1063
This year went Earl Harold, after mid-winter, from Gloucester to Rhyddlan; which belonged to Griffin: and that habitation he burned, with his ships and all the rigging belonging thereto; and put him to flight. Then in the gang-days went Harold with his ships from Bristol about Wales; where he made a truce with the people, and they gave him hostages. Tosty meanwhile advanced with a land-force against them, and plundered the land. But in the harvest of the same year was King Griffin slain, on the nones of August, by his own men, through the war that he waged with Earl Harold. He was king over all the Welsh nation. And his head was brought to Earl Harold; who sent it to the king, with his ship's head, and the rigging therewith. King Edward committed the land to his two brothers, Blethgent and Rigwatle; who swore oaths, and gave hostages to the king and to the earl, that they would be faithful to him in all things, ready to aid him everywhere by water and land, and would pay him such tribute from the land as was paid long before to other kings.
