Considerable reorganization is undertaken in Britain, including the creation of a new province named Valentia, probably to better address the state of the far north.
Count Theodosius strengthens the defenses of the towns with external towers designed to mount artillery.
Claudian suggests that naval activity took place in northern Britain.
It is possible that Theodosius mounted punitive expeditions against the barbarians and extracted terms from them.
Certainly, the Notitia Dignitatum later records four units of Attacotti serving Rome on the continent.
The Areani were removed from duty and the frontiers refortified with cooperation from border tribes such as the Votadini, marking the career of men such as Padarn Beisrudd (which literally translates as Paternus of the Scarlet Robe), who will serve from 389-39 as a native British governor.
One traditional interpretation identifies Padarn as a Roman (or Romano-British) official of reasonably high rank who had been placed in command of Votadini troops stationed in Clackmannanshire in the 380s or earlier by the Emperor Magnus Maximus.
Alternatively, he may have been a frontier chieftain in the same region who was granted Roman military rank, a practice attested elsewhere along the empire's borders at the time.
