After this battle (A.D. 868) King Harald subdued South More; but Vemund,
King Audbjorn's brother, still had Firdafylke. It was now late in
harvest, and King Harald's men gave him the counsel not to proceed
south-wards round Stad. Then King Harald set Earl Ragnvald over South
and North More and also Raumsdal, and he had many people about him. King
Harald returned to Throndhjem. The same winter (A.D. 869) Ragnvald went
over Eid, and southwards to the Fjord district. There he heard news of
King Vemund, and came by night to a place called Naustdal, where King
Vemund was living in guest-quarters. Earl Ragnvald surrounded the house
in which they were quartered, and burnt the king in it, together with
ninety men. The came Berdlukare to Earl Ragnvald with a complete armed
long-ship, and they both returned to More. The earl took all the ships
Vemund had, and all the goods he could get hold of. Berdlukare proceeded
north to Throndhjem to King Harald, and became his man; and dreadful
berserk he was.
