It was on this date in 1862 that the Battle of Antietam took place, and the end result of the battle was cataclysmic. Between 3,500 and 7,000 were killed in battle and over 16,000 were wounded, thousands of whom would subsequently die due to infection. A Philadelphia native would be one of the commanding generals that day. George McClellan, born in Philadelphia in 1826, was the Commander of the Union in the Battle of Antietam.
