The single bloodiest day of the American Civil War was the Battle of Antietam. Fought on September 17, 1862, this battle marked a significant moment in the war due to the staggering number of casualties. Over 23,000 soldiers were killed, wounded, or missing by the end of the day. The Battle of Antietam was crucial not only because of its bloodshed but also because it provided President Abraham Lincoln with the opportunity to issue the Emancipation Proclamation. This pivotal engagement halted the Confederate advance into the North and is often considered a turning point in the Civil War. In contrast, the other options—Atlanta, Shiloh, and Chancellorsville—while also bloody, did not surpass the toll of the battle at Antietam.
