Total nonsense. I posted the relevant parts completely and in context. There was no offer to negotiate the principle issue - the illegal Southern secession. Only a demand to accept it as fact. And if you look at the history of the Southern legislation on this issue, and the way it got watered down over time, then there was no interest on the part of Davis's government to pay for anything that they had already stolen or were demanding.
It is not you in this year to determine the principle issue, and then heap criticism on the peace effort.
