The Battle of the Teutoburg Forest, described as the Varian disaster by Roman historians, took place in 9 A.D., when an alliance of Germanic tribes led by Arminius ambushed and destroyed three Roman legions, along with their auxiliaries, led by Publius Quinctilius Varus. Despite numerous successful campaigns and raids by the Roman army over the Rhine in the years after the battle, the Romans were to make no more concerted attempts to conquer and permanently hold Germania.
