In 1153 King Eystein made a cruise to the Orkneys. Some time after his return there was a quarrel between him and King Sigurd, because the latter had killed two of Eystein's court-men. A conference to settle this affair was arranged in the winter (1154-55) in the Uplands. They not only settled their difficulty, but privately arranged for a meeting of the three kings in Bergen next summer. It was said that their plan was to depose King Inge and give him two or three estates and a certain income, as he had not health to be a king. Their plan might possibly have succeeded if it had not been for King Inge's faithful man, Gregorius Dagson, who was then Inge's guardian and adviser. He made preparations for the meeting, and when Sigurd arrived in Bergen, King Inge had a superior force. After some hostile acts, King Sigurd was attacked in his lodgings by Gregorius Dagson and slain, June 10, 1155. Two or three days after King Eystein arrived from the east with thirty ships. He had along with him his brother's seven year old son Haakon, a son of King Sigurd. When he heard what had happened in Bergen, Eystein did not come up to the town, but anchored at Florevaag, while a reconciliation between the brothers was attempted. The result was that King Eystein returned to Viken and King Inge to Throndhjem, and they were in a way reconciled; but they did not meet each other. About a year later, after several quarrels and provoking incidents, the two brothers met with hostile fleets at Fors, Ranrike, and made ready for battle. So many of King Eystein's ships left him, however, and joined King Inge that Eystein had no choice but flight. He was captured by his brother-in-law, Simon Skalp, who murdered him after having allowed him to hear mass (August 21, 1157). King Eystein was buried in Fors Church.
