Thanks for the email. Your ancestor's story sounds very interesting. In my book, check the reference to Gildrie (endnote #31). It is a good reference for gurrilla activity in the Clarksville area (south of river). There is a recent book out regarding a guerrilla in the area (can't think of the name of the book or author right now). This book might be pertinent. I'll check it out after work today (leaving for work in about 5 min) and get back to you.
