Just to tag on to this thread, an American historian has just come up with a very interesting hypothesis. The accepted number for the deaths caused by The War Between the States has been around 600000. Around 250000 for the South and around 350000 for the North. The main reason for the inexactness of the number is because the statistics for the South have been sketchy and incomplete, especially for the late stages of the war. The population of the US, including slaves in 1860 was around 31M. The South with around 9M including slaves. The South had around 1M men of draft age and the North around 4M. That meant that approximately 25% of the draft age men in the South died. That must have had a huge impact, considering widows and mothers, not to mention the economic impact.
This historian looked at the 1870 census and realised that the number of men in the age group to have fought in the War was a lot less than it should have been. Taking all into account he now says that the number of deaths was probably greater than the 600000 figure, probably about 750000. Since the Confederate records are the most incomplete, the bulk of that additional 150000 or so must have been Southern boys.
To me the 600000 number split 350K and 250K never made much sense because both sides were said to have about twice as many deaths from disease as from battle wounds. The reason that made no sense to me was that the Union must have had better medical care than the Confederates. Everything else they had was better, food , weapons, railroads, clothing, etc. The other factor is that the Union troops, coming from more urban environments must have had a little more immunity to diseases, like flu, pneumonia, measles, etc. which were the big killers in that war. The Southern boys mostly came from rural areas where they were not quite as likely to gain immunity.
Anyway, the startling thing about this study by the historian probably means that the deaths of Southern men in the War must have been much greater than the 250K. Perhaps as much as 100K greater which means that the 25% of the draft age men goes up a lot more than the corresponding number for the North. One does not hear this expressed much but the War set the South back economically for many years. WW2 was the catalyst which finally began to allow the South to start to catch up with the prosperity that the North and western part of out country had been enjoying prior to the Depression. This study makes one realise that the South was probably effected even more than previously understood.
