The '''Battle of Antietam''' took place on September 17, 1862 during the [[American Civil War]], when General [[Robert E. Lee]] took his Army of Northern Virginia and attempted the first Confederate invasion of the North.  More than 23,000 soldiers were killed, wounded or missing after twelve hours of savage combat on what would be called the single bloodiest day in American history.

This was a pivotal strategic victory for the North, forcing the South to retreat back across the [[Potomac River]].  However, the Union General McClellan blundered by not pursuing Lee's army further.
