The un numbered regiments listed on the Order Of Battle I have are:
Gordon's Arkansas Cavalry: Col Anderson Gordon Which I belive is the Gordon's 4th/9th Arkansas Cav
Hill's Arkansas Cavalry Battalion: Col John F. Hill Which I believe is the 7th Arkansas Cav
Monroe's Arkansas Cavalry: Col James C. Monroe Which I belive is Monroe's 1st/6th/4th Arkansas Cav
Morgan's Arkansas Cavalry: Col Thomas J. Morgan Which I belive is Morgan's 5th/2nd Arkansas Cav
Dobbin's Arkansas Cavalry: Col Archibald S. Dobbin Which I belive is Dobbin's 1st Arkansas Cav
McGhee's Arkansas Cavalry: Col James H. McGee (w Oct. 23), Ltc Jesse S. Grider Which I believe is the 29th Arkansas Cavalry Regiment

Crawford's Arkansas Cavalry: Col William A. Crawford Which I believe is Crawfords 1st/10th Arkansas Cav

That seems to leave the following unit for which I have no numerical designation:

Carlton's Arkansas Cavalry: Col Charles H. Carlton

Is anyone aware of numerical designations for any of these units?
