 Like the Alamanni, the Quadi were outraged that Valentinian was building fortifications in their territory.They complained and sent deputations to the "magister armorum per Illyricum" Aequitius, who promised to refer the matter to Valentinian.However, the increasingly influential minister Maximinus, now praetorian prefect of Gaul, blamed Aequitius to Valentinian for the trouble, and managed to have him promote his son Marcellianus to finish the project.
