Editing Constantius III (section)

===Revolt of Constantine III===
In 411 Constantius was sent by Honorius to put down the revolt of [[Constantine III (Western Roman Emperor)|Constantine III]], who had declared himself emperor in [[Roman Britain|Britain]] in 407.{{sfn|Jones|1992|p=316}} Constantius thereafter led his soldiers to [[Arles]], the capital and residence of Constantine. Upon arriving, he defeated the army of [[Gerontius (magister militum)|Gerontius]], a general who was rebelling against Constantine, before besieging the city.{{sfn|Jones|1992|p=316}}

Constantine refused to surrender, hoping to last until the return of his general [[Edobichus]], who was raising troops in northern [[Gaul]].{{sfn|Bury|1889|p=143}} When Edobichus did return to Arles, he was swiftly defeated by Constantius.{{sfn|Bury|1889|p=144}} Constantine soon after lost much of the remainder of his forces, as his army which had been guarding the [[Rhine]] chose to support the usurper [[Jovinus]] instead, forcing Constantine to surrender. Despite Constantius's assurances that Constantine would be able to safely retire to a [[Monastery|clerical office]], Constantius had him imprisoned, and further had him beheaded during his return to [[Ravenna]], in either August or September 411.{{sfn|Jones|1992|p=316}} Honorius's remaining rivals were soon defeated, with Gerontius committing suicide in Hispania,{{sfn|Jones|1992|p=508}} and Jovinus being defeated by [[Athaulf]], king of the [[Visigoth]]s.{{sfn|Bury|1889|p=144}} Despite this, Honorius was unable to regain control of Britain, nor was any Roman after him.{{sfn|Birley|1980|p=160}}
