William Loring in the mountains of western Virginia during his father's Western Virginia Campaign. Loring's forces were transferred to the lower Shenandoah Valley and the command of Stonewall Jackson in late 1861 and occupied the town of Romney in early 1862.
Lee was soon after assigned to the command of Maj. Stuart, who was leading the cavalry forces for Joseph E. Johnston's Army of Northern Virginia, in the Peninsula Campaign. After joining Stuart, Rooney Lee's regiment participated in Stuart's first ride-around the Union army, as well as the subsequent Seven Days Battles around Richmond. During this time, Rooney's nearby White House plantation was burned to the ground, and his son Robert died of typhoid fever.
During the Northern Virginia Campaign, Rooney played a leading role in Stuart's well-crafted attack on General John Pope's supply base at Catlett's Station on August 22, 1862, capturing a paymaster's safe full of Yankee greenbacks. [3] His cavalry regiment was assigned to the brigade of Brig. Fitzhugh Lee, his cousin, for the Maryland Campaign.
Following the Battle of South Mountain, Lee was knocked unconscious after a horse fell from under him, and was unable to participate in the Battle of Antietam. [3] Upon his recovery, he temporarily commanded Fitzhugh Lee's cavalry brigade in Stuart's Chambersburg Raid; his conduct earning him promotion to brigadier general.
He then commanded the 3rd Brigade of Stuart's Cavalry Division at the Battles of Fredericksburg mere weeks after the death of his infant daughter. [3] During the Battle of Chancellorsville the following year, Lee was detached from Stuart's cavalry to defend against Stoneman's 1863 Raid. At the beginning of the Gettysburg Campaign, Lee was shot in the thigh during combat at Brandy Station. He spent the next two weeks recovering at Hickory Hill, Virginia, before being captured by Union forces. In April 1864, Lee was promoted to major general and commanded a division in the Cavalry Corps during the battles of The Wilderness; Todd's Tavern; Spotsylvania Court House; and North Anna in the Overland Campaign. With the death of Jeb Stuart, Rooney Lee's role increased.Lee's cavalry division patrolled the extreme right of the Confederate lines during the Siege of Petersburg, defending against the Wilson-Kautz Raid at Staunton River Bridge, Sappony Church and First Ream's Station. His division was then sent north to briefly aid in the defense of Richmond at the Second Battle of Deep Bottom, before supporting General Wade Hampton III's Beefsteak Raid, and then returning to Petersburg for the Battle of Boydton Plank Road. By last year of the war, Rooney Lee had risen to second-in-command of the Confederate cavalry in Virginia; General Hampton having been transferred to South Carolina to raise troops, and Lee's cousin, Fitzhugh, promoted to overall command.
Lee's cavalry division screened the Confederate evacuation of Petersburg, notably at the Battle of Namozine Church during the Appomattox Campaign. He surrendered along with his father at Appomattox Court House with only 300 officers and men, one-tenth the size of the command during the Petersburg Campaign.
