Jennifer Weber's "Copperheads" (2006) agrees more with Gray and Milton than with Klement. She argues that first, Northern antiwar sentiment was strong, so strong that Peace Democrats came close to seizing control of their party in mid-1864. Second, she shows the peace sentiment led to deep divisions and occasional violence across the North. Third, Weber concluded that the peace movement deliberately weakened the Union military effort by undermining both enlistment and the operation of the draft. Indeed, Lincoln had to divert combat troops to retake control of New York City from the anti-draft rioters in 1863. Fourth, Weber shows how the attitudes of Union soldiers affected partisan battles back home. The soldiers' rejection of Copperheadism and their overwhelming support for Lincoln's reelection in 1864 was decisive in securing the Northern victory and the preservation of the Union. The Copperheads' appeal, she argues, waxed and waned with Union failures and successes in the field.
