“ In the first year of his reign Edmund had trouble with Olaf or Anlaf Sihtricsson, called Cuaran. The latter had just crossed from Ireland and had been chosen king by the Northumbrians, who threw off their allegiance to Edmund. Anlaf took York, besieged Northampton and destroyed Tamworth, but was met by Edmund at Leicester. The enemy escaped, but a peaceful settlement was made by the good offices of Odo of Canterbury and Wulfstan of York. Simeon of Durham states that a division of the kingdom was now made, whereby Edmund took England south of Watling Street and Anlaf the rest. ”
