Two major battles were fought on these rolling Virginia fields just 25 miles from Washington: First Bull Run in July 1861, the Confederacy's first major victory that dispelled Northern illusions of a short war, and Second Bull Run in August 1862, where Lee's decisive defeat of Pope's Army of Virginia set the stage for the invasion that ended at Antietam. The Henry Hill visitor center overlooks the ground where Stonewall Jackson earned his famous sobriquet.
