The Battle of Moorefield was a cavalry battle in the American Civil War, which took place on August 7, 1864. The fighting occurred along the South Branch of the Potomac River, north of Moorefield, West Virginia, in Hardy County. The National Park Service groups this battle with Early's Washington Raid and operations against the B&O Railroad, and it was the last major battle in the region before General Philip Sheridan took command of Union troops in the Shenandoah Valley. This Union triumph was the third of three major victories for Brigadier General William W. Averell, who performed best when operating on his own.
