Its been used for nationalist propaganda across the ages and its just been dramatised for Netflix, but what do we actually know about the Battle of Teutoburg Forest? For a start, where was it? Dr Joanne Ball, from the University of Liverpool is a battlefield archaeologist. In this episode she takes Tristan through this story of the betrayal and destruction of three of Emperor Augustus’ Roman legions - under the leadership of Varian - by a Germanic alliance led by Arminius, a Germanic auxiliary officer brought up as a hostage of the Roman Empire. Together they explore the circumstances which led the Roman leaders to trust a Germanic subject against his fellow Germanic nationals. They also go through the evidence which places the ambush at Kalkriese and the battle’s extensive legacy, some of which stems from conflicting accounts of its location.
