And President Lincoln failed to free them there. What year was that? Let me see.....
I think the years that you are looking for is 1864, when the 13th Amendment ending slavery was passed out of the Senate and when Lincoln made ratification of the amenment a plank in the 1864 Republican platform and when he pushed the lame-duck Congress to pass the amendment and send it to the states. And also 1865 when the amendment was sent to the states and ratified.
