The summer after (A.D. 1158) Hakon came with his men, and proceeded to Konungahella with a numerous and handsome troop. Gregorius was then in the town, and summoned the bondes and townspeople to a great Thing, at which he desired their aid; but he thought the people did not hear him with much favour, so he did not much trust them. Gregorius set off with two ships to Viken, and was very much cast down.
He expected to meet King Inge there, having heard he was coming with a great army to Viken. Now when Gregorius had come but a short way north he met Simon Skalp, Haldor Brynjolfson, and Gyrd Amundason, King Inge's foster-brothers. Gregorius was much delighted at this meeting, and turned back with them, being all in one body, with eleven ships.
As they were rowing up to Konungahella, Hakon, with his followers, was holding a Thing without the town, and saw their approach; and Sigurd of Reyr said,
"Gregorius must be fey to be throwing himself with so few men into our hands."
Gregorius landed opposite the town to wait for King Inge, for he was expected, but he did not come. King Hakon put himself in order in the town, and appointed Thorliot Skaufaskalle, who was a viking and a robber, to be captain of the men in the merchant ships that were afloat in the river; and King Hakon and Sigurd were within the town, and drew up the men on the piers, for all the townspeople had submitted to King Hakon.
