Bryan-Thanks for the additional information on the 3rd Cavalry to "add to my notes." If you ever get around to finishing the organization of your notes, I should send you my "piles" to deciper and organize. Whew! What a mess. I'm trying to transfer some of the information to the computer, but now my dang machine is suffering from an unkown illness--most likely an "operator allergy."
Here is a "rough" paraphrase of one of my more difficult to read notes that may pertain to the numbering issue.
You may know something about the officers named in the two battalions. I made a quick look up and found the confusing information that W. D. Barnett was the LtCol of the 1st Florida Reserves. And, of course, McNeil went on to become the Colonel of the 30th Arkansas infantry.
Then again, maybe these references have nothing to do with the 2nd or 3rd cavalry regiments.
A & IG writes to Bragg regarding the June 22, 1862 cavalry organization. Says the new Arkansas cavalry regiment has no numerical designation, and that another Arkansas cavalry regiment is forming from W. D. Barnett's bn [2nd Ark bn] and A. J. McNeil's bn. Says his office has roles on the first unit but not the second.
And here is yet another order regarding the 3rd cavalry.
