As the Roman Empire expands its reaches into what is now Germany, its legions are faced with ferocious Germanic tribesmen. In 9 AD, their chieftain, Arminius, raised in Rome as a hostage of peace, uses his Roman military training to slaughter the Roman General Varus' army at Teutoburg Forest. This landmark battle establishes the Rhine River as the frontier between the Empire and its growing barbaric enemies. Six years later, when General Germanicus sets out across the Rhine for revenge, he finds heaps of bones and severed skulls nailed to trees - a reminder of the barbarians' victory. But at the Battle of the Weser River, he faces Arminius and wins. Germanicus captures Arminius' pregnant wife, Thusnelda, and parades her through the streets of Rome, as a symbol of his triumph.
