At approximately noon, on September 19, 1864, General Early survived a surprise attack by General Sheridan and his forces near Winchester. Early, in a victorious mood, even turned the tables on the attackers and attacked them. Much to his surprise at three o'clock of the same day, Sheridan returned and badly defeated Early, driving him back to Winchester and eventually to a retreat up the Shenandoah Valley. Sheridan, whose forces had been savagely attacked by some Confederate guerilla bands, now retaliated by destroying houses, barns and foodstuffs and by capturing or killing livestock. The valley was completely devastated by his destructive campaign. One month later, however, Early made a surprise crossing of a branch of the Shenandoah River and drove the forces of Sheridan northward from Cedar Creek in Frederick County. As Sheridan and his forces were fleeing, Union reenforcements arrived under the leadership of General Horatio Wright. The combined forces of Sheridan and Wright attacked the troops of Early and drove them from the area in great chaos. This victory was the shortest victory in the War between the States. During the war, several attempts had been made by the Union forces in the Shenandoah Valley to capture and destroy the Salt Works at Saltville, located in southwestern Virginia. In 1864, the Confederate General John H. Morgan with a small cavalry force successfully repulsed a Union force under General William Averell. On December 18, 1864, however, the salt mines and the Salt Works were destroyed by a small detachment of Union forces who were ordered to Saltville while the Confederates were engaged in severe fighting with the major Union troops at nearby Marion. The destruction of the Salt Works was significant because this location had furnished the principal source of salt supply for the Confederacy.
