Which Battle Resulted in the Bloodiest Single Day in All of American History?

The American Civil War was one of the deadliest wars in history, with an estimated 620,000 soldiers losing their lives. However, there was one battle that resulted in the bloodiest single day in all of American history – the Battle of Antietam.

The Prelude to Antietam

The Battle of Antietam took place on September 17, 1862, near Sharpsburg, Maryland. It was fought between Confederate General Robert E. Lee’s Army of Northern Virginia and Union General George B. McClellan’s Army of the Potomac.

The Confederate Invasion

In the summer of 1862, General Lee decided to invade Maryland to take pressure off Virginia and possibly gain recognition from Great Britain and France. On September 4th, his army crossed the Potomac River into Maryland.

The Union Response

Upon learning of Lee’s invasion, President Abraham Lincoln authorized McClellan to pursue Lee’s army and stop its advance into Union territory. McClellan moved his army quickly and intercepted Lee at Sharpsburg.

The Battle Begins

On September 17th, McClellan attacked Lee’s army near Antietam Creek. The battle raged on for hours with both sides taking heavy casualties.

Bloodiest Single Day in American History

By nightfall, over 23,000 soldiers were killed or wounded – making it the bloodiest single day in all of American history.

The Aftermath

Despite heavy losses on both sides, neither army gained a decisive victory at Antietam. However, it did provide a much-needed boost to the Union cause as it forced Lee to retreat back into Virginia.
