Dunker Church is one of
the most recognisable landmarks from the Battle of Antietam (also
known as the Battle of Sharpsburg), which occurred on 17th September
1862 near Sharpsburg, Maryland, during the American Civil War. It
was the first major battle to take place on Union soil and remains
the bloodiest day in American military history, with approximately
23,000 casualties. Commanded by Union Major General George B.
McClellan and Confederate General Robert E. Lee, the battle was part
of Lee's first invasion of the North. Despite McClellan’s numerical
advantage, the battle ended inconclusively, with both sides
suffering heavy losses. However, it provided a crucial morale boost
for the Union and led to President Abraham Lincoln issuing the
Emancipation Proclamation, which transformed the war into a fight
for freedom.
