Magnus the Blind then went to Denmark to King Eirik Eimune, where he was well received. He offered the king to follow him if he would invade Norway with a Danish army, and subdue the country; saying, that if he came to Norway with his army, no man in Norway would venture to throw a spear against him.
The king allowed himself to be moved by Magnus's persuasions, ordered a levy, and went north to Norway with 200 ships; and Magnus and his men were with him on this expedition. When they came to Viken, they proceeded peacefully and gently on the east side of the fjord; but when the fleet came westward to Tunsberg, a great number of King Inge's lendermen came against them.
Their leader was Vatnorm Dagson, a brother of Gregorius. The Danes could not land to get water without many of them being killed; and therefore they went in through the fjord to Oslo, where Thjostolf Alason opposed them.
It is told that some people wanted to carry the holy Halvard's coffin out of the town in the evening when the fleet was first observed, and as many as could took hold of it; but the coffin became so heavy that they could not carry it over the church floor. The morning after, however, when they saw the fleet sailing in past the Hofud Isle, four men carried the coffin out of the town, and Thjostolf and all the townspeople followed it.
