It [the Civil War] was a heroic struggle; and, as is inevitable with all such struggles, it had also a dark and terrible side. Very much was done of good, and much also of evil; and, as was inevitable in such a period of revolution, often the same man did both good and evil. For our great good fortune as a nation, we, the people of the United States as a whole, can now afford to forget the evil, or, at least, to remember it without bitterness, and to fix our eyes with pride only on the good that was accomplished.
