[snip] In the aftermath of the battle, Arminius fought retaliatory invasions by the Roman general Germanicus in the battles of Pontes Longi, Idistaviso, and the Angrivarian Wall, and deposed a rival, the Marcomanni king Maroboduus. Germanic nobles, afraid of Arminius’ growing power, assassinated him in 21 AD. [/snip]
Nice try.
