This special Unexplained History broadcast follows biological warfare from its disputed Bronze Age beginnings through medieval sieges, colonial smallpox, Japan's Unit 731, Western programs, and the treaty intended to end them. The second half investigates the Soviet biological weapons system, the Aralsk smallpox outbreak, the Sverdlovsk anthrax disaster, defectors, inspections, and accidents at Russian research facilities.
