East Tennessee was not a solid block of Union supporters. Jonesborough was heavily Confederate and sentiment often varied from hollow to hollow.
Huh, didn’t know that, but in any case, is that all that different from the Confederacy as a whole? There were many in the south who opposed secession or were outright unionists. In some areas, such as northern Alabama, or in border regions, they were comparable in numbers to the pro-secessionists.
