Perfect Storms S01E04 - The Lost Legions: Germany

9 A.D. Three Roman Legions are ambushed and wiped out in a remote German forest during a massive thunderstorm. The severed head of Roman General Varus is sent back to Rome in a box and the Roman attempt to bring Germania into the Empire is stopped dead in its tracks. The battle helps create the boundary between Latin and Germanic Europe that exists to this day.
