On September 17, 1862, Robert E. Lee’s Confederate Army of Northern Virginia met George McClellan’s Federal Army of the Potomac along the banks of Antietam Creek near the small town of Sharpsburg, Maryland. The North called it the Battle of Antietam and the South the Battle of Sharpsburg, but they could agree on one thing: it was the single bloodiest day of fighting of the Civil War.

Today Antietam National Battlefield Park is not much changed from its appearance on the eve of the great battle. Farms and fields still make up most of the park land, dotted with the monuments and historical markers that tell the story of what happened here. And a small, simple church of a pacifist sect still stands in the middle of the fields that saw the bloodiest single day in American military history.
