The historic Burnside Bridge, built in 1836, played a key role in the Battle of Antietam on September 17, 1862, when a small number of Confederate soldiers held off repeated attempts by the Union Army to take the bridge by force. This Battle remains the bloodiest single-day battle in American history. (Image taken by Patrick R. Kane on 21 Aug 2010 with COOLPIX S570 at ISO 80, f5.4, 1/320 sec and 5mm)
