Of the matter now to be treated of, most noble consul, Geoffrey of Monmouth shall be silent; but will, nevertheless, though in a mean style, briefly relate what he found in the British book above-mentioned, and heard from that most learned historian, Walter, archdeacon of Oxford, concerning the wars which this renowned king, upon his return to Britain after this victory, waged against his nephew. As soon, therefore, as the report, of this flagrant wickedness reached him, he immediately desisted from his enterprise against Leo, king of the Romans; and having sent away Hoel, duke of the Armoricans, with the army of Gaul, to restore peace in those parts, returned back with speed to Britain, attended only by the kings of the islands, and their armies. But the wicked traitor, Modred, had sent Cheldric, the Saxon leader, into Germany, there to raise all the forces he could find, and return with all speed: and in consideration of this service, had promised him all that part of the island, which reaches from the Humber to Scotland, and whatever Hengist and Horsa had possessed of Kent in the time of Vortigern. So that he, in obedience to his commands, had arrived with eight hundred ships filled with pagan soldiers, and had entered into covenant to obey the traitor as his sovereign; who had also drawn to his assistance the Scots, Picts, Irish, and all others whom he knew to be enemies to his uncle. His whole army, taking pagans and Christians together, amounted to eighty thousand men; with the help of whom he met Arthur just after his landing at the port of Rutupi, and joining battle with him, made a very great slaughter of his men. For the same day fell Augusel, king of Albania, and Walgan, the king's nephew, with innumerable others. Augusel was succeeded in his kingdom by Eventus, his brother Urian's son, who afterwards performed many famous exploits in those wars. After they had at last, with much difficulty, got ashore, they paid back the slaughter, and put Modred and his army to flight. For, by long practice in war, they had learned an excellent way of ordering their forces; which was so managed, that while their foot were employed either in an assault or upon the defensive, the horse would come in at full speed obliquely, break through the enemy's ranks, and so force them to flee. Nevertheless, this perjured usurper got his forces together again, and the night following entered Winchester. As soon as queen Guanhumara heard this, she immediately, despairing of success, fled from York to the City of Legions, where she resolved to lead a chaste life among the nuns in the church of Julius the Martyr, and entered herself one of their order.
