Gregory quotes Frigeridus about a Roman campaign led by Castinus during the time of Emperor Honorius.

A reason and the result of the campaign is not given, which to all was probably a reaction to a Frankish attack caused by the decline of the Roman army.

[3] Despite the restoration of imperial authority in Spain and Gaul by Constantius III, it seems that border guarding in the north was no longer as thorough as in the period before the Rhine Crossing.

[4] Unlike in the previous period, raids from Germany were no longer followed by punitive expeditions to the attackers' home areas.

[7] In view of other reports that have been handed down, Castinus returned to Ravenna when a political crisis broke out between the western and eastern part of the Roman Empire over the elevation of Constantius III to co-emperor of the west.
