The constitutional duty is not the only one which requires the States to be restored. There is another consideration which, though of minor importance, is yet of great weight. On the 22d day of July, 1861, Congress declared by an almost unanimous vote of both Houses that the war should be conducted solely for the purpose of preserving the Union and maintaining the supremacy of the Federal Constitution and laws, without impairing the dignity, equality, and rights of the States or of individuals, and that when this was done the war should cease. I do not say that this declaration is personally binding on those who joined in making it, any more than individual members of Congress are personally bound to pay a public debt created under a law for which they voted. But it was a solemn public, official pledge of the national honor, and I can not imagine upon what grounds the repudiation of it is to be justified. If it be said that we are not bound to keep faith with rebels, let it be remembered that this promise was not made to rebels only. Thousands of true men in the South were drawn to our standard by it, and hundreds of thousands in the North gave their lives in the belief that it would be carried out. It was made on the day after the first great battle of the war had been fought and lost. All patriotic and intelligent men then saw the necessity of giving such an assurance, and believed that without it the war would end in disaster to our cause. Having given that assurance in the extremity of our peril, the violation of it now, in the day of our power, would be a rude rending of that good faith which holds the moral world together; our country would cease to have any claim upon the confidence of men; it would make the war not only a failure, but a fraud.
Being sincerely convinced that these views are correct, I would be unfaithful to my duty if I did not recommend the repeal of the acts of Congress which place ten of the Southern States under the domination of military masters. If calm reflection shall satisfy a majority of your honorable bodies that the acts referred to are not only a violation of the national faith, but in direct conflict with the Constitution, I dare not permit myself to doubt that you will immediately strike them from the statute book.
