Reveal The Truth, The War for Southern Independence. Union Army General Ulysses S. Grant. Text: "The sole object of this war is to restore the union. Should I be convinced it has any other object, or that the government designs using its soldiers to execute the wishes of the Abolitionists, I pledge to you my honor as a man and a soldier I would resign my commission and carry my sword to the other side." In a letter to the Chicago Tribune, 1862. Slavery was not the cause of the Civil War! Excessive taxes, states rights and lack of fair representation in the federal government led the Southern states to legally secede.
