"The American people and the Government at Washington may refuse to recognize it for a time but the inexorable logic of events will force it upon them in the end; that the war now being waged in this land is a war for and against slavery."
"Viewing the man from the genuine abolitionist ground, Mr. Lincoln seemed cold, tardy, weak and unequal to the task. But, viewing him from the sentiments of his people, which as a statesman he was bound to respect, then his actions were swift, bold, radical and decisive. Taking the man in the whole, balancing the tremendous magnitude of the situation, and the necessary means to ends, Infinite Wisdom has rarely sent a man into the world more perfectly suited to his mission than Abraham Lincoln."
“To secede from the Union and set up another government would cause war. If you go to war with the United States, you will never conquer her, as she has the money and the men. If she does not whip you by guns, powder, and steel, she will starve you to death. It will take the flower of the country-the young men.”
"Let me tell you what is coming. After the sacrifice of countless millions of treasure and hundreds of thousands of lives you may win Southern independence, but I doubt it. The North is determined to preserve this Union. They are not a fiery, impulsive people as you are, for they live in colder climates. But when they begin to move in a given direction, they move with the steady momentum and perseverance of a mighty avalanche."
(In response to a comment that it was a shame to shoot so many brave men): "'No, shoot them all, I do not wish them to be brave."
William Tecumseh Sherman:
“You people of the South don’t know what you are doing. This country will be drenched in blood, and God only knows how it will end. It is folly, madness, a crime against civilization! You people speak so lightly of war; you don’t know what you’re talking about. War is a terrible thing! You mistake too, the people of the North. They are a peaceable people but an earnest people, and they will fight too. They are not going to let this country be destroyed without a mighty effort to save it.
"I think that Lee should have been hanged. It was all the worse that he was a good man and a fine character and acted conscientiously. It's always the good men who do the most harm in the world."
(Haven't I always said it's the impractical idealists who do the most harm? Bear in mind also that this was said in context of the South's pigheaded refusal to come to a compromise when Lincoln offered them a generous chance after Fort Sumter.)
"But out of that silence rose new sounds more appalling still; a strange ventriloquism, of which you could not locate the source, a smothered moan, as if a thousand discords were flowing together into a key-note weird, unearthly, terrible to hear and bear, yet startling with its nearness; the writhing concord broken by cries for help, some begging for a drop of water, some calling on God for pity; and some on friendly hands to finish what the enemy had so horribly begun; some with delirious, dreamy voices murmuring loved names, as if the dearest were bending over them; and underneath, all the time, the deep bass note from closed lips too hopeless, or too heroic, to articulate their agony...It seemed best to bestow myself between two dead men among the many left there by earlier assaults, and to draw another crosswise for a pillow out of the trampled, blood-soaked sod, pulling the flap of his coat over my face to fend off the chilling winds, and still more chilling, the deep, many voiced moan that overspread the field."
(On the surrender at Appomatox: "...On they come, with the old swinging route step and swaying battle flags. In the van, the proud Confederate ensign. Before us in proud humiliation stood the embodiment of manhood; men whom neither toils and sufferings, nor the fact of death could bend from their resolve; standing before us now, thin, worn, and famished, but erect, and with eyes looking level into ours, waking memories that bound us together as no other bond; was not such manhood to be welcomed back into a Union so tested and assured? On our part not a sound of trumpet more, nor roll of drum; not a cheer, nor word, nor whisper or vain-glorying, nor motion of man, but an awed stillness rather, and breath-holding, as if it were the passing of the dead!"
(I can hardly help being proud that this fellow from Maine was also one of the best writers of the war.)
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.”
Pope Gregory XVI:
"We warn and adjure earnestly in the Lord faithful Christians of every condition that no one in the future dare to vex anyone, despoil him of his possessions, reduce to servitude, or lend aid and favour to those who give themselves up to these practices, or exercise that inhuman traffic by which the Blacks, as if they were not men but rather animals, having been brought into servitude, in no matter what way, are, without any distinction, in contempt of the rights of justice and humanity, bought, sold, and devoted sometimes to the hardest labour. Further, in the hope of gain, propositions of purchase being made to the first owners of the Blacks, dissensions and almost perpetual conflicts are aroused in these regions.
We reprove, then, by virtue of Our Apostolic Authority, all the practices above-mentioned as absolutely unworthy of the Christian name. By the same Authority We prohibit and strictly forbid any Ecclesiastic or lay person from presuming to defend as permissible this traffic in Blacks under no matter what pretext or excuse, or from publishing or teaching in any manner whatsoever, in public or privately, opinions contrary to what We have set forth in this Apostolic Letter."
