The Georgia 6th Cavalry Battalion State Guards was formed in August 1863 to serve for six months as local defense in the northwest section of the state. The battalion was comprised of horse soldiers from Chattooga and Walker counties. The only verified engagement with the enemy is noted on January 22, 1864, at the "Battle of Subligna" in Chattooga County. As Sherman threatened in the spring of 1864, most of these men probably joined in with Wheeler's or Forrest's troops for the Atlanta and Carolinas campaign, but records are sparse.

The Tennessee 18th Cavalry Regiment was also called the 19th Regiment. It was organized in May, 1864, by consolidating six companies of Newsom's Tennessee Cavalry Regiment and four companies of Forrest's Alabama Cavalry Regiment, The unit was assigned to T.H. Bell's Brigade in the Department of Alabama, Mississippi, and East Louisiana. Its members were recruited in Hardeman, Madison, Henderson, and McNairy counties.

The Mississippi 4th Infantry Regiment was organized at Grenada as the Fourth Regiment, Second Brigade, Army of Mississippi, and enlisted for twelve months. The Fourth was among the troops posted at Fort Henry on the Tennessee River, under General Lloyd Tilghman. The troops were transferred to Fort Donelson and there captured. Following exchange they were then surrendered at Vicksburg and continued throughout the remainder of the war in the Atlanta Campaign, Franklin, and Nashville, ending the war in the defense of Mobile.

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.

The Louisiana 12th Infantry Regiment completed its organization at Camp Moore, Louisiana, in August, 1861. Its companies were from the parishes of Caldwell, Claiborne, Vermilion, Cameron, Calcasieu, Jackson, Ouachita, Bossier, and Iberia. Sent to Missouri, the unit was captured at Island No. 10 in April, 1862. After being exchanged, it was assigned to Rust's, Buford's, T.M. Scott's, and Lowry's Brigade. It fought at Champion's Hill and Jackson before participating in the campaigns of the Army of Tennessee from Resaca to Bentonville. In July, 1862, the unit contained 41 officers and 546 men, reported 11 killed, 57 wounded, and 5 missing out of the 318 engaged at Peach Tree Creek, lost many during Hood's Tennessee Campaign, and surrendered with only a remnant on April 26, 1865. Its commanders were Colonel Thomas M. Scott; Lieutenant Colonels James A. Boyd, Wade H. Hough, Noel L. Nelson, and Thomas C. Standifer; and Majors John C. Knott and Henry V. McCain.
