When the South briefly invaded the North they did so honorably paying, even in basically worthless money, for what they took.
I have ancestors that were on both sides. However after researching and reading the daily correspondence of officers from both sides of Sherman’s March it is pretty clear what occurred. The two items most covered up in history texts were the considerable number,of rapes of Southern women by Union soldiers and the over 3,000 for women slaves who followed the army providing sexual favors to the troops. Most of the officers thought this was an abominable practice but Sherman himself ordered no action to be taken to stop the practice.
Considering what Sherman later visited on the native Americans and it is clear he was a subhuman being who had little respect for his adversaries.
Not completely worthless. At the time of Lee's invasion of PA in 1863 the exchange rate was $0.25 CSD to $1.00 USD.
"Worthless" being the operative word here.
In fact, there were numerous Confederate invasions of Union states & territories -- only two of which were under Lee's command (Antietam & Gettysburg).
In every case, Confederates "lived off the land", took what they needed, destroyed anything of military value they could not take (i.e., railroad bridges), and sometimes destroyed civilian property (i.e., Chambersburg PA).
Regardless of false accusations, both Union & Confederate armies treated civilians reasonably, killing very few and nearly all of those accidentally.
But the Confederate Army always did something for which there is no Union equivalent: Confederates kidnapped free Northern blacks, returning them for sale as slaves in the South.
Central_Va: "At the time of Lee's invasion of PA in 1863 the exchange rate was $0.25 CSD to $1.00 USD."
Still basically worthless because: 1) all "sales" were in fact requisitions, forced not voluntary, 2) Prices, such as they were, were set by Confederates, and 3) Confederate money was "fiat money" backed by nothing and subject to rapid inflation.
For example, by the end of 1863 the dollar you say was worth $.25 in July was quoted at $.06.
