Or did it just set the stage for the revenge of reconstruction?
When southern raiders went north and burned the steel mills owned by Thaddeus Stevens (one of the Radical Republicans who advocated and engineered the harsh postbellum treatment which Lincoln opposed), they were careful not to destroy the hovels where his workers lived near the mills.
From the post:
When the War broke out like every other Southern woman, I immediately began work for the soldiers: I organized a sewing society, to cut and make garments for them. I made it a point to try and meet every train that brought soldiers through our town, and, with others, frequently walked from my home, sometimes at two o'clock in the morning, to take food to our men as they passed through. We always greeted them with the wildest enthusiasm, and no thought of defeat ever entered our minds . Whenever the boys were fortunate enough to get home on short furloughs, they were the guests of the town - everybody feted them and nothing was too much to do in their honor.
So the short answer to your question is a resounding, "Yes." The enemy soldiers and their means of support, in this case the spirit of the citizens, must be crushed as effectively and quickly as possible to acheive the most effective resolution of a war - lasting peace. "There has never been a protracted war from which a country has benefited." - Sun Tzu
Reconstruction, sir, is a different topic.
