The Kentucky 3rd Cavalry Regiment (Duke's Brigade was formed during the late fall of 1864 with men who had served under John Hunt Morgan. After skirmishing in Tennessee it was chosen as escort to President Davis. It surrendered at Washington, Georgia, on May 10, 1865.

The men of Battery or Hewitt's Battery were recruited by Capt. Hewitt for infantry service, but as an artillery company was needed, it was drilled for that service, and was mustered as such by Gen. Thomas October 8, 1861. At that early period of the war it was under Gen. Thomas, and was used in the parts of the state about Somerset, Columbia and toward Cumberland river. Technically this unit was the Kentucky 3rd Artillery Regiment, Company B, but it was generally known as an independent Battery. The career of this battery was most useful and honorable, beginning with Gen. Thomas, when he was contending with Zollicoffer's forces in Eastern Kentucky, it faithfully obeyed every order and bravely discharged every duty it was called upon to perform for full three years of active field service. While the Battery was at Murfeesboro, the place was attacked by Forrest, and a part of the Federal forces, was captured. At this time Battery B lost two guns. The battery fired four hundred and ninety three rounds.

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.
