Sherman's aim was to destroy anything of use to the Confederate Armies. I don't see where he destroyed anything that would become US property. His path of destruction certainly affected a large part of the future economy of the states he went through.I ask this as a result of another thread.
The destruction of property and land during Sherman's assault through the "seat of secession" if the answer to the question is yes; was destruction of what would be United States property and part of the future economy of the country.
If the answer is no then I would presume all bets are off and his intention to make the destruction complete was to a degree understandable.
Northern industry came out of the war stronger than when it started.
