Lincoln was prompted to issue the Emancipation Proclamation as a result of this.
The finest example of how the Battle of Antietam influenced President Abraham Lincoln's perspective on the war is his decision to issue the Emancipation Proclamation.
On September 22, 1862, President Abraham Lincoln issued the Emancipation Proclamation after the Union Troops defeated the Confederate soldiers at the Battle of Antietam. The conflict was also known as the September 1862 Battle of Sharpsburg. The effort by the South to attack the North only lasted one day. Historians consider this to be the bloodiest single-day war ever fought. The new Emancipation Proclamation guaranteed freedom to all slaves in the United States.
