The Georgia 4th Cavalry Regiment (AveryÕs) was formed with eleven companies in January, 1863, using Avery's 23rd Georgia Cavalry Battalion as its nucleus. It served for a time with the Conscript Department in Tennessee, then was assigned to J.J. Morrison's, C.C. Crews', and Iverson's Brigade. The regiment participated in the Chickamauga, Knoxville, and Atlanta Campaigns, skirmished in Northern Georgia and East Tennessee, and took part in the defense of Savannah. In January, 1865, the unit was reorganized and called the 12th Cavalry. It went on to fight in the Carolinas and surrendered with the Army of Tennessee. Research of this unit is complicated by the fact that there was another 4th Cavalry (ClinchÕs). No roster of the 23rd Cavalry Battalion or the 4th Cavalry (AveryÕs) has been found. The records are all filed in the state archive microfilm as the GA 12th Cavalry Regiment.

In June 1864, General Ulysses Grant ordered his cavalry commander, Philip Sheridan, to conduct a raid to destroy the Virginia Central Railroad between Charlottesville and Richmond. Sheridan fell short of his objective when he was defeated by General Wade Hampton's cavalry in a two-day battle at Trevilian Station. The first day's fighting saw dismounted Yankees and Rebels engaged at close range in dense forest. By day's end, Hampton had withdrawn to the west. Advancing the next morning, Sheridan found Hampton dug in behind hastily built fortifications and launched seven dismounted assaults, each repulsed with heavy casualties. As darkness fell, the Confederates counterattacked, driving the Union forces from the field. Sheridan began his withdrawal that night, an ordeal for his men, the Union wounded and Confederate prisoners brought off the field and the hundreds of starved and exhausted horses that marked his retreat, killed to prevent their falling into Confederate hands.

The North Carolina 10th Artillery Battalion [also called 2nd Battalion Heavy Artillery] was organized during the spring of 1862 at Wilmington, North Carolina, with three companies, later increased to four. The unit served at Fort Caswell and Wilmington, then in December, 1864, was active in the defense of Savannah. Later it saw action in the North Carolina Campaign as infantry and surrendered with the Army of Tennessee. Major Wilton L. Young was in command.
