Gettysburg-"Turning point"of the Civil War?

[Gene C]

Good point about Antietam.

At the time many thought Lincoln would not win re-election, I'm not sure many outside of the Confederate leadership knew how desperate the situation was for the south. McClellan wasn't willing to follow the democrat platform which I believe was written by Copperhead Clement Vallandigham. I think there may have been a more prevailing attitude in the north of "we are tired of the war but we've come to far to give up now" But this is my opinion

What was the question we're supposed to answer?
