The Chronicle of The Kings of Norway
Part 204 - Of The Lendermen In Norway
Now we must relate what, in the meantime, was going on in Norway. Thorer Hund, in these two winters (A.D. 1029-1030), had made a Lapland journey, and each winter had been a long time on the mountains, and had gathered to himself great wealth by trading in various wares with the Laplanders.
He had twelve large coats of reindeer-skin made for him, with so much Lapland witchcraft that no weapon could cut or pierce them any more than if they were armour of ring-mail, nor so much. The spring thereafter Thorer rigged a long-ship which belonged to him, and manned it with his house-servants. He summoned the bondes, demanded a levy from the most northern Thing district, collected in this way a great many people, and proceeded with this force southwards.
Harek of Thjotta had also collected a great number of people; and in this expedition many people of consequence took a part, although these two were the most distinguished. They made it known publicly that with this war-force they were going against King Olaf, to defend the country against him, in case he should come from the eastward.
