Slavery was wrong, especially the particularly cruel type which pervaded Americas especially in the Caribbean. It made slavery in the Anciant world (Rome, for example) look gentile.
Still, when one talks of the greatest modern military minds/strategists in history, countries like Germany, France, America, England come up at the top, and you cant earn that place without including the feats of the great Confederate Generals. Likewise, Italy, for example. comes at the bottom, not considering Ancient Rome.
The only reason the north won was they had more industry, people (especially waves of irish immigrants , starving to do anything to eat, including enlisting), and money. The South beat the north strategically by a mile given the limited resources they had to work with.
Not siding for the old south, hehe, just giving credit where it belongs, IMO. Im glad they lost, like Nazi Germany.
