One-eighth of the whole population were colored slaves, not distributed generally over the Union, but localized in the southern part of it. These slaves constituted a peculiar and powerful interest. All knew that this interest was somehow the cause of the war. To strengthen, perpetuate, and extend this interest was the object for which the insurgents would rend the Union even by war, while the Government claimed no right to do more than to restrict the territorial enlargement of it.
Neither party expected for the war the magnitude or the duration which it has already attained. Neither anticipated that the cause of the conflict might cease with or even before the conflict itself should cease. Each looked for an easier triumph, and a result less fundamental and astounding. Both read the same Bible and pray to the same God, and each invokes His aid against the other. It may seem strange that any men should dare to ask a just God's assistance in wringing their bread from the sweat of other men's faces, but let us judge not, that we be not judged. The prayers of both could not be answered. That of neither has been answered fully.
The Almighty has His own purposes. "Woe unto the world because of offenses; for it must needs be that offenses come, but woe to that man by whom the offense cometh." If we shall suppose that American slavery is one of those offenses which, in the providence of God, must needs come, but which, having continued through His appointed time, He now wills to remove, and that He gives to both North and South this terrible war as the woe due to those by whom the offense came, shall we discern therein any departure from those divine attributes which the believers in a living God always ascribe to Him? Fondly do we hope, fervently do we pray, that this mighty scourge of war may speedily pass away. Yet, if God wills that it continue until all the wealth piled by the bondsman's two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said "the judgments of the Lord are true and righteous altogether."
With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation's wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations.
"Journalist Noah Brooks, an eyewitness to the speech, said that as Lincoln advanced from his seat, "a roar of applause shook the air, and, again and again repeated, finally died away on the outer fringe of the throng, like a sweeping wave upon the shore. Just at that moment the sun, which had been obscured all day, burst forth in its unclouded meridian splendor, and flooded the spectacle with glory and with light." Brooks said Lincoln told him the next day, "Did you notice that sunburst? It made my heart jump."
According to Brooks, the audience received the speech in "profound silence," although some passages provoked cheers and applause. "Looking down into the faces of the people, illuminated by the bright rays of the sun, one could see moist eyes and even tearful faces."
Brooks also observed, "But chiefly memorable in the mind of those who saw that second inauguration must still remain the tall, pathetic, melancholy figure of the man who, then inducted into office in the midst of the glad acclaim of thousands of people, and illumined by the deceptive brilliance of a March sunburst, was already standing in the shadow of death."
The final tragedy was that Lincoln was murdered by that nut. The men left behind were unable and/or unwilling to bind up the nation’s wounds.
