Battle of the Teutoburg Forest

The Battle of the Teutoburg Forest (, Hermannsschlacht or Varusschlacht), described as clades Variana (the Varian disaster) by Roman historians, took place in the Teutoburg Forest in 9 CE, when an alliance of Germanic tribes ambushed and decisively destroyed three Roman legions and their auxiliaries, led by Publius Quinctilius Varus. The anti-Roman alliance was led by Arminius, who had acquired Roman citizenship and received a Roman military education, thus enabling him to personally deceive the Roman commander and foresee the Roman army's tactical responses.
