In it, Arvandus set out to dissuade Euric, king of the Visigoths, from concluding peace with the Western Roman Emperor, urging that instead, he should attack the Britons north of the Loire.
The letter asserted that the Law of Nations called for a division of Gaul between the Visigoths and Burgundians.
At his trial, Arvandus was found guilty and was stripped on the spot of all the privileges pertaining to his prefecture, and consigned to the common jail to await execution.
Possibly this was a result of his undistinguished birth, but the great majority of the Gauls would have learned from Avitus' example, and realized that the day for such adventures was long past.
"At the order of Anthemius, Arvandus, who had attempted to become emperor, was sent into exile" ("Arabundus imperium temptans iussu Anthemii exilio deportatur").
