Soon after Gregorius heard that Hakon and his men were at a farm called Saurby, which lies up beside the forest. Gregorius hastened there; came in the night; and supposing that King Hakon and Sigurd would be in the largest of the houses, set fire to the buildings there.
But Hakon and his men were in the smaller house, and came forth, seeing the fire, to help their people. There Munan fell, a son of Ale Uskeynd, a brother of King Sigurd Hakon's father. Gregorius and his men killed him, because he was helping those whom they were burning within the house. Some escaped, but many were killed. Asbjorn Jalda, who had been a very great viking, escaped from the house, but was grievously wounded.
A bonde met him, and he offered the man money to let him get away; but the bonde replied, he would do what he liked best; and, adding that he had often been in fear of his life for him, he slew him. King Hakon and Sigurd escaped, but many of their people were killed. Thereafter Gregorius returned home to Konungahella. Soon after King Hakon and Sigurd went to Haldor Brynjolfson's farm of Vettaland, set fire to the house, and burnt it.
Haldor went out, and was cut down instantly with his house- men; and in all there were about twenty men killed. Sigrid, Haldor's wife, was a sister of Gregorius, and they allowed her to escape into the forest in her night-shift only; but they took with them Amunde, who was a son of Gyrd Amundason and of Gyrid Dag's daughter, and a sister's son of Gregorius, and who was then a boy about five years old.
