"I, Nennius, disciple of St. Elbotus, have endeavoured to write some extracts which the dullness of the British nation had cast away, because teachers had no knowledge, nor gave any information in their books about this island of Britain. But I have got together all that I could find as well from the annals of the Romans as from the chronicles of the sacred fathers, Hieronymus, Eusebius, Isidorus, Prosper, and from the annals of the Scots and Saxons, and from our ancient traditions. Many teachers and scribes have attempted to write this, but somehow or other have abandoned it from its difficulty, either on account of frequent deaths, or the often recurring calamities of war. I pray that every reader who shall read this book, may pardon me, for having attempted, like a chattering jay, or like some weak witness, to write these things, after they had failed. I yield to him who knows more of these things than I do."
—"The Apology of Nennius", Historia Brittonum
At that time, the Saxons greatly increased in Britain, both in strength and numbers. And Octa, after the death of his father Hengist, came from the sinistral part of the island to the kingdom of Kent, and from him have proceeded all the kings of that province, to the present period. Then it was that the magnanimous Arthur, with all the kings and military force of Britain, fought against the Saxons. And though there were many more noble than himself, yet he was twelve times chosen their commander, and was as often conqueror.
