This may be beyond the information that you have on this regiment, but I am trying to sort out some consolidations that occured in 1864. I have a couple of references to the 30th being consolidated with the 32nd Arkansas and some references to the 30th being consolidated with Hardy's Regiment. I supose either is possible since it looks like the 30th was pretty small after the Helena campaign, but I don't have real documentation on either consolidation. The 30th doesn't really appear in any of the Red River/Camden Expedition information but Rogan pops up with a mounted command during Price's Raid and Rogan and the 30th are listed in Gause/Roane' Brigade in December 1864.
