Army of the Shenandoah (Union)
The Army of the Shenandoah was a field army of the Union Army active during the American Civil War. First organized as the Department of the Shenandoah in 1861 and then disbanded in early 1862, the army became most effective after its recreation on August 1, 1864 under the command of Philip Sheridan. The army's actions during the Valley campaigns of 1864 rendered the Shenandoah Valley of Virginia unable to produce foodstuffs for the Confederate States Army, a condition which would hasten the conclusion of the American Civil War. History 1861–2 Under the command of Major General Robert Patterson before the three-month enlistments of a majority of its troops expired, the Department of Pennsylvania operated as the lone element of Union Army in the Shenandoah Valley of Virginia. After achieving a tactical victory at the Battle of Hoke's Run on July 2 and contributing indirectly to the Union disaster at the First Battle of Bull Run on July 21, its unexpired regiments and commanders were absorbed into a new Department of the Shenandoah under the command of Major General Nathaniel P. Banks on July 25, 1861. Neither Patterson nor Banks referred to his commands as the Army of the Shenandoah in official correspondence, and when the Army of the Potomac adopted a Corps structure on March 18, 1862, Banks' command was redesignated as the "Fifth Corps." 1864 On May 21, 1864, Major General David Hunter was appointed to command the Department of West Virginia. Hunter designated the field forces of his department the "Army of the Shenandoah". Hunter was in command of the Army of the Shenandoah from May 21 to July 3 which consisted of two infantry divisions and two cavalry divisions. The First and Second Infantry Divisions were commanded by Brigadier Generals Jeremiah C. Sullivan and George Crook respectively. The First and Second Cavalry Divisions were commanded by Brigadier Generals Julius Stahel (succeeded by Alfred N. Duffie) and William W. Averell respectively. In May Crook's and Averell's divisions fought independently at the battle of Cloyd's Mountain. Hunter personally led Sullivan's and Stahel's divisions at the battle of Piedmont. All four divisions were joined for the battle of Lynchburg. On July 3, George Crook assumed command of both infantry divisions and designated this as a new field army named the Army of the Kanawha. The force was next created by order of Ulysses S. Grant on August 1, 1864, in response to a raid by Jubal Early and his Confederate army of 15,000 on Washington, D.C., and especially his defeat of Lew Wallace at the Battle of Monocacy Junction. The new Army of the Shenandoah was composed of the Union VI Corps (commanded by Horatio G. Wright), XIX Corps (William H. Emory), and George Crook's Army of West Virginia (VIII Corps). It was placed under Sheridan's command with orders to repel Early, deal with Confederate guerillas, and press on into the Shenandoah Valley in Virginia. Early, ever the cunning strategist, kept his force moving so as not to be
