Chap. I Cadwan Acquires by Treaty All Britain on This Side of the Humber, and Ethelfrid the Rest
After this all the princes of the Britons met together at the city of Legecester, and consented to make Cadwan their king, that under his command they might pursue Ethelfrid beyond the Humber. Accordingly, as soon as he was crowned, they flocked together from all parts, and passed the Humber; of which when Ethelfrid received intelligence, he entered into a confederacy with all the Saxon kings, and went to meet Cadwan. At last, as they were forming their troops for a battle, their friends came, and made peace between them on these terms: that Cadwan should enjoy that part of Britain which lies on this side of the Humber, and Ethelfrid that which is beyond it. As soon as they had confirmed this agreement with an oath made to their hostages, there commenced such a friendship between them, that they had all things common. In the meantime it happened, that Ethelfrid banished his own wife and married another, and bore so great a hatred to her that was banished, that he would not suffer her to live in the kingdom of Northumberland. Whereupon she, being with child, went to king Cadwan, that by his mediation she might be restored to her husband. But when Ethelfrid could by no means be brought to consent to it, she continued to live with Cadwan, till she was delivered of the son which she had conceived. A short time after her delivery, Cadwan also had a son born to him by the queen, his wife. Then were the two boys brought up together in a manner suitable to their royal birth, one of which was called Cadwalla, the other Edwin. When they were nearly arrived at men’s estate, their parents sent them to Salomon, king of the Armorican Britons, that in his court they might learn the discipline of war, and other princely qualifications. This prince, therefore, received them graciously, and admitted them to an intimacy with him; so that there was none of their age in the whole court, that had a free access, or more familiarly discoursed with the king than they. At last he himself was an eye-witness of their exploits against the enemy, in which they very much signalized their valour.
