On July 22, 1862, President Abraham Lincoln informs his chief advisors and cabinet that he will issue a proclamation to free enslaved people, but adds that he will wait until the Union Army has achieved a substantial military victory to make the announcement.

Attempting to stitch together a nation mired in a bloody civil war, Abraham Lincoln made a last-ditch, but carefully calculated, executive decision regarding the institution of slavery in America. At the time of the meeting with his cabinet, things were not looking good for the Union. The Confederate Army had overcome Union troops in significant battles and Britain and France were set to officially recognize the Confederacy as a separate nation.
