Confederate artillery from the high ground along the Hagerstown Pike near Dunker Church helped repulse the early morning attack of the Union I Corps, which included a company of York Countians serving in the 12th Pennsylvania Reserves.
The Battle of Antietam has been termed "America's Bloodiest Day," with more than 22,000 American casualties falling on September 17, 1862. More Americans fell that day than at D-Day, any single day of World Wars I or II, any day during Viet Nam, or any other day in any war in the country's history. Among those men to fall during the savage encounter at Antietam were some locals from York County, Pennsylvania.
