Chap. VIII Constantine, Having Reduced Rome, Obtains the Empire of the World. Octavius, Duke of the Wisseans, Is Put to Flight by Trahern
Constantine, moved with these and the like speeches, made an expedition to Rome, and reduced it under his power, and afterwards obtained the empire of the whole world. In this expedition he carried along with him three uncles of Helena, viz. Leolin, Trahern, and Marius, and advanced them to the degree of senators. In the meantime Octavius, duke of the Wisseans, rebelled against the Roman proconsuls, to whom the government of the island had been committed, and having killed them, took possession of the throne. Constantine, upon information of this, sent Trahern, the uncle of Helena, with three legions to reduce the island. Trahern came to shore near the city, which in the British tongue is called Kaerperis, and having assailed it, took it in two days. This news spreading over the whole country, king Octavius assembled all the forces of the land, and went to meet him not far from Winchester, in a field called in the British tongue Maisuriam, where he engaged with him in battle, and routed him. Trahern, upon this loss, betook himself with his broken forces to his ships, and in them made a voyage to Albania, in the provinces of which he made great destruction. When Octavius received intelligence of this, he followed him with his forces, and encountered him in Westmoreland, but fled, having lost the victory. On the other hand, Trahern, when he found the day was his own, pursued Octavius, nor ever suffered him to be at rest till he had dispossessed him both of his cities and crown. Octavius, in great grief for the loss of his kingdom, went with his fleet to Norway, to obtain assistance from king Gombert. In the meantime he had given orders to his most intimate adherents to watch carefully all opportunities of killing Trahern, which accordingly was not long after done by the magistrate of a certain privileged town, who had a more than ordinary love for him. For as Trahern was one day upon a journey from London, he lay hid with a hundred men in the vale of a wood, through which he was to pass, and there fell upon him unawares, and killed him in the midst of his men. This news being brought to Octavius, he returned back to Britain, where he dispersed the Romans, and recovered the throne. In a short time after this, he arrived to such greatness and wealth that he feared nobody, and possessed the kingdom until the reign of Gratian and Valentinian.
