The arrangements of Theodosius sufficed to ensure the safety of the province for some fourteen years. That much damage had been inflicted is certain, and perhaps Britain never entirely recovered from the effects of the invasions of 364-368. It has been suggested that Deva, Viroconium, and other towns in the west, had been destroyed by the Scots; but this seems very doubtful. A fact to be noted is that there was already a considerable Teutonic element in the island in the shape of many _numeri_ formed out of prisoners taken in the chronic wars on the Rhine. In 371 the Emperor Valentinian sent over to Britain a whole Alemannic sub-tribe. In 383 the Army of Britain revolted against Gratianus, the successor of Valentinian I., and proclaimed as Emperor an able Spanish general, Magnus Clemens Maximus, who held high command in the island, but had been passed over by Gratian’s ministers for promotion. The Picts and Scots seized the opportunity to renew their raids, but were repelled by Maximus, who then, however, crossed to Gaul to expel Gratian. The troops joined him, Gratian was murdered by one of his officers, and Maximus became supreme over Gaul and Spain. Gratian’s brother, Valentinian II., retained Italy for a while, but in 387 Maximus expelled him. He hoped, perhaps, to repeat the deeds of Constantine I., who had conquered the whole empire from the West, but fate decreed otherwise. In 388 Theodosius I., Emperor of the East, son of Count Theodosius, came up against him, and he was defeated at Aquileia, captured, and executed.
