Theodosius landed at ‘Rutupiæ’ or Richborough, where he had appointed the rendezvous of the troops, and marched upon London. When arrived there he divided his men into several bodies so as to attack different parties of the enemy, who were ravaging the country and returning laden with booty. These he defeated, and wresting from them their plunder, returned to London and sent to the Continent for reinforcements. As soon as the expected troops arrived, Theodosius left London at the head of a powerful and well-selected army, and speedily succeeded in driving the invaders from the provinces, and restoring the cities and fortresses. He then directed his attention to the restoration of the province to its wonted condition of security. The northern frontier was again protected by the stations along the line of the wall between the Forth and Clyde which he renewed, and part of the recovered provinces were formed into a new and separate province, which he termed ‘Valentia,’ in honour of the Emperor Valens. Such is the narrative of the historian Ammianus; but, as the panegyrists threw light upon the expeditions of Constantius, so now the poet Claudian, in his panegyrics upon the illustrious general, supplies further details of the character of his exploits. The Picts, says he, he drove into their own region, to which he gives the poetical name applied to Caledonia of Thule. The Scots he pursued across the sea to the country from whence they proceeded—the island of Ierne; and the Saxons he indicates had formed their headquarters in the islands of Orkney. The stations restored by Theodosius on the frontier he identifies as separating the province from Caledonia by his allusion to the latter word; and it may further be inferred that he had again occupied the castella or outposts with which the Romans garrisoned the territory beyond the wall ceded to them in the campaign of Severus.[93] The inhabitants of a part of the province had joined the invaders in their second invasion under the name of Attacotti, and their territory was now again taken possession of by the Romans. They had exhibited even greater ferocity than the independent tribes, and these he now formed into Roman cohorts, and enlisted as a part of the army.[94]
