The document discusses some of the key reasons why the North was ultimately victorious over the South in the American Civil War. The North had significant advantages in population, industry, transportation, and naval power. While the South had some advantages in generals and a defensive strategy, the North had greater resources and a united front around the goals of preserving the Union and abolishing slavery. Pivotal battles like Antietam and Gettysburg turned the tide in the North's favor, and the North's greater population and industrial capacity allowed it to wage a war of attrition that exhausted the South over time.
