A Free Pass. Entitling the holder to the tender mercies of the Constitutional Purifying Association,
An excerpt from "Copperheads" by Delores Archaimbault and Terry A. Barnhart
Copperhead was a pejorative epithet applied to Northern members of the Democratic party, also known as Peace Democrats, who criticized the presidential administration of Abraham Lincoln for its war policies and who sought an armistice with the Confederacy. A loosely-affiliated group, the Copperheads expressed their views on the war in the press, at political conventions, and in state legislatures. Their views struck a responsive chord among like-minded Democrats in Illinois, Indiana, and Ohio in the period 1862 to 1864, while their Republican opponents considered their ideas and alleged actions as nothing less than treason. Not all those known as Copperheads supported the doctrine of secession, but as a group they found common cause in their objections to the actions of the Lincoln administration.
