sep 17, 1862 - Battle of Antietam
Description:
Being the single bloodiest battle in American history, let alone the civil war, the battle of Antietam marked a drastic shift in the Union's moral, as it was the battle that gave Lincoln the confidence to declare the Emancipation Proclamation, declaring the war to be over the moral issue of Slavery, thus renewing the North's will to fight.
