No, hardly, and for examples, consider German Generals Rommel and Von Manstein -- both admired by their enemies and never accused of war crimes.
In the US Civil War, the same can be said of Generals Lee & Jackson, amongst others.
The charge of "war crimes" requires particularly heinous actions, of which our Civil War was remarkably free.
Yes, there were some "war crimes" committed, but in comparison to other wars at other times, remarkably few, imho.
Zackly. Compare ANY other great civil war to ours and we had a LOT fewer atrocities.
At the worst atrocity, the Lawrence Raid, the southern irregulars didn’t rape the women. In fact, they’d generally tip their hats to the ladies before throwing their husbands and sons into the burning building.
Not pleasant, but a lot less awful than any other civil war.
Comedy?
