Sherman had pledged to make Georgia howl as he marched to the sea. The scattered resistance the south put up was only a token as Sherman Marched across Georgia. He did this to the trains to make it impossible for the south to use them again if they should reoccupy the area. He took livestock to feed his men and also keep them from the enemy.. . Scorched earth is more of a policy of an Army that is retreating, Sherman was not retreating. He was advancing. The south did not want to ruin the railroads, but Sherman did it for them.
