A better question is what those veterans would think if they could see the USA as it is NOW. The Yankees would be unable to lift their heads, a state of total shame. The Southerners would be spitting mad.
Admit it. If you had been there you would have spent your whole time taking rock shots at every Yankee you could find, and telling everyone within earshot how you hated the Constitution and the Declaration of Independence and everything to do with the country.
