"Against such things, therefore, Severus prepared whatever could be serviceable to the Roman army, but hurtful and detrimental to the designs of the barbarians. And when every thing appeared to him sufficiently arranged for the war, leaving his younger son, named Geta, in that part of the island which was subjugated to the Romans, for the purpose of administering justice and directing other civil matters of the government, giving him as assessors the more aged of his friends; and taking Antoninus with himself, he led the way against the barbarians. His army having passed beyond the rivers and fortresses which defended the Roman territory, there were frequent attacks and skirmishes and retreats on the side of the barbarians. To these, indeed, flight was an easy matter, and they lay hidden in the thickets and marshes through their local knowledge; all which things being adverse to the Romans, served to protract the war."] [Footnote 186: Otherwise called Caracalla.] CHAP. III.--_Carausius advanced to be king of Britain._ At that time there was in Britain one Carausius, a young man of mean birth, who, having given proof of his bravery in many engagements, went to Rome, and solicited the senate for leave to defend with a fleet the maritime coasts of Britain, from the incursions of barbarians; which if they would grant him, he promised to do more for the honour and service of the commonwealth, than by delivering up to them the kingdom of Britain. The senate, deluded by his specious promises, granted him his request, and so, with his commission sealed, he returned to Britain.

By this conduct he encouraged all manner of dissolute fellows to flock to him in hope of plunder, and in a very short time was attended by an army which no neighbouring prince was able to oppose. This made him begin to swell with pride, and to propose to the Britons, that they should make him their king; for which consideration he promised to kill and banish the Romans, and free the whole island from the invasions of barbarous nations. Accordingly obtaining his request, he fell upon Bassianus and killed him, and then took upon him the government of the kingdom. For Bassianus was betrayed by the Picts, whom Fulgenius his mother's brother had brought with him into Britain, and who being corrupted by the promises and presents of Carausius, instead of assisting Bassianus, deserted him in the very battle, and fell upon his men; so that the rest were put into a consternation, and not knowing their friends from their foes, quickly gave ground, and left the victory to Carausius. Then he, to reward the
