During his reign, Huyrwil, the lord of Oland, made a league with the Danes and attacked Norway.

No small fame was added to his deeds by the defeat of the amazon Rusila, who aspired with military ardour to prowess in battle: but he gained manly glory over a female foe.

Also he took into his alliance, on account of their deeds of prowess, her five partners, the children of Finn, named Brodd, Bild, Bug, Fanning, and Gunholm.
Their confederacy emboldened him to break the treaty which he made with the Danes; and the treachery of the violation made it all the more injurious, for the Danes could not believe that he could turn so suddenly from a friend into an enemy; so easily can some veer from goodwill into hate.

I suppose that this man inaugurated the morals of our own day, for we do not account lying and treachery as sinful and sordid.

When Huyrwil attacked the southern side of Zealand, Fridleif assailed him in the harbour which was afterwards called by Huyrwil's name.
