Therefore Ethelbert, king of Kent, when he saw that the Britons disdained subjection to Augustine, and despised his preaching, was highly provoked, and stirred up Ethelfrid, king of the Northumbrians, and the other petty kings of the Saxons, to raise a great army, and march to the city of Bangor, to destroy the abbat Dinooth, and the rest of the clergy who held them in contempt. At his instigation, therefore, they assembled a prodigious army, and in their march to the province of the Britons, came to Legecester, where Brocmail, consul of the city, was awaiting their coming. To the same city were come innumerable monks and hermits from several provinces of the Britons, but especially from the city of Bangor, to pray for the safety of their people. Whereupon Ethelfrid, king of the Northumbrians, collecting all his forces, joined battle with Brocmail, who, having a less army to withstand him, at last quitted the city and fled, though not without having made a great slaughter of the enemy. But Ethelfrid, when he had taken the city, and understood upon what occasion the monks were come thither, commanded his men to turn their arms first against them; and so two hundred of them were honoured with the crown of martyrdom, and admitted into the kingdom of heaven that same day. From thence this Saxon tyrant proceeded on his march to Bangor; but upon the news of his outrageous madness, the leaders of the Britons, viz. Blederic, duke of Cornwall, Margadud, king of the Demetians, and Cadwan, of the Venedotians, came from all parts to meet him, and joining battle with him, wounded him, and forced him to flee; and killed of his army to the number of ten thousand and sixty-six men. On the Britons' side fell Blederic, duke of Cornwall, who was their commander in those wars. BOOK XII. CHAP.
