Overview

The Battle of Chantilly took place on September 1, 1862, in Fairfax County, Virginia, as the concluding battle of the Northern Virginia Campaign of the American Civil War. Thomas J. "Stonewall" Jackson's corps of the Army of Northern Virginia attempted to cut off the line of retreat of the Union Army of Virginia following the Second Battle of Bull Run, but was attacked by two Union divisions. During the ensuing battle, Union division commanders Isaac Stevens and Philip Kearny were both killed, but the Union attack halted Jackson's advance.

Significance

Chantilly closed the Northern Virginia Campaign of 1862 as a Confederate effort to exploit the Union defeat at Second Bull Run. Following that engagement, Stonewall Jackson's corps moved to cut off the Army of Virginia's retreat, threatening to turn a tactical defeat into a strategic catastrophe for Union forces in the region. Two Union divisions attacked Jackson's advance before it could succeed, halting the Confederate flanking movement and allowing the Union army to withdraw intact. The cost was steep: both division commanders Philip Kearny and Isaac Stevens were killed in the fighting, representing a significant loss of senior leadership for the Union. The battle did not reverse the outcome of the Northern Virginia Campaign, but it foreclosed Jackson's attempt to deepen the damage, leaving the Union army battered but able to fall back toward Washington rather than face encirclement or further destruction.
