A.D. 911. This year the army in Northumberland broke the truce, and despised every right that Edward and his son demanded of them; and plundered the land of the Mercians. The king had gathered together about a hundred ships, and was then in Kent while the ships were sailing along sea by the south-east to meet him. The army therefore supposed that the greatest part of his force was in the ships, and that they might go, without being attacked, where that ever they would. When the king learned on enquiry that they were gone out on plunder, he sent his army both from Wessex and Mercia; and they came up with the rear of the enemy as he was on his way homeward, and there fought with him and put him to flight, and slew many thousands of his men. There fell King Eowils, and King Healfden; Earls Ohter and Scurf; Governors Agmund, Othulf, and Benesing; Anlaf the Swarthy, and Governor Thunferth; Osferth the collector, and Governor Guthferth. ((A.D. 911. Then the next year after this died Ethelred, lord of the Mercians.)) A.D. 912. This year died Ethered, alderman of Mercia; and King Edward took to London, and to Oxford, and to all the lands that thereunto belonged. This year also came Ethelfleda, lady of the Mercians, on the holy eve called the invention of the holy cross, to Shergate, and built the fortress there, and the same year that at Bridgenorth. A.D. 913. This year, about Martinmas, King Edward had the northern fortress built at Hertford, betwixt the Memer, and the Benwic, and the Lea. After this, in the summer, betwixt gang-days and midsummer, went King Edward with some of his force into Essex, to Maldon; and encamped there the while that men built and fortified the town of Witham. And many of the people submitted to him, who were before under the power of the Danes. And some of his force, meanwhile, built the fortress at Hertford on the south side of the Lea. This year by the permission of God went Ethelfleda, lady of Mercia, with all the Mercians to Tamworth; and built the fort there in the fore-part of the summer; and before Lammas that at Stafford: in the next year that at Eddesbury, in the beginning of the summer; and the same year, late in the autumn, that at Warwick. Then in the following year was built, after mid-winter, that at Chirbury and that at Warburton; and the same year before mid-winter that at Runkorn. ((A.D. 915. This year was Warwick built.)) A.D. 916. This year was the innocent Abbot Egbert slain, before midsummer, on the sixteenth day before the calends of July. The same day was the feast of St. Ciricius the martyr, with his companions. And within three nights sent Ethelfleda an army into Wales, and stormed Brecknock; and there took the king's wife, with some four and thirty others.
