On April 15, 1865, Lieutenant Colonel Cleveland, with that portion of his regiment which was then at Nashville, was ordered to proceed to Carthage, take post there, and report by letter to Colonel Gilfillan, commanding 4th Sub-district of Middle Tennessee. On April 30, the 8th Tennessee Mounted Infantry (four companies) was reported in Colonel James Gilfillan’s 4th Sub-district.
On June 22, 1865, Company “E”, 8th Tennessee Mounted Infantry, was relieved from duty at Clifton, and ordered to proceed to Savannah, Tennessee, and establish headquarters at that place.
These were the only mentions of the regiment found in the Official Records. Adjutant General J. P. Brownlow, State of Tennessee, stated the rolls of the regiment were very incomplete, and that his office was in session of the rolls of only the first five companies and that they were defective. There seem to have never been more than five companies.
