"I assume that to be Lt Col. Danley also, thus he became officer in charge (?) of Upper Arkansas of Western Dept, CSA, until Gen Van Dorn was placed in charge, 15 Jan 1862."

I am not sure that that would necessarily be the case.

As I understand the situation from the aforementioned book that the reason the Borland's command and several other regiemnets were left behind in Arkansas when Hardee went to Kentucky, was that they were not well organized. Thus their being left behind was less than a compliment.

So I don't know that you would place the commander of such a unit in command of other as badly organized units also.
