Existing comment: The Copperhead Party:
As the war continued, the federal government became increasingly concerned with "Copperheads," those with anti-war sentiments living within the northern state. Some Copperheads were pro-secession as well, spurring offshoot organizations that supported the Southern cause. Suspicious, the Union began to look closely for suspected traitors, like Valladigham and Milligan, in their midst.
