The "Southern Army" typically refers to the military forces of the Confederate States during the American Civil War (1861-1865). This army was formed to defend the Southern states' interests, primarily centered around the institution of slavery and states' rights. Key leaders included General Robert E. Lee and General Thomas "Stonewall" Jackson, who played significant roles in various battles. The Southern Army faced numerous challenges, including limited resources and manpower compared to the Union Army. Despite early successes in battles such as Bull Run and Chancellorsville, the Confederacy ultimately surrendered in 1865, leading to the end of the Civil War and the abolition of slavery in the United States.
