Since this comes up so often on the Mike Church Show on Sirius/XM I thought I'd go ahead and add this to the site's archives. Notice that the Great Emancipator does not care which method of dealing with the issue of slavery is used to "save the union". It should also come as an intellectual sledgehammer to the head that regardless of his "intentions" Lincoln did NOT save "The Union" because when his reign of fire was concluded federalism was on it's way to the grave and the Southern States ceased to exist as soverign-insular political entities and instead became satellite offices for the National Government.

Lincoln's Letter to Horace Greeley

Executive Mansion,
Washington, August 22, 1862.

Hon. Horace Greeley:
Dear Sir.

I have just read yours of the 19th. addressed to myself through the New-York Tribune. If there be in it any statements, or assumptions of fact, which I may know to be erroneous, I do not, now and here, controvert them. If there be in it any inferences which I may believe to be falsely drawn, I do not now and here, argue against them. If there be perceptable in it an impatient and dictatorial tone, I waive it in deference to an old friend, whose heart I have always supposed to be right.

As to the policy I "seem to be pursuing" as you say, I have not meant to leave any one in doubt.

I would save the Union. I would save it the shortest way under the Constitution. The sooner the national authority can be restored; the nearer the Union will be "the Union as it was." If there be those who would not save the Union, unless they could at the same time save slavery, I do not agree with them. If there be those who would not save the Union unless they could at the same time destroy slavery, I do not agree with them. My paramount object in this struggle is to save the Union, and is not either to save or to destroy slavery. If I could save the Union without freeing any slave I would do it, and if I could save it by freeing all the slaves I would do it; and if I could save it by freeing some and leaving others alone I would also do that. What I do about slavery, and the colored race, I do because I believe it helps to save the Union; and what I forbear, I forbear because I do not believe it would help to save the Union. I shall do less whenever I shall believe what I am doing hurts the cause, and I shall do more whenever I shall believe doing more will help the cause. I shall try to correct errors when shown to be errors; and I shall adopt new views so fast as they shall appear to be true views.

I have here stated my purpose according to my view of official duty; and I intend no modification of my oft-expressed personal wish that all men every where could be free.

Yours,
A. Lincoln.
