Picts for this success, gave them a habitation in Albania, where they continued afterwards mixed with the Britons. CHAP. IV.--_Allectus kills Carausius, but is afterwards himself slain in flight by Asclepiodotus._ When the news of these proceedings of Carausius arrived at Rome, the senate commissioned[187] Allectus, with three legions, to kill the tyrant, and restore the kingdom of Britain to the Roman power. No sooner was he arrived, than he fought with Carausius, killed him, and took upon himself the government. After which he miserably oppressed the Britons, for having deserted the commonwealth, and adhered to Carausius. But the Britons, not enduring this, advanced Asclepiodotus, duke of Cornwall, to be their king, and then unanimously marched against Allectus, and challenged him to battle. He was then at London, celebrating a feast to his tutelary gods; but being informed of the coming of Asclepiodotus, he quitted the sacrifice, and went out with all his forces to meet him, and engaged with him in a sharp fight. But Asclepiodotus had the advantage, and dispersed and put to flight Allectus's troops, and in the pursuit killed many thousands, as also king Allectus himself. After this victory, Livius Gallus, the colleague of Allectus, assembled the rest of the Romans, shut the gates of the city, and placed his men in the towers and other fortifications, thinking by these means either to make a stand against Asclepiodotus, or at least to avoid imminent death.

At this summons came the Dimetians, Venedotians, Deirans, Albanians, and all others of the British race. And as soon as they appeared before the duke, he commanded vast numbers of engines to be made, to beat down the walls of the city. Accordingly every one readily executed his orders with great bravery, and made a violent assault upon the city, the walls of which were in a very short time battered down, and a passage made into it. After these preparations, they began a bloody assault upon the Romans, who, seeing their fellow soldiers falling before them without intermission, persuaded Gallus to offer a surrender on the terms of having quarter granted them, and leave to depart: for they were now all killed except one legion, which still held out. Gallus consented to the proposal, and accordingly surrendered himself and his men to Asclepiodotus, who was disposed to give them quarter; but he was prevented by a body of Venedotians, who rushed upon them, and the same day cut off all their heads upon a brook within the
