Any such thing as a US Civil War based RPG?

I'd probably go with GURPS for a game intended to be grounded in reality, HERO for a more heroic game (or if you're very familiar with HERO already), and maybe a horror system like Chill or Cthuhlu (possibly d20) if you're going for a 'frightening camp fire tale' vibe.

If you already know the background, you only need a generic rules system, therefore I would also go with GURPS, HERO, or Savage Worlds (or any other generic rules system, though I do not know any other off-hand, that's generic enough to be called generic ).
