Battle context
The Battle of Opequon, fought near Winchester, Virginia, on September 19, 1864, was one of the largest, bloodiest, and most important engagements in the Shenandoah Valley during the Civil War. Union Major General Philip Sheridan defeated Confederate Lieutenant General Jubal Early with a force of roughly 40,000 against an army of approximately 15,500, inflicting approximately 4,000 Confederate casualties — a rate that severely degraded Early's command. Union losses approached 5,018, including one general killed and three wounded; the Confederates lost two generals killed and four wounded. The scale and decisiveness of the Union victory marked a significant shift in Federal control over the Shenandoah Valley, a strategically vital corridor that had long served Confederate logistical and operational purposes. The battle drew a remarkable roster of participants, including two future U.S. presidents, two future governors of Virginia, a former U.S. vice president, and a colonel whose grandson would command Allied armor in World War II.
