There are few records of the 12th Arkansas after the fall of Port Hudson. After being paroled, the enlisted personnel of the 12th Arkansas made their way to parole camps near Camden in south Arkansas and were eventually declared exchanged. They served as mounted infantry as a part of Colonel Thomas Pleasant Dockery's Brigade during the Camden Expedition in the Spring of 1864. As part of Dockery's Brigade, remnants of the regiment saw action at the Battles of Prairie D'Ane, Marks' Mills, and Jenkins Ferry.
