The Union’s outcome at Antietam gave President Lincoln the opportunity to announce the Emancipation Proclamation from a position of strength. He issued the preliminary proclamation shortly after the battle in September 1862, and it took effect on January 1, 1863. Lee’s surrender and Sherman’s total-war campaign happened later, and Gettysburg was a Union victory, not a Union loss.
