I believe a couple of years ago when Greg Biggs was leading a tour of the Civil War sites in the Clarksville area for a few of us we visited the site of this battle on our way out to Fort Donelson. He posts here on a regular basis so you should be able to send him a note of he doesn't see this in the next day or so. Or you might can contact him at the Clarksville Civil War roundtable site at http://clarksvillecivilwar.wordpress.com/
