 The saga then relates how the Earl Maddaðr gave Sveinn guides, and how Sveinn travelled through the interior of the country — over mountains, and through woods, away from inhabited areas — until he came upon Strath Helmsdale, near where Ölvir and Frakökk lived. Williams stated that since the saga records that Sveinn approached the area by land, the site of Ölvir and Frakökk's estate was probably located somewhere in the dale of Helmsdale — not where the modern village is situated on the coast. Williams also noted that this area was quite remote from Orkney, and that it may have been outside of the control of the earldom. The saga states that Ölvir and Frakökk had spies on the lookout; however, because of the route taken by Sveinn, they were unaware of his presence until Svienn occupied a certain slope behind their homestead. The saga states that Ölvir and sixty of his men confronted Sveinn, although Þormóður Torfason's account of the incident gives forty. After a short clash, the saga states that, Ölvir's men soon gave way, and many were killed in the ensuing rout. Ölvir survived the clash, and fled up Helmsdale river. Meanwhile, Sveinn and his men continued on towards the houses. The area was plundered, and the houses were burnt to the ground with their inmates still inside — and in this way Frakökk perished. The saga states that Sveinn and his men committed many ravages in Sutherland before returning home. Upon reaching the river, Ölvir fled through the mountains, and is last heard making for the Suðreyjar; he is not mentioned again within the Orkneyinga saga. Later on within the saga, another of Frakökk's grandsons, Þórbjörn 'Clerk', who is a brother-in-law and close friend of Sveinn, has two of Sveinn's men killed for their part in the burning.
