The Battle of Third Winchester (or Battle of Opequon) was fought in Winchester, Virginia on September 19, 1864 between Confederate Lt. Gen. Jubal Early’s Army of the Valley and Union Maj. Gen. Philip Sheridan’s Army of the Shenandoah in the American Civil War. The battle resulted in approximately 8,600 total casualties.
Like other battlefields in the Shenandoah Valley, the Third Winchester battlefield is a result of piecemeal purchases of private property, spurred by donations from preservationists. The Civil War Trust has preserved 222 acres of the 567-acre battlefield. The most recent acquisition was made in 2009 by the Shenandoah Valley Battlefields Foundation.
Third Winchester was the largest Civil War battle, in terms of importance and number of troops engaged, in the Shenandoah Valley. 40,000 Union soldiers fought 10–12,000 Confederates, with predictable results. The Union soldiers, however, were inexperienced and fighting Jubal Early’s veteran divisions. Despite losing the battle, the Confederates inflicted a disproportionate number of casualties.
