Antietam National Battlefield is a national battlefield run by the National Park Service in Maryland.
In the park service’s words
23,000 soldiers were killed, wounded or missing after twelve hours of savage combat on September 17, 1862. The Battle of Antietam ended the Confederate Army of Northern Virginia's first invasion into the North and led Abraham Lincoln to issue the preliminary Emancipation Proclamation.
