We live far enough away from those times of test and trial to know that sincerity and honesty did not all lie on either side. We know the conflicts of loyalties, traditions, ancestry, and interest which drew men to one side and the other. I doubt if there ever was another so great and elemental a conflict from which men emerged with so much of mutual respect, with so little of bitterness and lingering hostility. The struggle brought the whole Nation at last to see that its only assurance was in unity. United, it could go its way in all security; divided, both sections becoming the prey of jealousy and intrigue, would have dissipated all the power they now have for good in the world.
