Who said "If I could save the union without freeing any slave, I would do it"?

Who said “If I could save the union without freeing any slave, I would do it”?

Answer:

Abraham Lincoln said these words, which when taken out of context can be slightly confusing. This quote comes from an open letter than Lincoln sent Horace Greeley in which he discussed his approach to the Civil War and that he is committed to doing everything in his power to preserve the Union and all that it stands for regardless of the cost or consequence.
