Hood's Texas Brigade was organized on October 22, 1861, in Richmond, Virginia. It was initially commanded by Brig. Gen. Louis T. Wigfall and composed of the First, Fourth, and Fifth Texas Infantry regiments, the only Texas troops to fight in the Eastern Theater. The First was commanded by Wigfall and Lt. Col. Hugh McLeod, the Fourth by Col. John Bell Hood and Lt. Col. John Marshall, and the Fifth by Col. James J. Archer and Lt. Jerome B. Robertson. On November 20, 1861, the Eighteenth Georgia Infantry, commanded by William T. Wofford, was attached. On June 1, 1862, eight infantry companies from Wade Hampton's South Carolina Legion, commanded by Lt. Colonel Martin W. Gary, were added, and in November 1862 the Third Arkansas Infantry, commanded by Col. Van H. Manning, joined the brigade. Both the Georgia and South Carolina units were transferred out in November 1862, but the Third Arkansas remained until the end of the war.
