They were the pride of Roman Britain, seasoned warriors with a fearsome reputation. But at some point in the second century CE, the 9th Roman Legion disappeared without a trace. Was it wiped out in the wilds of northern Britain, reassigned and lost in another forgotten battle, or simply dissolved into history's shadows? In this episode, we investigate one of ancient Rome's most enduring mysteries and explore the many theories behind the vanishing of Legio IX Hispana.
