Well, they didn't have email or texts back then so news moved slow. I'm not sure "a lot" would be correct but of course there were negotiations of sorts. I believe the Union troops were allowed to leave without resistance. SC wasn't intent of starting a war but continuing a way of life. Again, slavery would end organically. And I get not wanting to wait that long. But killing Americans did not have to start in 4/1861.
And, yes, there was a bigger picture. I'm just bothered by the fact that Lincoln is looked at as a great President when patience, and lack of loss of American life, could have been used. Dems have fits over Dubya killing American soldiers by sending them to fight a war that was not ours. Lincoln's war was for human decency but it wasn't for American people.
