 Cocke's Regiment was designated as the 6th Trans-Mississippi Rifle Regiment; and, the officers and men of Cocke's Regiment quickly began referring to the regiment as the 6th Arkansas.This redesignation causes more confusion because this designation had already been given to Lyon's-Hawthorn's-Smith's elite 6th Arkansas Infantry Regiment in the Army of Tennessee, on the east side of the Mississippi River.This incorrect association with the other 6th Arkansas Infantry is further reinforced by the fact that A. T. Hawthorn commanded the original "6th Arkansas Infantry Regiment" for a time, and later commanded the "other" 6th Arkansas, the 6th Trans-Mississippi (39th Arkansas Infantry Regiment).
