Recruiting for this regiment was begun in October, 1863, and two companies had been mustered into service by the end of 1863; other companies were added during 1864, the last one on November 30, 1864. Abraham E. Garrett was promoted from major to lieutenant colonel on March 18, 1864. The companies were organized at Nashville and at Carthage, and did duty in the District of Middle Tennessee, Department of the Cumberland, until April, 1865, when the regiment was assigned to the 1st Brigade, 1st Subdistrict, District of Middle Tennessee. The first mention of the organization in the Official Records was in the account of an expedition from Gallatin to the Cumberland Mountain area January 28-February 8, 1864. A battalion of Tennessee troops under Major Garrett was a part of the force which moved from Gallatin to Carthage, to Flynn’s Lick, Gainesboro and Livingston, in an attempt to clear the country of Confederate marauders under Colonels 0. P. Hamilton and John M. Hughs.
The next mention was on September 3, 1864, during Major General Joseph Wheeler’s raid into Tennessee, when Colonel William B. Stokes, Commanding Post of Carthage, reported that the troops from Granville, Tennessee, Companies “B”, “C”, “D”, “F”, and “F” of the 1st Tennessee Mounted Infantry, had fallen back to Carthage. Company “A” seems to have been stationed at Gallatin, for on October 10, 1864 Captain Cleveland and 40 men from the 1st Tennessee Mounted Infantry were sent from Gallatin to South Tunnel to protect the tunnel from Confederate guerrillas.
On March 11, 1865, the 1st Tennessee Mounted Infantry at Carthage was ordered to report by letter to Major General L. H. Rousseau, Commanding District of Tennessee, for duty on the line of the Nashville and Chattanooga Railroad. On April 18, 1865, Major McKee and the regiment were ordered to Murfreesboro, to report to Brigadier Gener-al H.P. Van Cleve, Commanding Post at Murfreesboro.
On April 30, 1865, the 1st Tennessee Mounted Infantry (five companies), Major McKee, was assigned to the 1st Brigade, 1st Subdistrict, District of Middle Tennessee. On May 10, 1865, it was proposed that the division should form a separate or movable division in the District of the Etowah, commanded by Major General J. B. Steedman, but no record of transfer to the District of the Etowah was found.
On June 26, 1865, an order was issued directing the detachment of the 1st Tennessee Mounted Infantry, at Murfreesboro, to proceed to Nashville to be mustered out of service. These were evidently the five companies under Major McKee which had been sent to Murfreesboro April 18. No record was found as to what had become of the other five companies of the regiment.
Dyer’s Compendium says the regiment was mustered out at Nashville, July 22, 1865.
