Chantilly, Virginia

Chantilly is an unincorporated place located in Fairfax County, Virginia. Recognized by the U.S. Census Bureau as a census designated place (CDP), the community had a total population of 41,041 as of the 2000 census.

Chantilly is home to Washington Dulles International Airport, which serves Washington, DC.

During the American Civil War on September 1, 1862, the Battle of Chantilly was fought here. Following his victory at the Second Battle of Bull Run (or Second Manassas), Confederate General Robert E. Lee directed Major General Thomas J. "Stonewall" Jackson to cross Bull Run on August 31 and sweep around the position of Major General John Pope's Union Army of Virginia at Centreville. Reaching the Little River Turnpike northwest of Centreville, Jackson turned southeastward toward Fairfax Court House (now Fairfax, Virginia) to strike in rear of Pope's army.

During September 1, Pope, apprised of Jackson's movement, began to withdraw toward Fairfax Court House. Late in the day, Jackson clashed with Union forces under Brigadier General Isaac Stevens and Major General Philip Kearney near Ox Hill, west of Fairfax. During the ensuing battle, which was fought amid a raging storm, both Union generals Stevens and Kearney were killed. The fighting ended at dusk, and Pope's army continued its withdrawal to Fairfax and subsequently to the Washington defenses.

Although commercial and residential development now covers most of the Chantilly (Ox Hill) battlefield, a small county park preserves a two-acre portion of the battle site.
