An article titled "The March to the Sea" by Steven E. Woodworth. It was in a magazine called "1864" which was a special edition from the publishers of America's Civil War, Civil War Times, and Military History magazines. It was on sale last month, and is available for purchase online here, but unfortunately they haven't posted any of the articles online.
NS says: "Circumstances point to the conclusion that actual plundering of nonedible property was minimal during the march to the sea, and possibly less than what confederates destroyed in Pennsylvania."
Could you source that quote?
NS: "but unfortunately they haven't posted any of the articles online."
So, until someone finds it, I would trust General Sherman himself.
In his memoirs Sherman boasted that his army destroyed more than $100 million in private property and carried home $20 million more during his "march to the sea."
