Chambersburg was an anomaly that is why it is always "remembered". What are your OTHER examples? For every example you come up with anyone could counter with 100 Yankee examples. So your liberal tactics aren't going to work.
Of course, since most of the war was fought in Confederate states.
But not all, and whenever Confederate forces had the chance to invade Union states or territories, they did, including the long list of states I mentioned in post #74 above.
In every case, Confederate forces "lived off the land", taking what they needed and often leaving trails of destruction behind them.
Indeed, for many of these operations (i.e., in Ohio, Indiana & Kentucky), their purpose was to gather up as many Union supplies as possible to equip Confederate forces.
If you are truly interested in details, then simply google the words "Civil War" followed by the particular state or territory, and it will explain all the military operations there.
By the way, in post #74, I did mention two specific examples -- Chambersburg and Lawrence Kansas.
So far as I know, they are the worst, but others suffered to lesser degrees.
