Long before 1864 Capt Alexander D Brown had been reassigned to Co A, 3rd Missouri Cavalry. As such he served the rest of the war west of the Mississippi. Have no idea who Capt A D Brown in Featherston's Brigade could be. He is not a member of Hawkins Shaprshooters and isn't mentioned elsewhere in the O.R. The O.R. index says, "Brown's (A.D.) Infantry (designation not of record)."
