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.
