The 3rd Texas Cavalry Regiment of the new Arizona Brigade was reorganized pursuant of Special Order #81 on February 21, 1863 and placed under the command of Col. Joseph Phillips.
From December 1863 through April 1863, the 2nd, 3rd and 5th Texas Cavalry Regiments were assigned to the the brigade of Brig. Gen. Thomas Green and served in Louisiana.
The 1st Texas Cavalry was placed under the command of Col. Peter Hardeman and was marched by companies to the Warren Supply Depot in Fannin County near the Red River in order to reach troop strength of ten companies of 100 men each. It served in Gen. Samuel B. Maxey's Division of Arkansas and in Brig. Gen. Richard M. Gano's Brigade in Indian Territory. In July 1863, my great grandfather Joshua D. Coffee enlisted in the 1st Texas Cavalry regiment, Hardeman's Arizona Brigade after it arrived in Fannin County.
The 4th Texas Cavalry was raised on the Pecos River by Col. Spruce M. Baird. The regiment took to the field in late 1863 due to the slowness of reorganization. That is because the regiment consisted of draft evaders, deserters, and other riff-raff who drifted into no-man's land between Confederate Texas and Union held New Mexico. No list of engagements fought by the 4th Texas Cavalry have survived. It is known that the first assignment of the 4th Texas Cavalry was against hostile Indians in northwest Texas. In early 1864, the 4th Texas was sent to the Rio Grande near Brownsville. In the fall of 1864, the regiment was sent to Cooke County in north Texas where it was consolidated with Brig. Gen, Thomas F. Drayton's 3rd Cavalry Division. By January 1865, the 4th Texas Cavalry regiment was in a state of mutiny and was nothing more than a disorganized mob.
The Arizona Brigade was a microcosm of the entire Confederate army, and its men displayed both the best and worst qualities of the Confederate fighting man.
