Location of the battle in Virginia

The Battle of Cedar Mountain, also known as Slaughter's Mountain or Cedar Run, took place on August 9, 1862, in Culpeper County, Virginia, as part of the American Civil War. Union forces under Maj. Gen. Nathaniel P. Banks attacked Confederate forces under Maj. Gen. Thomas J. "Stonewall" Jackson near Cedar Mountain as the Confederates marched on Culpeper Court House to forestall a Union advance into central Virginia. After nearly being driven from the field in the early part of the battle, a Confederate counterattack broke the Union lines resulting in a Confederate victory. The battle was the first combat of the Northern Virginia Campaign.

On June 26, Maj. Gen. John Pope was placed in command of the newly constituted Union Army of Virginia. Pope deployed his army in an arc across Northern Virginia. Its right flank, under Maj. Gen. Franz Sigel, was positioned at Sperryville on the Blue Ridge Mountains, its center, under Maj. Gen Nathaniel P. Banks, was located at Little Washington and its left flank under Maj. Gen. Irvin McDowell was at Falmouth on the Rappahannock River. Part of Banks's corps, Brig. Gen. Samuel W. Crawford's brigade and Brig. Gen John P. Hatch's cavalry, were stationed 20 miles (32 km) beyond the Union line, at Culpeper Court House.
