You know you may be right, a country that had no Army or Navy or National Govt at all, built an industrial infrastructure up from nothing held off the entire Union Army for four years. Either the North was TOTALLY incompetent or you are full of Sherman.
The build-up of infrastructure didn’t occur until after the Civil War. During the war the south ate itself alive.
As for heroism and incompetence, there was plenty to spare an both sides.
