Your rape and murder charge is pretty thin, though.
Although, what Forrest did at Fort Pillow sure looks like murder to me.
And what Confederate Lieutenant-colonel James A. Keith did to suspected Union sympathizers in the Shelton Laurel Valley of North Carolina was murder too, not to speak of the fact that he tortured women and killed kids.
And then there were the anti-slavery, pro-Union Texans who were massacred on the Nueces River as they were fleeing martial law and forced conscription into a cause they didn't believe in.
Or, we could talk about the 24 unarmed captured Union troops who were executed at Centralia, MO by William T. Anderson and Jesse James.
Or what Quantrill did to Lawrence, KS, "to plunder, and destroy the town in retaliation for Osceola." They massacred pretty much the entire male population of the town, including boys. Or what they perpetrated at Fort Blair.
And that's without even bringing up the thousands of Union prisoners who died under the most horrific conditions at places like Andersonville.
