The following spring (A.D. 869) King Harald went southwards with his
fleet along the coast, and subdued Firdafylke. Then he sailed eastward
along the land until he came to Vik; but he left Earl Hakon Grjotgardson
behind, and set him over the Fjord district. Earl Hakon sent word to
Earl Atle Mjove that he should leave Sogn district, and be earl over
Gaular district, as he had been before, alleging that King Harald had
given Sogn district to him. Earl Atle sent word that he would keep both
Sogn district and Gaular district, until he met King Harald. The two
earls quarreled about this so long, that both gathered troops. They met
at Fialar, in Stavanger fiord, and had a great battle, in which Earl
Hakon fell, and Earl Atle got a mortal wound, and his men carried him to
the island of Atley, where he died. So says Eyvind Skaldaspiller:--
"He who stood a rooted oak,
Unshaken by the swordsman's stroke,
Amidst the whiz of arrows slain,
Has fallen upon Fjalar's plain.
There, by the ocean's rocky shore,
The waves are stained with the red gore
Of stout Earl Hakon Grjotgard's son,
And of brave warriors many a one."
