Maryland Campaign
The Maryland Campaign, occurring in September 1862 during the American Civil War, was a key military engagement between Union and Confederate forces. Led by General Robert E. Lee, the Confederate Army aimed to invade the North and gain support for their cause. The campaign included the significant Battle of Antietam, which became the bloodiest single-day battle in American history. The Union, commanded by General George McClellan, ultimately halted Lee's advance. Although the battle was tactically inconclusive, it gave President Abraham Lincoln a political advantage, leading to the Emancipation Proclamation that declared freedom for enslaved people in Confederate-held territories.
