[30] Major-General Van Dorn. The Twelfth, Col. Henry Hughes; Sixteenth, Col. Carnot Posey; Nineteenth, Col. H. C. Mott; and the Twenty-first, Col. Benjamin G. Humphreys, were to compose the Fifth brigade of the same division, under Richard Griffith, promoted to brigadier-general.

The last brigade was actually formed with the substitution of the Thirteenth for the Twelfth, and at the beginning of 1862 was stationed under D. H. Hill at Leesburg; but the other brigade was for some reason not formed, and the regiments remained separated—the Twelfth in Rodes' brigade, the Nineteenth in Wilcox's, the Sixteenth in Trimble's, the Eleventh in Whiting's. The Second was transferred from the latter brigade to General Rains' division, at Yorktown.

Gresham's Mississippi battery meanwhile was attached to Ransom's brigade in North Carolina. The Jeff Davis Legion, composed of three Mississippi cavalry companies, two Alabama and one Georgia, was assigned to Stuart's cavalry brigade. The Twentieth Mississippi, Col. D. R. Russell, had been attached to the command of General Floyd, in western Virginia, and shared the frightful sufferings of the forces under Gen. R. E. Lee at Sewell Mountain during the autumn, but on account of the retreat of Rosecrans from their front did not engage in battle.
