The beginning of a multi-part series on the Maryland Campaign and the Battle of Antietam. In early September 1862, Confederate General Robert E. Lee invaded Maryland and the resulting battle would have profound consequences for emancipation, the Union cause, and the history of photography. It's the story of the bloodiest day in American history and this episode will sets the stage, covering the series of events that led to the battle itself, a tale of ambition and coincidence that stretches credulity.
