Historians have been looking at the death estimates from the Civil War and there is a general agreement that they are far too low. A study was done recently that compared the men to women ratio from the 1860 and 1870 censuses, and they discovered that the actual number is likely somewhere between 950,000 and 1,200,000.
Yes I have seen that debate. The South was so devastated that records are lost and incomplete. We will never really know. BUT we can be sure that a 6 to 7 million KIA list is not unreasonable if a mass rebellion against Washington happens. But I don’t think it will as people have a lot to lose. Cable TV, NBA games, NFL, pretty good lifestyle. But if the economy collapses and food shortages take place all bets are off.
