Secret Tunnel Warfare
Season 43 Episode 1 | 52m 52sVideo has Closed Captions
In WW1 Allied troops tunneled under enemy lines to create the biggest explosion ever seen.
During World War I, the Allies and Germans repeatedly struggled to break the hideous stalemate of trench warfare. In the winter of 1916, Allied engineers devised a massive surprise attack: over 1 million pounds of explosives hidden in secret tunnels driven under German lines. Building the tunnels was desperate work, with tunnelers at constant risk from flooding, cave-ins, and enemy digging teams.
