Loyal Americans marched off to war in 1861 not to conquer the South but to liberate it. So argues Elizabeth R. Varon in Armies of Deliverance, a sweeping narrative of the Civil War and a bold new interpretation of Union and Confederate war aims. Northerners imagined the war as a crusade to deliver the Southern masses from slaveholder domination and to bring democracy, prosperity, and education to the region. As the war escalated, Lincoln and his allies built the case that emancipation would secure military victory and benefit the North and South alike. The theme of deliverance was essential in mobilizing a Unionist coalition of Northerners and anti-Confederate Southerners.
