My dear General Banks,
Being a poor correspondent is the only apology I offer for not having sooner tendered my thanks for your very successful, and very valuable military operations this year. The final stroke in opening the Mississippi never should, and I think never will, be forgotten. . . .
. . . While I very well know what I would be glad for Louisiana to do, it is quite a different thing for me to assume direction of the matter. I would be glad for her to make a new Constitution recognizing the emancipation proclamation, and adopting emancipation in those parts of the state to which the proclamation does not apply. And while she is at it, I think it would not be objectionable for her to adopt some practical system by which the two races could gradually live themselves out of their old relation to each other, and both come out better prepared for the new. Education for young blacks should be included in the plan. After all, the power, or element, of “contract” may be sufficient for this probationary period; and, by its simplicity, and flexibility, may be the better.
As an anti-slavery man I have a motive to desire emancipation, which pro-slavery men do not have; but even they have strong enough reason to thus place themselves again under the shield of the Union; and to thus perpetually hedge against the recurrence of the scenes through which we are now passing. . . .
For my own part I think I shall not, in any event, retract the emancipation proclamation; nor, as executive, ever return to slavery any person who is free by the terms of that proclamation, or by any of the acts of Congress.
If Louisiana shall send members to Congress, their admission to seats will depend, as you know, upon the respective Houses, and not upon the President.
If these views can be of any advantage in giving shape, and impetus, to action there, I shall be glad for you to use them prudently for that object. Of course you will confer with intelligent and trusty citizens of the State. . . . Still it is perhaps better to not make the letter generally public.
