You could talk about that in that History Sub Forum we got. Unless there is a question about what Generals either side will have in the mod for Hinkel?
I am currently thinking about 4 factions, 2 corps each side. The generals will be important corps commanders like hill, longstreet and reynolds, hancock. The army commanders will be developer units.
While I am pretty sure to use the first and third corps for the south, I am not sure about the second US faction beside reynolds first corps.
