I am often suspicious of those in favour of peace. Too often what they really are just partisans for the other side. Copperheads were a group of Northerns in the US civil war who wanted an immediate peace because they were on the side of the South.
Copperhead Dem Candidate Summer 1864:
"Sherman got lucky with Atlanta, just wait until his logistics catches up with him and he's trapped out there in the middle of Georgia. Those valiant Southerners will chew him up.
This war is too expensive and nothing has been achieved. Lincoln needs to meet with Jefferson Davis and just accept the reality of southern secession. Wars never solve anything and those negroes aren't worth a drop of a white man's blood."
