Now as Jon and his troop had broken the one wing of King Inge's array, many of those who were nearest to him fled, by which the whole array was dispersed, and fell into disorder. But Hakon and his men went briskly forwards; and now it was near daybreak. An assault was made against King Inge's banner, and in this conflict King Inge fell; but his brother Orm continued the battle, while many of the army fled up into the town.
Twice Orm went to the town after the king's fall to encourage the people, and both times returned, and went out again upon the ice to continue the battle. Hakon's men attacked the wing of the array which Simon Skalp led; and in that assault fell of King Inge's men his brother-in-law, Gudbrand Skafhogson. Simon Skalp and Halvard Hikre went against each other with their troops, and fought while they drew aside past Thraelaberg; and in this conflict both Simon and Halvard fell.
Orm, the king's brother, gained great reputation in this battle; but he at last fled. Orm the winter before had been contracted with Ragna, a daughter of Nikolas Mase, who had been married before to King Eystein Haraldson; and the wedding was fixed for the Sunday after Saint Blasius's mass, which was on a Friday.
Orm fled east to Svithjod, where his brother Magnus was then king; and their brother Ragnvald was an earl there at that time. They were the sons of Queen Ingerid and Henrik Halte, who was a son of the Danish king Svein Sveinson. The princess Kristin took care of King Inge's body, which was laid on the stone wall of Halvard's church, on the south side without the choir.
He had then been king for twenty-three years (A.D. 1137-1161). In this battle many fell on both sides, but principally of King Inge's men. Of King Hakon's people fell Arne Frirekson. Hakon's men took all the feast and victuals prepared for the wedding, and a great booty besides.
