Battle of Antietam gave Lincoln the confidence to order the emancipation of the slaves.
Lincoln first discussed the Proclamation with his cabinet in July 1862. He believed he needed a Union victory on the battlefield to make his decision positive. The Battle of Antietam, in which Union forces rejected the Confederate invasion of Maryland, gave him the opportunity to issue a preliminary proclamation on September 22, 1862.
