If you are in Canada, the third episode of Perfect Storms called The Lost Legions is on at 2100 ET/PT on Monday on the History Channel in Canada.
AD 9. 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.
I do a lot of talking to camera and wander around the battlefield looking pensive. Nonetheless, it is worth a look. The teaser trailer is below! It is out in the UK on Yesterday in May.
