This is the largely untold story of a war waged by secret agents and spies on both sides of the Mason Dixon Line. These are tales of hidden conspiracies of terror that specifically targeted the civilian populations. Engineers of chemical weapons, new-fangled explosives and biological warfare competed to topple their enemy. With insight from Civil War authorities, we debunk the long-held image of a romantic and gentlemanly war. To revisit the past, we incorporate written sources, archival photographs and newspaper headlines. Our reenactments bring to life key moments in our historical characters' lives and in each of the horrific terrorist plots.
