Battle of the Teutoburg Forest

The Battle of the Teutoburg Forest took place two millenniums ago in the autumn of 9 AD, when an alliance of Germanic tribes led by Arminius, the son of Segimer of the Cherusci, ambushed and destroyed three Roman legions led by Publius Quinctilius Varus. The battle began a seven-year war which established the Rhine as the boundary of the Roman Empire for the next four hundred years, until the decline of the Roman influence in the West.
