In the spring King Haakon started southward with quite a fleet. By a stratagem Erling succeeded in surprising him, when his forces were divided, at Sekken, in Raumsdal, where a battle was fought. Haakon was defeated, and the young king himself was killed (1162). Haakon's body was buried in Raumsdal; but afterward his brother, King Sverre, had the body removed to Nidaros and laid in the stone wall in Christ Church south of the choir. CHAPTER XXVII _Magnus Erlingson (1162-1184)--The Birchlegs_ After the battle of Sekken, Erling Skakke proceeded with King Magnus and the whole army up to Nidaros, where the Thing was convened, and Magnus was proclaimed king of all Norway. They remained there but a short time, however, for Erling did not put great faith in the Throndhjem people. Erling returned with his son to Bergen, and later in the fall went to Tunsberg, where he intended to stay during the winter. Some of the late King Haakon's chiefs, who had not been present at the battle, among them Earl Sigurd of Reyr, refused to acknowledge King Magnus. They left their ships in Raumsdal and went over to Uplands, where they found many adherents. They chose for their king a young son of King Sigurd Mund, named Sigurd Markusfostre (_i.e._, foster-son of Markus), who had been brought up by Markus of Skog, a friend and relative of Earl Sigurd. Quite an army was collected, but as the territory they held was small, their foraging became burdensome to the people, and there was considerable dissatisfaction. Erling Skakke took advantage of this, and when finally a battle was fought at Ree, near Tunsberg, he easily defeated Sigurd's adherents. Earl Sigurd fell in the battle (February, 1163). Sigurd Markusfostre and his foster-father were captured and killed in the fall of the same year.
