It was no Insurrection or Rebellion, or even Civil War in any proper sense of these terms... The war... was a war between States regularly organized into two separate Federal Republics... In the beginning, and throughout the contest, the object of the 'Confederates' was to maintain the separate Sovereignty of each State, and the right of self government, which that necessarily carries with it. The object of the 'Federals,' on the contrary, was to maintain a Centralized Sovereignty over all the States on both sides. This was the fundamental principle involved in the Conflict, which must be kept continually in mind.
