The Battle of McDowell, also known as the Battle of Sitlington's Hill, was fought on May 8, 1862, near McDowell, Virginia, as part of Confederate Major General Stonewall Jackson's 1862 Shenandoah Valley campaign during the American Civil War. After suffering a tactical defeat at the First Battle of Kernstown, Jackson withdrew to the southern Shenandoah Valley. Union forces commanded by Brigadier Generals Robert Milroy and Robert C. Schenck were advancing from what is now West Virginia towards the Shenandoah Valley. After being reinforced by troops commanded by Brigadier General Edward Johnson, Jackson advanced towards Milroy and Schenck's encampment at McDowell. Jackson quickly took the prominent heights of Sitlington's Hill, and Union attempts to recapture the hill failed. The Union forces retreated that night, and Jackson pursued, only to return to McDowell on 13 May. After McDowell, Jackson defeated Union forces at several other battles during his Valley campaign.

Thomas Jonathan "Stonewall" Jackson was a general officer in the Confederate States Army during the American Civil War. He played a prominent role in nearly all military engagements in the Eastern theater of the war until his death. Military historians regard him as one of the most gifted tactical commanders in U.S. history.
