Now those kings of Sogn, the brethren of Ingibiorg, heard these tidings, how that Frithiof had gotten a king's rule in Ringrealm, and had wedded Ingibiorg their sister. Then says Helgi to Halfdan, his brother, that unheard of it was, and a deed over-bold, that a mere hersir's son should have her to wife: and so thereat they gather together a mighty army, and go their ways therewith to Ringrealm, with the mind to slay Frithiof, and lay all his realm under them.

But when Frithiof was ware of this, he gathered folk, and spake to the queen moreover: "New war is come upon our realm; and now, in whatso wise the dealings go, fain am I that thy ways to me grow no colder."

She said: "In such wise have matters gone that I must needs let thee be the highest."

Now was Biorn come from the east to help Frithiof; so they fared to the fight, and it befell, as ever erst, that Frithiof was the foremost in the peril: King Helgi and he came to handy-blows, and there he slew King Helgi.

Then bade Frithiof raise up the Shield of Peace, and the battle was stayed; and therewith he cried to King Halfdan: "Two choices are in thine hands now, either that thou give up all to my will, or else gettest thou thy bane like thy brother; for now may men see that mine is the better part."

So Halfdan chose to lay himself and his realm under Frithiof's sway; and so now Frithiof became ruler over Sogn-folk, and Halfdan was to be Hersir in Sogn and pay Frithiof tribute, while Frithiof ruled Ringrealm. So Frithiof had the name of King of Sogn-folk from the time that he gave up Ringrealm to the sons of King Ring, and thereafter he won Hordaland also. He and Ingibiorg had two sons, called Gunnthiof and Hunthiof, men of might, both of them.

And so here endeth the story of Frithiof the Bold.
