Marriage

At some point after the battle, Arminius married a Germanic princess named Thusnelda. Her father was the Cheruscan prince Segestes, who was pro-Roman. But Arminius abducted and then impregnated Thusnelda circa AD 14. This elopement was likely a result of a dispute between Arminius and Segestes who was against their relationship. In May of 15 the Roman general Germanicus captured Thusnelda. At the point of her capture she was pregnant and living with her father, who had taken her back. Arminius deeply grieved the capture of Thusnelda and did not marry again. Tacitus recorded that Arminius was "driven to frenzy" by the loss of his beloved wife. Tacitus states in the Annals:

Arminius, with his naturally furious temper, was driven to frenzy by the seizure of his wife and the foredooming to slavery of his wife's unborn child. He flew hither and thither among the Cherusci, demanding "war against Segestes, war against Cæsar." And he refrained not from taunts.

Thusnelda gave birth to a son named Thumelicus who grew up in Roman captivity. Tacitus describes him as having an unusual story, which he promises to tell in his later writings, but these writings have never been found.
