Bama:
There are a few misconceptions in your statement ...
"Why add atrocity to victory, if you know you are the victor in this struggle? Atrocity couldn't hasten military victory, as per your thoughts on the war being won already. Do you condone brutality, as a civilized man?"
In full-scale war, burning the foe's symbols was not considered an atrocity. I might agree with "wanton destruction," but "atrocity" is not an accurate description.
For "a war already won." We can see that it was already won. I suspect the
CSA saw that it was already won. But wars are not won until the other side quits and sues for peace.
What you suggest sounds like, "We've whupped 'em. Let's let them catch their breath so we can resume fighting a gentleman's war." Wars don't work that way. When you've got the heat up, they're running, and the end is in sight, that's the time to crank up the heat -- when they're getting to look on quitting as a good idea.
Atrocity? I see monuments to criminal folly.
Respectfully,
Ole
