Or General George Patton or General Tommy Franks? Would you say that of those men? War isn’t a game of cricket. Sherman wanted to end the ability of the treasonous bastards who started the war in the first place to continue fighting it and end the damned war itself and fast.
You have basically espoused the cause of the character Tavington from the movie The Patriot. He was eager to get all those “treasonous b*****ds” to surrender to the Crown by going after their families. Yes, there are rules in civilized warfare. You don’t burn homes, kill civilians at random, or rape women. You can say, “well Sherman was just trying to end the war fast.” But you can look at a lot of things that people like Hitler did in their wars and say the same thing. Doesn’t make it right.
