Old English Chronicles
Aurelius Ambrosius and Uther Pendragon flee from Vortigern
After this, breaking into Constans' bed-chamber, they fell upon him and killed him, and carried his head to Vortigern. At the sight of it, he put on a mournful countenance, and burst forth into tears, though at the same time he was almost transported with joy. However, he summoned together the citizens of London, (for there the fact was committed,) and commanded all the assassins to be bound, and their heads to be cut off for this abominable parricide. In the meantime there were some who had a suspicion, that this piece of villany was wholly the contrivance of Vortigern, and that the Picts were only his instruments to execute it. Others again as positively asserted his innocence. At last the matter being left in doubt, those who had the care of the two brothers, Aurelius Ambrosius, and Uther Pendragon, fled over with them into Lesser Britain, for fear of being killed by Vortigern. There they were kindly received by king Budes, who took care to give them an education suitable to their royal birth.

Now Vortigern, seeing nobody to rival him in the kingdom, placed the crown on his own head, and thus gained the pre-eminence over all the rest of the princes. At
CHAP. X.--_Vortigern takes the Saxons that were new-comers, to his assistance._
In the meantime there arrived in Kent three brigandines, or long galleys, full of armed men, under the command of two brothers, Horsa and Hengist. Vortigern was then at Dorobernia, now Canterbury, which city he used often to visit; and being informed of the arrival of some tall strangers in large ships, he ordered that they should be received peaceably, and conducted into his presence. As soon as they were brought before him, he cast his eyes upon the two brothers, who excelled all the rest both in nobility and gracefulness of person; and having taken a view of the whole company, asked them of what country they were, and what was the occasion of their coming into his kingdom. To whom Hengist (whose years and wisdom entitled him to a precedence), in the name of the rest, made the following answer:--
"Most noble king, Saxony, which is one of the countries of Germany, was the place of our birth; and the occasion of our coming was to offer our service to you or some other prince. For we were driven out of our native country, for no other reason, but that the laws of the kingdom required it. It is customary among us, that when we come to be overstocked with people, our princes from all the provinces meet together, and command all the youths of the kingdom to assemble before them; then casting lots, they make choice of the strongest and ablest of them, to go into foreign nations, to procure themselves a subsistence, and free their native country from a superfluous multitude of people. Our country, therefore, being of late overstocked, our princes met, and after having cast lots, made choice of the youth which you see in your presence, and have obliged us to obey the custom which has been established of old. And us two brothers, Hengist and Horsa, they made generals over them, out of respect to our ancestors, who enjoyed the same honour. In obedience, therefore, to the laws so long established, we put out to sea, and under the good guidance of Mercury have arrived in your kingdom."
