The Third Battle of Winchester, also known as the Battle of Opequon or Battle of Opequon Creek, was an American Civil War battle fought near Winchester, Virginia, on September 19, 1864. Union Army Major General Philip Sheridan defeated Confederate Army Lieutenant General Jubal Early in one of the largest, bloodiest, and most important battles in the Shenandoah Valley. Among the 5,000 Union casualties were one general killed and three wounded. The casualty rate for the Confederates was high: about 4,000 of 15,500. Two Confederate generals were killed and four were wounded. Participants in the battle included two future presidents of the United States, two future governors of Virginia, a former vice president of the United States, and a colonel whose grandson, George S. Patton, became a famous general in World War II.
After learning that a large Confederate force loaned to Early left the area, Sheridan attacked Confederate positions along Opequon Creek near Winchester, Virginia. Sheridan used one cavalry division and two infantry corps to attack from the east, and two divisions of cavalry to attack from the north. A third infantry corps, led by Brigadier General George Crook, was held in reserve. After difficult fighting where Early made good use of the region's terrain on the east side of Winchester, Crook attacked Early's left flank with his infantry. This, in combination with the success of Union cavalry north of town, drove the Confederates back toward Winchester. A final attack by Union infantry and cavalry from the north and east caused the Confederates to retreat south through the streets of Winchester.
Having sustained significant casualties and substantially outnumbered, Early retreated south on the Valley Pike to a more defendable position at Fisher's Hill. Sheridan considered Fisher's Hill to be a continuation of the September 19 battle and followed Early up the pike, where he defeated Early again. Both battles are part of Sheridan's Shenandoah Valley campaign that occurred in 1864 from August through October. After Sheridan's successes at Winchester and Fisher's Hill, Early's Army of the Valley suffered more defeats and was eliminated from the war in the Battle of Waynesboro, Virginia on March 2, 1865.
In August 1864, the American Civil War was in its fourth year, and the exploits of Confederate Lieutenant General Jubal Early caused considerable consternation among leaders of the federal government of the United States. Major General Philip Sheridan, commander of the new Middle Military Division, faced constant pressure to attack Early, but Lieutenant General Ulysses S. Grant warned Union leaders on August 12 that two divisions of infantry had joined Early, and that Sheridan "must be cautious and act now on the defensive" until Grant's actions near Richmond would cause those units to return to the Richmond area. The impending presidential election of 1864 made it necessary to avoid any military disaster that might hamper the re-election of President Abraham Lincoln. Sheridan kept his troops between Early's army and Washington, and fought several small battles—including the Battle of Berryville that ended September 4. After that battle, Early withdrew during the night to the west side of Opequon Creek between Berryville and Winchester, VirginiaSheridan's troops kept their same positions for the next few weeks, with daily cavalry probes including the capture of the 8th South Carolina Infantry Regiment by a cavalry brigade led by Brigadier General John B. McIntosh. Sheridan's tentativeness caused Early to believe Sheridan was a timid commander.
During September 1864, Sheridan sought information about Early's troop strength. His scouts discovered Thomas Laws, a slave with a permit to enter Winchester to sell produce, who agreed to carry messages. A schoolteacher named Rebecca Wright, who was living in Winchester, agreed to provide information on Early's troops. From a message written on September 16, Sheridan learned from Wright through Laws that a division of infantry and battalion of artillery, commanded by Major General Joseph B. Kershaw, had left the area to rejoin General Robert E. Lee's Army of Northern Virginia near Richmond or Petersburg. Given the information, Sheridan planned to send his infantry to Newtown on the next day, which would prevent a retreat south by Early. His plan was delayed when Grant directed Sheridan to meet him at Charlestown, and upon returning he changed his plan to accommodate Early sending two divisions to Martinsburg, West Virginia.
In Martinsburg, Early became aware of Grant's visit on the morning of September 18, and sent one division to Bunker Hill (slightly north of the halfway point between Winchester and Martinsburg) and the other division (with Early) further south to Stephenson's Depot on the north side of Winchester. Sheridan's final plan was to have cavalry divisions led by Brigadier General Wesley Merritt and Brigadier General William W. Averell attack from the north. From the east, a cavalry division led by Brigadier General James H. "Harry" Wilson would lead two infantry corps from Berryville eastward to attack Early's vastly-outnumbered force between Opequon Creek and Winchester. Crook's two divisions would be held in reserve until later, when they would occupy the Valley Pike on the south side of Winchester.
Union army commanded by Philip Sheridan
The Union force in the Third Battle of Winchester was the Army of the Shenandoah, which was re-created August 1, 1864, and commanded by Major General Philip Sheridan. At its creation, the army had three objectives. First, it was to drive Early's army away from the Potomac River region and lower (northern) Shenandoah Valley, and pursue it southward. Second, it would destroy the valley's capacity to provide Lee's Army of Northern Virginia with food and other goods. Third, it was to disrupt the Virginia Central Railroad.
In mid-September, the Army of the Shenandoah had ten divisions plus artillery units, totaling to about 40,000 men.
VI Corps had three divisions and an artillery brigade, and was commanded by Major General Horatio Wright. His fighters were considered reliable veterans. Wright's artillery consisted of six four-gun batteries of Napoleons and 3-inch rifles, which totaled to half of the artillery assigned to Sheridan's infantry.
XIX Corps, consisting of two divisions, was commanded by Brigadier General William H. Emory. Each of his divisions had its own artillery, plus more artillery was held in reserve. The XIX Corps were considered behind the VI Corps in discipline and efficiency.
The Cavalry Corps, consisting of three divisions and a section of horse artillery, was commanded by Brigadier General Alfred Torbert. Fifteen regiments of the cavalry were completely armed with the carbine version of the Spencer repeating rifle, which held seven cartridges in its magazine. Three more regiments were partially armed with the rifle version of the weapon, an advantage over single-shot firearms.
The Army of West Virginia functioned as an infantry corps in Sheridan's Army of the Shenandoah, and is sometimes incorrectly identified as the VIII Corps. It was commanded by Brigadier General George Crook, and had two divisions plus an artillery brigade. Crook was a professional soldier and Sheridan's roommate at West Point, and had a good grasp of military tactics. One of Crook's brigade commanders, Colonel Rutherford B. Hayes, later became President of the United States. A member of Crook's staff, Captain William McKinley, also became president two decades after Hayes.
Confederate army commanded by Jubal Early
The Confederate force was the Army of the Valley, which was created in June 1864 and commanded by Lieutenant General Jubal Early. This army was a detachment of the Army of Northern Virginia's Second Corps, and consisted of six divisions plus artillery. Its purpose was to protect the Shenandoah Valley, which was a major source of food for eastern Confederate armies. Another objective was to threaten the Union's capital of Washington, and cause it to devote resources to protect the capital and northern states—which would relieve some of the pressure on the Army of Northern Virginia near the Confederate capital of Richmond.
