This episode charts the dramatic events that led to Lincoln's decision to set the slaves free. Convinced by July 1862 that emancipation was now morally and militarily crucial to the future of the Union, Lincoln must wait for a victory to issue his proclamation. But as the year wears on there are no Union victories to be had, thanks to the brilliance of Stonewall Jackson and Robert E. Lee. The episode comes to a climax in September 1862 with Lee's invasion of Maryland. On the banks of Antietam Creek, the bloodiest day of the war takes place, followed shortly by the brightest: the emancipation of the slaves.
