The following spring the Hat-lads went down to Viken, and raised the
king's taxes all around, and remained there long in summer. When Earl
Erling heard this, he hastened with his troops to meet them in Viken,
and fell in with them east of the Fjord, at a place called Stangar;
where they had a great battle, in which Erling was victorious. Sigurd
Agnhot, and many others of Olaf's men, fell there; but Olaf escaped by
flight, went south to Denmark, and was all winter (A.D. 1169) in Alaborg
in Jutland. The following spring Olaf fell into an illness which ended
in death, and he was buried in the Maria church; and the Danes call him
a saint.
