- Cooper organized the 1st Choctaw/Chickasaw Mounted Rifles, and led a brigade against Opothleyahola at Round Mountain, Chusto-Talasah, and Chustenahlah. He then fought in Arkansas and Missouri at Pea Ridge, Newtonia, and Honey Springs before being promoted brigadier and placed in command of all Indian cavalry west of the Mississippi.
- Taylor I don't know much about, I remember finding him in an order of battle;
- Rogers died at Corinth, there's a lot of articles about his charge

- General McNair organized the Fourth Arkansas Infantry, and later led the brigade until Chattanooga, I believe, after which the brigade went to D. H. Reynolds and General McNair was transferred to the Trans-Mississippi to command the Consolidated Arkansas brigade.
- General Greer organized the 3rd Texas Cavalry (or South Kansas/Texas Cavalry) and fought at Pea Ridge, where he became embroiled in a command dispute with General Albert Pike after the deaths of Ben McCulloch and James McIntosh. He later was transferred back to Texas to command the Texas Reserve Corps, until he was relieved by Jerome B. Robertson
- Colonel Harrison commanded the famed 8th Texas Cavalry after the deaths of Colonels Terry and Lubbock. He was promoted to brigadier at war's end, and was wounded a month before Johnston's surrender.
