The armies met at Heathfield, which is identified with Hatfield Chase on the north-east of Doncaster, on October 12, 633. We have no details of the encounter: we only know that Edwin was defeated, that he and his eldest son Osfrid were slain, and that Cadwallon and his ally roamed in savage wrath over the plains of Yorkshire and Northumberland. The Christian, even more ferocious than the pagan, spared neither sex nor age, recognised no claim to mercy drawn from the profession of one common faith, and vowed (this surely when out of hearing of his ally) that he would root out the whole brood of Angles from the land of Britain.[60] Edwin’s second son fled for refuge to the court of the Mercian king, and was afterwards slain by him, in violation of his sworn promise of protection. The widowed Ethelburga fled to the court of her brother, the King of Kent, under the escort of Paulinus. The royal infants--such was the terror of the times--were separated from their mother, and it was left for a brave soldier named Bass, one of Edwin’s thegns, to bring to the Kentish court the girl Eanfled, her brother Wuscfrea, and their little nephew Yffi, the orphaned son of Osfrid. The widowed queen afterwards sent the boys to the court of her cousin, Frankish Dagobert, that they might be safe from the new rulers of Bernicia, but both died in infancy in that foreign land. As for Paulinus he seems to have bowed his head to the storm of the recrudescent paganism of Northumbria. He vacated his Yorkish see, and was appointed Bishop of Rochester, in succession to Romanus, who had been drowned in the Mediterranean when sent on a mission to Rome. He died in 644. The ill-starred union of Mercian paganism and British fanaticism seemed to have accomplished its purpose. Northumberland was a wilderness and Northumbrian Christianity a vanished dream. CHAPTER IX. OSWALD OF BERNICIA. When the cause of Christianity and, as connected with it, the hope of eventually building in the new England a civilised and well-ordered state seemed at its darkest, light arose from an island in the Hebrides; it spread to a rough storm-beaten rock on the Northumbrian coast; it illumined one of the noblest and loveliest pages in the history of our nation, the reign of Oswald of Bernicia.
