Battle of Antietam anniversary recalls Civil War's deadliest encounter
Battle of Antietam anniversary will be commemorated on Monday near Washington, D.C. The Battle of Antietam anniversary will remember over 23,000 soldiers from both the Union and Confederate armies who were killed, wounded, or reported missing.
The midday ceremony at the battlefield caps a long weekend of lectures, hikes and other events devoted to the bloodiest day of combat on US soil.
McPherson has written that Antietam was arguably the most important battle of the war.
More than 23,000 men were reported killed, wounded or missing there on Sept. 17, 1862. Their sacrifices enabled President Abraham Lincoln to announce his preliminary Emancipation Proclamation five days later.
