During the American Civil War on September 1, 1862, the Battle of Chantilly (or Ox Hill) was fought nearby.
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 (now U.S. Route 50) northwest of Centreville, Jackson turned southeastward toward Fairfax Court House (now the city of Fairfax) 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 Kearny near Ox Hill, west of Fairfax.
During the ensuing battle, which was fought amid a raging storm, both Union generals Stevens and Kearny 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, the small Ox Hill Battlefield Park preserves a 5-acre (20,000 m²) portion of the battle site.
