So if I understand this correctly, when I have a blockade of the Mississippi river (Mississippi Delta hex) or the James River (Ft. Monroe hex), what have I successfully blockaded?
I think that I read somewhere that I have only blockaded that space/hex and not what is "upstream". Is that correct? Will this have no impact on New Orleans or Richmond?
Also, if I capture forts that control the rivers leading to these or other inland ports, what effect will I have?
P.S. Awesome game fellas. I got it this week and have been playing it nonstop.
