Gunhild's sons levied a great army in Viken (A.D. 963), and sailed along the land northwards, collecting people and ships on the way out of every district. They then made known their intent, to proceed northwards with their army against Earl Hakon in Throndhjem. When Earl Hakon heard this news, he also collected men, and fitted out ships; and when he heard what an overwhelming force Gunhild's sons had with them, he steered south with his fleet to More, pillaging wherever he came, and killing many people. He then sent the whole of the bonde army back to Throndhjem; but he himself, with his men-at-arms, proceeded by both the districts of More and Raumsdal, and had his spies out to the south of Stad to spy the army of Gunhild's sons; and when he heard they were come into the Fjords, and were waiting for a fair wind to sail northwards round Stad, Earl Hakon set out to sea from the north side of Stad, so far that his sails could not be seen from the land, and then sailed eastward on a line with the coast, and came to Denmark, from whence he sailed into the Baltic, and pillaged there during the summer. Gunhild's sons conducted their army north to Throndhjem, and remained there the whole summer collecting the scat and duties. But when summer was advanced they left Sigurd Slefa and Gudron behind; and the other brothers returned eastward with the levied army they had taken up in summer.
