I find no W. Brand's in Alabama Confederate units, nor any Brand in the 5th Alabama Cavalry.
5th Regiment, Alabama Cavalry
5th Cavalry Regiment, organized at Tuscumbia, Alabama, in December, 1862, recruited its men in Morgan, Lawrence, Fayette, Franklin, Lauderdale, Tuscaloosa, and Marion counties. It was placed in General W.T. Martin's, then Roddey's Brigade, and took an active part in the operations in East Tennessee and Northern Alabama. Later the unit transferred to the Department of Alabama, Mississippi, and East Louisiana and fought at Brice's Cross Roads, Pond Spring, and Selma, where many were captured. The small force that remained surrendered at Danville, Alabama, on May 6, 1865. Its field officers were Colonel Josiah Patterson, Lieutenant Colonel James M. Warren, and Major R.F. Gibson.

This regiment wee organized at Tuscumbia in December, 1862 and
was sent into middle Tennessee, where it began a brilliant
career by skirmishes at Chapel HilL.
After serving a short time in Martin's brigade, it was
transferred to Roddey's, and served continuously during the
war. It was in Florida for a short time during the fall of
1863, but much of its service was in northern Alabama and
vicinity.
It captured a wagon-train at Hamburg, 60 prisoners and a train
at Hunt's Mill, and 130 prisoners at Madison Station. It
blocked the railroad in Rosecrans' rear, fought General Long
at Moulton, stampeded a regiment at Oak hill, and accompanied
General Forrest on his Pulaski raid.
It skirmished with Steedman as he marched into the Tennessee
valley, and fought Wilson all the way from Montevallo to
Selma, where it took part in the defense of the city.
The greater part of the regiment surrendered at Selma, the
remainder at Danville, Morgan county.
Col. Josiah Patterson creditably commanded the regiment till
the close of the war.
