There were two companies designated as Co. I in Burbridge's 4th Missouri Cavalry. (old) Co. I, the one your ancestor served in, was actually an Arkansas company, Capt. Lorenzo Dow Bryant's mounted company, which was recruited in Fulton County, Arkansas, but included some Missourians from Howell and Oregon counties. The company was organized in December 1862 and was attached to the 4th Missouri Cavalry as (old) Co. I until April 1863, when it was detached and assigned to the 5th Arkansas Cavalry as Company G.

The 5th Arkansas Cavalry went by a variety of unofficial names during its existence. When Col. Robert Crittenden Newton was in command, it went by its official title of 5th Arkansas Cavalry. When he was succeeded by Col. Thomas Jefferson Morgan, it went by the designation 8th Arkansas Cavalry; but it was also known on occasion as the 2nd Arkansas Cavalry. The Compiled Service Records are filed under the designation 8th Arkansas Cavalry.

Note: This regiment should not be confused with a later regiment commanded by Col. Robert Crittenden Newton, which was a regiment of Arkansas State Troops usually referred to as the 10th Arkansas Cavalry (not to be confused with Crawford's or Witt's regiments, also referred to as the 10th Arkansas Cavalry).

Most of the members of the 5th/8th Arkansas Cavalry who were captured in the battle for Little Rock in September 1863 were sent to Camp Morton, near Indianapolis, Indiana. A few died in prison, a few joined the U.S. Army frontier service, but most were exchanged in March 1864. Many of these men, such as your ancestor, were back in Arkansas in time to be paroled at Jacksonport, Arkansas, on June 5, 1865, at the end of the war.
