Not surprised.
"I am naturally anti-slavery. If slavery is not wrong, nothing is wrong. I can not remember when I did not so think, and feel. And yet I have never understood that the Presidency conferred upon me an unrestricted right to act officially upon this judgment and feeling. It was in the oath I took that I would, to the best of my ability, preserve, protect, and defend the Constitution of the United States. I could not take the office without taking the oath. Nor was it my view that I might take an oath to get power, and break the oath in using the power. I understood, too, that in ordinary civil administration this oath even forbade me to practically indulge my primary abstract judgment on the moral question of slavery. I had publicly declared this many times, and in many ways. And I aver that, to this day, I have done no official act in mere deference to my abstract judgment and feeling on slavery. I did understand however, that my oath to preserve the constitution to the best of my ability, imposed upon me the duty of preserving, by every indispensable means, that government---that nation---of which that constitution was the organic law.
Was it possible to lose the nation, and yet preserve the constitution? By general law life and limb must be protected; yet often a limb must be amputated to save a life; but a life is never wisely given to save a limb. I felt that measures, otherwise unconstitutional, might become lawful, by becoming indispensable to the preservation of the constitution, through the preservation of the nation. Right or wrong, I assumed this ground, and now avow it. I could not feel that, to the best of my ability, I had even tried to preserve the constitution, if, to save slavery, or any minor matter, I should permit the wreck of government, country, and Constitution all together. When, early in the war, Gen. Fremont attempted military emancipation, I forbade it, because I did not then think it an indispensable necessity. When a little later, Gen. Cameron, then Secretary of War, suggested the arming of the blacks, I objected, because I did not yet think it an indispensable necessity. When, still later, Gen. Hunter attempted military emancipation, I again forbade it, because I did not yet think the indispensable necessity had come. When, in March, and May, and July 1862 I made earnest, and successive appeals to the border states to favor compensated emancipation, I believed the indispensable necessity for military emancipation, and arming the blacks would come, unless averted by that measure. They declined the proposition; and I was, in my best judgment, driven to the alternative of either surrendering the Union, and with it, the Constitution, or of laying strong hand upon the colored element. I chose the latter."
