An aside, but the currently much-discussed and cussed
posse comitatus act came about as a direct result of the inability of our blue-clad northern visitors to behave themselves in polite company in the immediate aftermath of the recent unpleasantness. How the hell this act ever became warped and twisted to claim that the military can't be used to protect our borders is beyond me.
BTW, we were using the ploy mentioned in this article a year earlier at Vicksburg. Yankee prisoners were locked in the upper floor of the courthouse to deter the Union navy from shelling it. This act probably saved that marvelous building from destruction, leaving it as one of the few remaining antebellum courthouses in the South. If you ever go to Vicksburg it is a must-see.
