The Consolidated Regiment remained at White Sulphur Springs until late July 1863 training and as part of the lower Arkansas River Valley defenses. Initially assigned in an unattached status to Frost's Brigade in southeastern Arkansas in May and June 1863. Daniel Frost took command of the "defenses of the Lower Arkansas River" with the departure of Major General John Walkers Division to Louisiana in late April 1863. Colonel John Clark assumed command of Frost's old brigade and Fort Pleasant. The 19th/24th Consolidated moved with Colonel John Clark's Missouri Brigade of Frost's Missouri Division from Fort Pleasant to the defenses of Little Rock in August 1863. On August 15, 1865, the unit was marched through Little Rock, and entrenched on the north side of the Arkansas River. The unit retreated from Little Rock without becoming engaged in the Battle of Bayou Fourche.
