 The destruction that occurred in Gaul and the lack of an effective response from the court in Ravenna lent support to the rebellion of Constantine III in Britain, which Stilicho proved unable to quash.As Constantine moved his forces into Gaul, Stilicho sent his subordinate Sarus to oppose him.Sarus had some initial success, winning a major victory and killing both of Constantine's "magistri militum", but a relief force drove him back and saved the rebellion.
