When Arminius was about ten years old he saw something amazing. He saw a Roman Legion fighting in Germany get into trouble. It taught him two key lessons. The first was that given the right terrain and the right tactics the Romans would struggle to bring their discipline and strategic advantages to bear on the conflict. Second he learnt that the Romans could be beaten, the myth of their invincibility had been shattered in his mind.
Soon after Arminius was taken by the Romans as a hostage to ensure the good behaviour of his tribe the Cherusci. As a noble born he was treated well by the Romans who gave him a Roman education, citizenship and status. When he came of age he joined the Roman Army and served in various theatres of conflict probably earning his Roman name Arminius in Arminia, his real name is lost to history. He returns to German around 8AD to serve under Publius Quinctilius Varus. During his time away he has learnt how the Roman Army operates and developed a strong understanding of its strengths and weaknesses.

In addition to his understanding of the Roman Army, Arminius understood the Germanic tribes and was able to negotiate with them bringing together a confederations of normally fiercely competitive peoples. With his allies he began to plot a resistance to the Romans that would prevent Germanic lands from falling under the control of Rome. The Roman Empire under Augustus was at an all time high. It was absorbing new lands and defeating enemies that had been a thorn in its side for generations. Conquest in the north, of Germanic lands, seemed inevitable.
Arminius’ opportunity came with a rebellion in the Balklands. Eight of the eleven legions under Varus were redeployed to deal with this threat leaving three to control the Germanic boarder and project Roman power. In 9AD Arminius brought Varus a false report of a rebellion in northern Germany. Despite being warned by Arminius’ father in law that he was untrustworthy Varus did not question the report. Varus had the option to divert the march of the legions enabling them to deal with the supposed rebellion and still make it to the winter camp which he did. Thus he walked into the trap which would result in a titanic Roman defeat.

The Romans were ambushed in dense woodland where they could not utilise their formations. The fighting was intense and controlled by Arminius who knew the route of the march and arranged for the attacks to occur at the worst possible locations for the Romans. The Romans were allowed no rest in contrast to the Germans who were able to bring fresh troops into battle which inevitably led to a rout. When he realised that all was long Varus committed suicide.

The loss of three legions on their northern boarder was a disaster for the Roman Empire. They could not protect their cities and forts north of the rhine nor could they initially prevent a German raid into Gaul. When he heard the news Emperor Augustus was shocked and was found banging his head against a wall repeating “Publius Quinctilius Varus give me back my legions”. Retreating Roman soldiers under Lucius Cedicius held up the Germans giving time for Lucius Nonius to organise a defence of the Rhine which they held until reinforcements under Tiberius arrived.
After the battle the Romans attempted to reassert control through punitive raids under Germanicus. These raids recovered two legionary eagles captured by the Germans. The last eagle was recaptured during the reign of Claudius. Germanicus was very successful and this attracted the envy of the new emperor Tiberius who recalled him. Tiberius then set the boarder with Germany at the Rhine and the northern expansion of Rome was at an end.
Arminius himself died at the hands of his allies. He was probably poisoned by his relatives because of his growing power and autocracy. The Romans fought hard to destroy his federation and thus limit the power of the German tribes. The legacy of Arminius is that Germany was never fully Romanised and Roman expansion was stopped in its tracks.
