an ammunition factory at the Washington Arsenal as it served the Union. Many lower-class women—including Irish immigrants—needed wages, especially after male relatives went to war. Women were believed to have nimble fingers, attention to detail, and a tendency to neatness suitable for rolling, pinching, tying, and bundling cartridges with bullets and black powder. Wounded Civil War soldiers were also treated at the Arsenal in a hospital next to the penitentiary that was built prior to the war in 1857.


Accident

On 17 June 1864, fireworks left in the sun outside a cartridge room ignited, killing twenty-one women, many of whom burned to death in flammable hoop skirts. The War Department paid for their funerals, and President

assassinated Lincoln in retribution. Following Booth's death at the hands of Federal troops in Port Royal, Virginia, his conspirators were then apprehended and imprisoned in the Washington Arsenal penitentiary. After being found guilty by a military tribunal, four were hanged in the yard of the penitentiary, and the rest received prison sentences. Among those hanged at what would become Fort McNair was Mary Surratt, the first woman ever executed under federal orders. The military tribunal tried the conspirators in a complex that is known as Ulysses S. Grant Hall. This hall periodically holds public open houses. Each quarter of the hall is open to the public, and people can visit the courtroom and learn more about the trials.

20th century

From December 1901 to March 1903, Engineer officer Frederic Vaughan Abbot served on a panel that reported on the feasibility of establishing the United States Army War College at Washington Barracks and reconstructing the site so it could host the headquarters of the Chief of Engineers and the Engineer School. In 1904, the War College's first classes were conducted at Roosevelt Hall, the iconic building designed by the architectural firm of

Proposed buffer zone

In 2020, the Department of Defense and Army Corps of Engineers proposed a permanent restricted area of about 250 feet to 500 feet into the Washington Channel along the fort's western bank outlined by buoys and warning signs. This proposal was met with resistance from D.C. city leaders as it would limit access of up to half of the heavily used waterway. In January 2021, the NSA intercepted communications from the Iranian Revolutionary Guard that threatened mounting suicide boat attacks on Fort McNair similar to those used in the USS ''Cole'' bombing. The communications also revealed threats to kill Vice Chief of Staff of the Army General Joseph M. Martin and plans to infiltrate and surveil the installation. This contributed to calls to establish the buffer zone and continue increased security. During a March 2021 House Transportation & Infrastructure hearing on a bill prohibiting such a restriction on the Channel, it was noted that the rule, which did not propose the construction of a fence or blast wall, seemed designed to safeguard the views of "rich generals' houses".

The Inter-American Defense College is an advanced-studies institute for senior officers of the 25-member nations of the Inter-American Defense Board. Up to three students of the rank of colonel or the equivalent may be sent to the college by each member nation. The students' backgrounds must qualify them to participate in the solution of hemispheric-defense problems. The officers study world alliances and the international situation, the inter-American system and its role, strategic concepts of war, and engage in a planning exercise for hemispheric defense. The college has been at Fort McNair since 1962.

moved from rented offices in Washington, D.C., to Fort McNair in historically preserved quarters remodeled from its previous use as a commissary and before that as Fort McNair's stables. The center dated from the creation of the Army General Staff historical branch in July 1943 and the gathering of professional historians, translators, editors, and cartographers to record the history of World War II. That effort led to a monumental 79-volume series known as the "Green Books." Today, the center operates through four divisions. The histories division is the one most involved in writing the histories and providing historical research support to the Army staff. The field program and historical services guides work done at various posts and installations, as well as the work by deployed historical detachments for Army operations, ensures historical information is comprehensive and factual. Another division is responsible for overseeing the Army museum system and preserving artifacts and artwork that are the army's historical treasure. One such museum, The Old Guard Museum, was located at Fort Myer until it was closed.
