Anglo-Saxon Chronicle. 1015. This year was the great council at Oxford, Oxfordshire [Map]; where Earldorman Eadric "Streona aka Acquisitive" Mercia betrayed Sigferth and Morcar, the eldest thanes belonging to the Seven Towns. He allured them into his bower, where they were shamefully slain. Then the king took all their possessions, and ordered the widow of Sigferth to be secured, and brought within Malmsbury [Map]. After a little interval, Edmund Etheling (age 25) went and seized [his wife] her, against the [his father] king's (age 49) will, and had her to wife. Then, before the Nativity of St. Mary, went the etheling west-north into the Five Towns⁵⁸, and soon plundered all the property of Sigferth and Morcar; and all the people submitted to him. At the same time came King Knute (age 20) to Sandwich, Kent [Map], and went soon all about Kent into Wessex, until he came to the mouth of the Frome; and then plundered in Dorset, and in Wiltshire, and in Somerset. King Ethelred, meanwhile, lay sick at Corsham, Wiltshire; and Earldorman Eadric "Streona aka Acquisitive" Mercia collected an army there, and Edmund the etheling in the north. When they came together, the alderman designed to betray Edmund the etheling, but he could not; whereupon they separated without an engagement, and sheered off from their enemies. Earldorman Eadric "Streona aka Acquisitive" Mercia then seduced forty ships from the king, and submitted to Knute. The West-Saxons also submitted, and gave hostages, and horsed the army. And he continued there until midwinter.

Note 58. The "seven" towns mentioned above are reduced here to "five"; probably because two had already submitted to the king on the death of the two thanes, Sigferth and Morcar. These five were, as originally, Leicester, Lincoln, Stamford, Nottingham, and Derby. Vid. an. 942, 1013.

Around 1016 [his son] Edmund Wessex was born to King Edmund "Ironside" I of England (age 26) and [his wife] Ealdgyth Unknown.

Anglo-Saxon Chronicle. 1016. This year came King Knute (age 21) with a marine force of one hundred and sixty ships, and Earldorman Eadric "Streona aka Acquisitive" Mercia with him, over the Thames into Mercia at Cricklade, Wiltshire [Map]; whence they proceeded to Warwickshire, during the middle of the winter, and plundered therein, and burned, and slew all they met. Then began Edmund the etheling (age 26) to gather an army, which, when it was collected, could avail him nothing, unless the [his father] king (age 50) were there and they had the assistance of the citizens of London. The expedition therefore was frustrated, and each man betook himself home. After this, an army was again ordered, under full penalties, that every person, however distant, should go forth; and they sent to the king in London, and besought him to come to meet the army with the aid that he could collect. When they were all assembled, it succeeded nothing better than it often did before; and, when it was told the king, that those persons would betray him who ought to assist him, then forsook he the army, and returned again to London. Then rode Edmund the etheling to Earl Utred in Northumbria; and every man supposed that they would collect an army King Knute; but they went into Stafforddhire, and to Shrewsbury, Shropshire [Map], and to Chester, Cheshire [Map]; and they plundered on their parts, and Knute on his. He went out through Buckinghamshire to Bedfordshire; thence to Huntingdonshire, and so into Northamptonshire along the fens to Stamford [Map]. Thence into Lincolnshire. Thence to Nottinghamshire; and so into Northumbria toward York [Map]. When Utred understood this, he ceased from plundering, and hastened northward, and submitted for need, and all the Northumbrians with him; but, though he gave hostages, he was nevertheless slain by the advice of Earldorman Eadric "Streona aka Acquisitive" Mercia, and Thurkytel, the son of Nafan, with him. After this, King Knute appointed Eric earl over Northumbria, as Utred was; and then went southward another way, all by west, till the whole army came, before Easter, to the ships. Meantime Edmund Etheling went to London to his father: and after Easter went King Knute with all his ships toward London; but it happened that King Ethelred died ere the ships came. He ended his days on St. George's day; having held his kingdom in much tribulation and difficulty as long as his life continued.

Anglo-Saxon Chronicle. After 23 Jun 1016. The enemy went afterward from London with their ships into the Orwell; where they went up and proceeded into Mercia, slaying and burning whatsoever they overtook, as their custom is; and, having provided themselves with meat, they drove their ships and their herds into the Medway. Then assembled King Edmund (age 26) the fourth time all the English nation, and forded over the Thames at Brentford [Map]; whence he proceeded into Kent.
