You may want to read the books:
"War at Every Door: Partisan Politics & Guerrilla Violenace in East Tennessee 1806-1869" by Noel C. Fisher, U of NC Press, 1997.
"Mountain Rebels: East Tennessee Confederates and the Civil War, 1860-1870" by W. Todd Groce, UT Press, 1999.
"Divided Loyalties" barely meets my standards for scholarly work on the subject. It it Knoxville centric and has several inaccuracies in it.
I hope this helps.
