The South did have a chance

Just because the South had a smaller population and less resources compared to the North, doesn't mean that they had absolutely no chance. The South was at a disadvantage, but considering the fact that they had more motivation to fight, the home-field advantage, better generals, and more experienced soldiers meant that they could have used those factors to gain the upper hand in the war. The Confederacy did have strengths of their own so they weren't completely hopeless.
