Newton did command the 5th, but that was before he was given command of this new regiment of state troops. In an earlier post Bryan indicated "Note: This regiment should not be confused with a later regiment commanded by Col. Robert Crittenden Newton, which was a regiment of Arkansas State Troops usually referred to as the 10th Arkansas Cavalry" I have check the Grebes site and the 10th Cavalry listed there appears to be Witt's Regiment, which I do not think is this unit. I think this unit under Newton participated in Operations concerned with the Camden Expedition.
