Earl Sigurd went in harvest into Stjoradal to guest-quarters, and from thence went to Oglo to a feast. The earl usually had many people about him, for he did not trust the king; but now, after friendly messages had passed between the king and him, he had no great following of people with him.
Then Grjotgard sent word to the king that he could never expect a better opportunity to fall upon Earl Sigurd; and immediately, that very evening, Harald and Erling sailed into Throndhjem fjord with several ships and many people. They sailed all night by starlight, and Grjotgard came out to meet them.
Late in the night they came to Oglo, where Earl Sigurd was at the feast, and set fire to the house; and burnt the house, the earl, and all his men. As soon as it was daylight, they set out through the fjord, and south to More, where they remained a long time.
