This he confessed, with many lamentations and sighs, to have been one of his greatest difficulties and impediments in this life, namely, that when he was young and had the capacity for learning, he could not find teachers; but, when he was more advanced in life, he was harassed by so many diseases unknown to all the physicians of this island, as well as by internal and external anxieties of sovereignty, and by continual invasions of the pagans, and had his teachers and writers also so much disturbed, that there was no time for reading. But yet among the impediments of this present life, from infancy up to the present time, and, as I believe, even until his death, he continued to feel the same insatiable desire of knowledge, and still aspires after it. In the year of our Lord's incarnation 867, which was the nineteenth of the life of the aforesaid king Alfred, the army of pagans before mentioned removed from the East-Angles to the city of York, which is situated on the north bank of the river Humber. At that time a violent discord arose, by the instigation of the devil, among the inhabitants of Northumberland; as always is used to happen among a people who have incurred the wrath of God. For the Northumbrians at that time, as we have said, had expelled their lawful king Osbert, and appointed a certain tyrant named Ælla, not of royal birth, over the affairs of the kingdom; but when the pagans approached, by divine Providence, and the union of the nobles for the common good, that discord was a little appeased, and Osbert and Ælla uniting their resources, and assembling an army, marched to York. The pagans fled at their approach, and attempted to defend themselves within the walls of the city. The Christians, perceiving their flight and the terror they were in, determined to destroy the walls of the town, which they succeeded in doing; for that city was not surrounded at that time with firm or strong walls, and when the Christians had made a breach as they had purposed, and many of them had entered into the town, the pagans, urged by despair and necessity, made a fierce sally upon them, slew them, routed them, and cut them down on all sides, both within and without the walls. In that battle fell almost all the Northumbrian warriors, with both the kings and a multitude of nobles; the remainder, who escaped, made peace with the pagans. In the same year, Ealstan, bishop of the church of Sherborne, went the way of all flesh, after he had honourably ruled his see four years, and he was buried at Sherborne.
