Note 243 — Chapter II · OF AMUNDI AND THORKEL.
Gilbert Goudie translation
Eyvind Urarhorn was a Lenderman (or Baron) of King Olaf Haraldson. He had gone to Ireland to King Conchobhar previous to Einar’s expedition, and had assisted the Irish against the Orkneymen. The Saga of Olaf Haraldson says that Earl Einar was much displeased with the Northmen who had been in the battle on the side of the Irish king, and seized this opportunity of wreaking his vengeance on Eyvind, their leader.
