Throughout history certain battles are generally regarded as having seriously altered the course of history. One such occurred on September 9th in what is now Germany.

On this day in history:

On September 9, 4 (CE), an alliance of Germanic tribes under the leadership of Arminius utterly and completely annihilated three Roman Legions, six cohorts of Roman auxiliaries, and three squadrons of Roman cavalry under the leadership of one Publius Quinctilius Varus (yes, that damn Varus). For the record, that damn Varus was a truly horrible piece of work and thoroughly merited such a fate. Even though their eagles were eventually recovered, two of the lost legions (Legio XVII and Legio XIX) were never reconstituted. Legio XVIII was briefly reconstituted under Nero, but later disbanded. This is generally regarded as Rome's greatest military defeat. Following their victory, the Germans then made a complete sweep or all Roman forts, towns and garrisons east of the Rhine and constituted a serious threat to cross the Rhine and invade "Gaul". The continuous steady expansion of the Roman Empire was stopped cold in the Region, and Rome never again attempted to conquer, hold, and rule German territory east of the Rhine outside of Mainz, which was established on the eastern bank of the Rhine some 80 years later.
