Before Katrina, I had a book: Encyclopedia of Forts, Post, Named Camps and Other Military Installations in Louisiana, 1700-1981, by Powell A. Casey, it listed every known military site in the state. I tried to replace it, but $180.00, was the lowest price I could find in used condition. If you live in Louisiana, you may find a copy in a library, if you want that type of information. Also check out this site: 18th History: the Camps, Forts, Etc.
