There are of course the units and detachments that participated in the well known campaigns -- 1st Indian Expedition, Ft Wayne, Honey Springs, Perryville. There are many others though such as the Confederate 2nd Arkansas Mtd Rifles at Chustenahlah, the 19th Arkanasas Infantry at Ft McCulloch, the many TST and CSA Texas units, of course, and the Union units escorting supply trains, scouting from southwest Missouri into Cowskin and Beaties Prairies, the units that pursued Price to the Arkansas River, etc.
