For about three years the two kings kept the peace, although there was little friendship between them. They both passed the fourth winter at Nidaros, and invited each other as guests, but their people were always ready for a fight. In the spring King Magnus sailed southward with his fleet, and collected men from all districts, telling the people that he wanted to take the kingly dignity from Harald and give him such a part of the country as might be suitable. Harald proceeded from Throndhjem overland to the Uplands and Viken, and, when he heard what Magnus was doing, he also collected an army. At Fyrileif in Viken a battle was fought, and Magnus, who had a much superior force, won a decisive battle. Harald's army was put to flight, and he himself barely escaped to his ships. He sailed south to Denmark, and was well received by the Danish king, Erik Emune, who gave him the province of Halland in fief. After the battle of Fyrileif (August 10, 1134), King Magnus proclaimed himself sole king of Norway. He showed great lenience toward Harald's men, and had the wounded taken care of equally with his own men. His leading men advised him to keep his army together in Viken, and remain there, in case Harald should return from the south; but he thought this was not necessary, allowed the men to return to their homes, and proceeded with his court-men to Bergen. It was not long before King Magnus had cause to regret that he had disregarded the advice of his friends. Harald had soon gathered a sufficient force to invade Norway, and, while he proceeded along the coast, a good many people joined him. He came to Bergen, where he met only nominal resistance, and King Magnus was taken prisoner. King Harald held a meeting with his counsellors, and here it was decided that Magnus should be deprived of his dominions and should no longer be called king. He was then delivered to the king's thralls, who put out both his eyes, cut off one foot, and otherwise mutilated him. Magnus, who after this was given the surname "the Blind," was brought north to Nidaros and entered the Nidarholm cloister.
