Soon after that, in this year, went the army from Wirheal into North-Wales; for they could not remain there, because they were stripped both of the cattle and the corn that they had acquired by plunder. When they went again out of North- Wales with the booty they had acquired there, they marched over Northumberland and East-Anglia, so that the king's army could not reach them till they came into Essex eastward, on an island that is out at sea, called Mersey. And as the army returned homeward that had beset Exeter, they went up plundering in Sussex nigh Chichester; but the townsmen put them to flight, and slew many hundreds of them, and took some of their ships. Then, in the same year, before winter, the Danes, who abode in Mersey, towed their ships up on the Thames, and thence up the Lea. That was about two years after that they came hither over sea.
