The document summarizes key aspects of the American Civil War between 1861-1865. It describes advantages held by the Union including larger population and industrial capacity, as well as key Confederate generals like Robert E. Lee and Thomas Jackson. Though the South had local advantages in familiarity with terrain, their population and industrial base were much smaller. Major battles like Gettysburg and Vicksburg were turning points that weakened the South until Lee surrendered in 1865, unifying the country and abolishing slavery while increasing federal power.
