[snip] Arminius became involved in war with Maroboduus, king of the Marcomanni, and though successful he was subsequently murdered by his own people. [/snip]
There was a Roman price on his head, Rome’s reach was long, Arminius was revived as a cultural icon when the German state needed some supporting myth. A monument was built in the wrong place, commemorating people absorbed or exterminated by the ancestors of modern Germans, or some intervening coat of paint.
Tacitus writes that after the battle Caesar Augustus was heard screaming in his chambers “Arminius, give me back my legions.”
