The Trustees for Historic Magnolia Cemetery and the Foundation for Historical Louisiana have just released a very nice driving/walking tour brochure related to the Civil War in Baton Rouge, with particular emphasis on the Battle of Baton Rouge.
Here is a link to the pdf of the brochure at the CivilWarAlbum.com webpage for Baton Rouge: http://www.civilwaralbum.com/louisiana/batonrouge.htm
