 Unfortunately, the Confederate States War Department, the Trans-Mississippi Department, the brigade commanders, and even the regimental commanders often used designations different from the State Military Board's.The State Military Board designated the regiment as "Cocke's Regiment" as 39th in its ledger book.General Thomas C. Hindmand originally decided to designate all of the Arkansas infantry regiments raised in the District of Arkansas during the summer of 1862 as "Trans-Mississippi Rifle Regiments."
