Receiving authority to assemble a mounted regiment, Col. A. A. Hunt recruited under provisions of the Partisan Ranger Act. By May 14, 1862, he had organized six companies which soon went into camp near Atlanta, Ga. Officers and men received equipment and drilled at Camp McDonald from May 27th through June 21st, 1862.

During the summer of 1862, the command was known as the 1st Georgia Partisan Ranger Regiment.

Field officers were A. A. Hunt, Colonel; F. M. Nix, Lieutenant Colonel; S. J. Winn, Major. However, only six companies were assigned to Hunt's command:

Co. “A” from Euharlee [Polk County], Ga., Capt. Thomas F. Jones.
Co. “B” from Covington [Newton County], Ga., Capt. William Bailey.
Co. “C” from Monticello [Jasper County], Ga., Capt. A. J. Walters.
Co. “D” from Dahlonega [Lumpkin County], Ga., Capt. David A. Camp.
Co. “E” from Jefferson [Jackson County], Ga., Capt. William L. Marler.
Co. “F” from Newnan [Coweta County], Ga., Capt. John D. Sims.

Ordered to Knoxville, Tenn., the battalion was assigned to the command of Col. John Hunt Morgan. This officer was assembling a force for a raid into Kentucky, which left Knoxville on July 4th. Reports of Morgan's raid appears in the Official Records.

Shortly after Morgan’s men returned to Tennessee, the Georgia battalion went into camp near Knoxville, Tenn. Officers and men were allowed at least three weeks at “Camp Hunt” for rest and refit. By Aug. 25, 1862, however, the battalion had been assigned to duty at Clinton, Tenn., where it remained until Sept. 8th. At that time it was pressed forward to Jacksboro, Tenn. On that date Brig. Gen. James P. McCown directed the various companies of the battalion to secure the passes at Big Creek and Rogers’ Gap, vital for maintaining communications with the Confederate army in Kentucky.

Here's a reference from the Official Records describing assignments and duties of this command.

O.R.-- SERIES I--VOLUME XVI/2, p. 852.

HEADQUARTERS DEPARTMENT OF EAST TENNESSEE, Knoxville, Tenn., September 19, 1862.

Maj. [SAML. J.] WINN, Commanding Battalion:

The major-general commanding this department directs that you move your command at once to Big Creek Gap and cross the mountain to Pine Mountain, and remove the obstructions placed in the road by the enemy. You will move on via Boston to Barboursville, Ky., and make your headquarters there until further orders. You will keep him at all times informed in regard to your operations by couriers. If on the route you meet an enemy you will attack him, unless his force is too large to warrant success. You will subsist your command (man and horse) off of the country, giving duplicate receipts for all subsistence purchased from citizens loyal to the existing Government, and persons suspected must make satisfactory evidence of their good intentions while our forces occupy the State of Kentucky. You will be particular to prevent any depredations being committed by any of your troops, and any one so offending must be punished, as no excesses will be allowed by any troops of this command. All property captured from persons in arms or from the enemy will be promptly reported to these headquarters.

H. S. BRADFORD, Assistant Adjutant-General.

I don't believe the horse's name had anything to do with the battalion's assignments in 1862 or 1863. As mentioned earlier, it was not assigned to north or central Virginia until May 1864.
