You cannot qualify war in harsher terms than I will. War is cruelty, and you cannot refine it; and those who brought war into our country deserve all the curses and maledictions a people can pour out. I know I had no hand in making this war, and I know I will make more sacrifices today than any of you to secure peace. But you cannot have peace and a division of our country. If the United States submits to a division now, it will not stop, but will go on until we reap the fate of Mexico, which is eternal war. The United States does and must assert its authority, wherever it once had power; for, if it relaxes one bit to pressure, it is gone, and I believe that such is the national feeling.

Letter to the City of Atlanta (September 1864)
