Who were the Copperhead?

•The "Copperheads" were Northern Democrats who opposed the war and called for reuniting the states through negotiation rather than force. They were called "Copperheads", after the poisonous snake, by the Republican opponents who favored war.

This answer is completely incorrect. The Copperheads were northern Democrats alright, but they demanded peace at any cost, promoted and resisted the draft, encouraged the Union soldiers to desert, met with and accepted money from confederate agents, tried to assist confederate soldiers in taking over their prisons and escaping. The republicans did not favor war as the previous writer states, they favored keeping the union in one piece and that would entail war - big difference. No one favors war, it is just that some choose to run away from it, and others choose to defend what is right.
