According to the organization chart dated July 3, 1862, Dept. of East Tennessee, this regiment belonged to the First Brigade of Henry Heth's Division, Brig. Gen. Danville Leadbetter. During the previous three months General Ledbetter had been directing the defense of Chattanooga as post commander. Regiments assigned included the 43rd Alabama Regiment, Col. Archibald Gracie, Jr.; 43rd Tennessee Regiment, Col. James W. Gillespie; 34th (59th) Georgia Regiment, Col. J. A. W. Johnson; and 56th Georgia Regiment, Col. Elihu P. Watkins. Capt. George A. Dure's Jackson Artillery from Georgia also belonged to the brigade, but remained at Chattanooga when the rest of the brigade left town.

RICHMOND, VA., October 19 1862. General SAMUEL JONES, Knoxville, Teun.: Send orders to Brigadier-General Leadbetter, wherever he may be, to repair immediately to Mobile, and report as chief engineer for the troops and works in that harbor. The case is urgent and requires dispatch. S. COOPER, Adjutant and Inspector General.

At the end of October Kirby Smith's command reorganized, the brigades of Seth M. Barton, W. G. M. Davis and James E. Rains retaining their prior composition with almost no change. However, a new brigade was created for Col. Archilbald Gracie to include his 43rd Alabama and several new regiments. Brigades led by Col. A. W. Reynolds, Brig. Gen. Thomas H. Taylor and Brig. Gen. Edward D. Tracy were completely reorganized. Tracy replaced Leadbetter, receiving two regiments each from Taylor and Reynolds. Reynolds kept the 39th North Carolina and the 3rd Maryland Battery, to which were added one of Leadbetter's regiments and three from Taylor's old brigade. Taylor got a battery from Rains (the Cherokee Artillery, Capt. Max Van den Corput), two regiments each from Leadbetter and Reynolds, plus a regiment just brought up fom Georgia.

It would be interesting to learn the reasoning behomd these extensive changes.
