Edwin reigned most gloriously seventeen years over the nations of the English and the Britons, six whereof, as has been said, he also was a soldier in the kingdom of Christ. Caedwalla,(270) king of the Britons, rebelled against him, being supported by the vigorous Penda, of the royal race of the Mercians, who from that time governed that nation for twenty-two years with varying success. A great battle being fought in the plain that is called Haethfelth,(271) Edwin was killed on the 12th of October, in the year of our Lord 633, being then forty-eight years of age, and all his army was either slain or dispersed. In the same war also, Osfrid,(272) one of his sons, a warlike youth, fell before him; Eadfrid,(273) another of them, compelled by necessity, went over to King Penda, and was by him afterwards slain in the reign of Oswald, contrary to his oath. At this time a great slaughter was made in the Church and nation of the Northumbrians; chiefly because one of the chiefs, by whom it was carried on, was a pagan, and the other a barbarian, more cruel than a pagan; for Penda, with all the nation of the Mercians, was an idolater, and a stranger to the name of Christ; but Caedwalla, though he professed and called himself a Christian, was so barbarous in his disposition and manner of living, that he did not even spare women and innocent children, but with bestial cruelty put all alike to death by torture, and overran all their country in his fury for a long time, intending to cut off all the race of the English within the borders of Britain. Nor did he pay any respect to the Christian religion which had sprung up among them; it being to this day the custom of the Britons to despise the faith and religion of the English, and to have no part with them in anything any more than with pagans. King Edwin’s head was brought to York, and afterwards taken into the church of the blessed Peter the Apostle, which he had begun, but which his successor Oswald finished, as has been said before. It was laid in the chapel of the holy Pope Gregory, from whose disciples he had received the word of life.(274)
