I think part of the problem is that the 7 militia Tennessee starts with is not nearly enough to garrison their cities. By my count, Tennessee has more towns/cities than any other Confederate state (18, vs. 17 for Virginia & Georgia), while four states (Alabama, Mississippi, North Carolina, & Virginia) can recruit more militia than Tennessee. The issue gets noticed because Tennessee is in the front lines & susceptible to Union cavalry raids, but has much fewer militia available (in relation to the number of cities to defend) than either Arkansas or Virginia.
FYI, going through the April 1861 CSA events, I come up with the following militia pools for each state, in comparison to the number of towns/cities (I excluded pre-existing forts):
Code: Select all
Pool Cities
Alabama 10 13
Arkansas 7 6
Florida 4 11
Georgia 6 17
Louisiana 7 12
Mississippi 9 9
N. Carolina 8 15
S. Carolina 5 10
Tennessee 7 18
Texas 4 8
Virginia 12 17
