In fact, Confederate forces looted, destroyed and "lived off the land" everywhere they went, especially outside the Confederacy proper.
Sure, some generals like Lee made a show of "paying for" forced "requisitions" with nearly worthless Confederate money, but most just took what they needed and destroyed what they thought useful to the Union.
Despite all that, the Civil War included remarkably few atrocities, I.e. civilians murdered, but more by Confederates (Lawrence Kansas to mention one) than Union troops.
Sorry, I’ve just never read of the systematic, wholesale, wanton destruction perpetrated by the South that I’ve read of with Sherman.
This Chambersburg stuff is small potatoes to Sherman’s antics, akin to saying, “See, here’s a GI who shot a Nazi prisoner, so how can you complain about Auschwitz.”
