9Battle of Teutoburg ForestIn September 9 AD, three Roman legions under Publius Quinctilius Varus are ambushed and annihilated in the forests of Germania by a coalition of Germanic tribes led by Arminius — a Romanised German who had served in the Roman army. Perhaps 20,000 Romans are killed over three days. Augustus, on hearing the news, repeatedly cried "Varus, give me back my legions!" The Rhine becomes Rome's permanent northern boundary; the Rhine-Danube line, not further conquest, defines the empire's northern edge for four centuries.
