Civil War: Battle of Antietam

Storyline

General Robert E. Lee's first invasion into the North ended in the Battle of Antietam--the bloodiest single day in the Civil War--and in all US history. Just 12 hours of fighting resulted in nearly 23,000 casualties. On September 17, 1862, two determined armies gathered near Sharpsburg, a quiet backwater near Antietam Creek in western Maryland. Union forces were desperate to repel the South's invasion of their territory. The Confederate Army of Northern Virginia, its back to the Potomac River, was fighting for its very existence. Much was at stake. But just why was Antietam such a terrible killing field? Now the latest forensic techniques are shedding new light on the question. Experts from the fields of archaeology, geology, weapons technology, and pathology investigate this uniquely horrific moment in American history.
