hot military history take 2;
The CSA lost because being agrarian meant they didn't have logistical advantages and counted on Britain and France outmatching Union production. And of course THAT relates to fighting for slavery. Without an Emancipation Proclamation, might Britain have joined the side that offered them cheap cotton?
So this hits all sorts of southern cultural buttons about being rural (when the future of the south was bound to be more urbanized), independent self made men, etc etc.
