King Sigurd sat and drank in Sigrid Saeta's house ready for battle, although people thought it would not come to an assault at all. Then came King Inge with his men down the road from the smithy shops, against the house. Arne, the king's brother-in- law, came out from the Sand-bridge, Aslak Erlendson from his own house, and Gregorius from the street where all thought the assault would be worst. King Sigurd and his men made many shots from the holes in the loft, broke down the fireplaces, and threw stones on them.
Gregorius and his men cut down the gates of the yard; and there in the port fell Einar, a son of Laxapaul, who was of Sigurd's people, together with Halvard Gunnarson, who was shot in a loft, and nobody lamented his death. They hewed down the houses, and many of King Sigurd's men left him, and surrendered for quarter. Then King Sigurd went up into a loft, and desired to be heard. He had a gilt shield, by which they knew him, but they would not listen to him, and shot arrows at him as thick as snow in a snow-shower, so that he could not stay there.
As his men had now left him, and the houses were being hewn down, he went out from thence, and with him his court-man Thord Husfreyja from Viken. They wanted to come where King Inge was to be found, and Sigurd called to his brother King Inge, and begged him to grant him life and safety; but both Thord and Sigurd were instantly killed, and Thord fell with great glory. King Sigurd was interred in the old Christ church out on the holm.
King Inge gave Gregorius the ship King Sigurd had owned. There fell many of King Sigurd's and King Inge's men, although I only name a few; but of Gregorius's men there fell four; and also some who belonged to no party, but were shot on the piers, or out in the ships. It was fought on a Friday, and fourteen days before Saint John the Baptist's day (June 10, 1155).
Two or three days after King Eystein came from the eastward with thirty ships, and had along with him his brother's son Hakon, a son of King Sigurd. Eystein did not come up to the town, but lay in Floruvagar, and good men went between to get a reconciliation made. But Gregorius wanted that they should go out against him, thinking there never would be a better opportunity; and offered to be himself the leader.
"For thou, king, shalt not go, for we have no want of men."
But many dissuaded from this course, and it came to nothing. King Eystein returned back to Viken, and King Inge to Throndhjem, and they were in a sort reconciled; but they did not meet each other.
