My mom (RIP) was a boomer born and raised in Georgia. In our house, we were taught that General Sherman was in hell right alongside Napoleon and Hitler.
If he is, it’s for his handling of the Native Americans and bison and not for how he prosecuted the March to the Sea. The Confederacy was a boil that needed popping.
My general thought on the March is that glorifying a series of war crimes and mass civilian death is never a good thing, and it wasn’t the wannabe aristocratic slave owners that suffered the most from it.
But war is hell, which is why you should always try to avoid starting one, especially for a contemptible cause.
The March should be filed under the same general heading as the WW2 bombing campaign, it’s one thing to view it as a necessary evil but it’s another thing to revel in it.
