About the series
In this 1992 one-shot from DC, writer Elliot S! Maggin and artist Alan Weiss send Batman back in time to the American Civil War. The Caped Crusader finds himself entangled in a conflict between Union and Confederate forces, testing his code against a war without clear heroes. It's a compact, high-concept Elseworlds tale that drops the Dark Knight into a historical crucible.
