The South did not have an advantage over the North in terms of most of the nation's factories being in the South, the South having a greater population, or the South having superior transportation systems. However, the South did have an advantage in that most of the nation's experienced military leaders were southerners. Many of the most prominent military leaders of the Civil War, including Robert E. Lee and Stonewall Jackson, were from the South and had extensive military experience prior to the war. This gave the South an advantage in terms of military leadership, at least in the early years of the war.
