It is told that Earl Hakon Grjotgardson came to King Harald from Yrjar,
and brought a great crowd of men to his service. Then King Harald went
into Gaulardal, and had a great battle, in which he slew two kings, and
conquered their dominions; and these were Gaulardal district and Strind
district. He gave Earl Hakon Strind district to rule over as earl. King
Harald then proceeded to Stjoradal, and had a third battle, in which
he gained the victory, and took that district also. There upon the
Throndhjem people assembled, and four kings met together with their
troops. The one ruled over Veradal, the second over Skaun, third over
the Sparbyggja district, and the fourth over Eyin Idre (Inderoen); and
this latter had also Eyna district. These four kings marched with their
men against King Harald, but he won the battle; and some of these kings
fell, and some fled. In all, King Harald fought at the least eight
battles, and slew eight kings, in the Throndhjem district, and laid the
whole of it under him.
