[Qui is]

To quote my Aunt Clara (from Thomaston, GA):

“The War between the states (Civil War) didn’t have a damn thing to do with slavery. It was about the price of a bail of cotton.

.....lived for almost a half-century in various parts of the Commonwealth of Virginia....it was “The war of Northern Agression” to quite a few old-timers.....or “The recent unpleasantness....” to others....

I think the units of cotton are referred as “bales” not “bails”
Bail is money paid for the conditional release of a defendant with the promise to appear in court when required
