"Why did the Confederacy lose the Civil War? Most historians point to the larger number of Union troops, or to the North's greater industrial might. Now, in The South Vs. the South, a leading authority on the Civil War era offers a critical supplementary viewpoint.

In addition, when the southern border states rejected the Confederacy, half the South's industrial capacity swelled the North's advantage.
