I never was an abolitionist, not even what could be called anti-slavery, but I try to judge fairly and honestly and it became patent in my mind early in the rebellion that the North and South could never live at peace with each other except as one nation, and that without slavery. As anxious as I am to see peace established, I would not therefore be willing to see any settlement until the question is forever settled.
Letter to Elihu Washburne (30 August 1863)
