This is largely a repost of an item in the Historical Accuracy Mod thread.
I would most like to see some political texture similar to Maryland in Tennessee (and Kentucky). There were profound regional differences that were major influences in the strategy of the Civil War. The South had to maintain troops sitting on East Tennessee and Lincoln was always pressing for an incursion into East Tennessee causing friction with Buell and Rosecrans (due to logistical diffculties) until he was finally able to push Burnside into a moderately risky incursion into Knoxville. Ironically, after for over a year, after the fall of Memphis, the Union controlled the secessionist part of the state and the South controlled the unionist part of the State.
Here's a start of the political texture of Tennessee:
Tennessee Loyalty
--------------------------------------------------------------------------------
East Tennessee loyalty figures need profound adjustment in the vanilla 1861 versions. Tennessee had a referendum on secession after secession had been effectuated and troops sent to Virginia. The 26 East Tenneessee counties voted 2-1 against secession (69%).
"Governor Harris angrily refused to abide such an effort. Believing that Tennesseans now preferred joining the Confederacy to preserving the Union by force, he promoted a renewed effort to depart from the United States. This culminated in another referendum four months after the initial defeat of the convention call. This time Tennessee voters were directly asked if they favored or opposed "separation." The result of this second election, June 6, 1861, approved exiting the Union. A comparison of the February and June returns reveals that there was little change in opinion in either the west or the east. The former remained in tune with secession, although Weakley, Carroll, Henderson, Decatur, and Hardin counties did defeat the proposal and went on to provide significant numbers of recruits for the Union Army. In the east, only five counties (Rhea, Meigs, Polk, Monroe, and Sullivan) favored abandoning the old flag. It was in Middle Tennessee where the greatest shift in opinion occurred. There, twelve counties that opposed a convention call in February, suggesting a reluctance to secede then, approved secession in June. These twelve (Jackson, Overton, Wilson, Smith, Putnam, Williamson, Rutherford, DeKalb, White, Cannon, Bedford, and Coffee) had the balance of power as they accounted for the different outcomes of the two elections.6

(There is also info in this paper about different levels of support in Kentucky and the counties which provided union volunteers and didn't)
Tennessee also provided 31,000 volunteers for the Union army - 3.19% of the population (compared to a high of 12.56% in IL and a low of 8.95% in NJ) and about 100,000 for the Confederacy (I've seen ranges of 100-112K). 44 TN counties voted for secession by more than 2-1. East Tennessee political figures then attempted to seceed from the state and confederate troops basically had to occupy the region.

by Noel C. Fisher - 2001 - History - 264 pages - the Google excerpt contains a map of the election results (county majorities).
The regions which should be effected are 568-69, 592-608. I alter 569 and 592 to 55% loyalty and the rest to 45% to be conservative, but given the atmosphere under which folks were openly voting against secession (no secret ballot yet) 33% Confederate is probably more accurate for most of east Tennessee.
