Below is a map of Louisiana I pulled from the CD version of "Confederate Military HIstory". The map, as well as other state maps of the Trans-Mississippi, can be found in the Atlas of the Official Records of the War of the Rebellion. If this is similar to what you are hunting you should be able to find this book at one of your local libraries or at least at a University library near you. It is a large book and you would probably need to have them copy it, if they are capable, or maybe bring a very good digital camera with you.

I can pull the other state maps for you (I think) but it may be next week as I will be offline for a few days starting tomoroow and I have a class to teach tonight.
