Earl Hakon, towards harvest (A.D. 963), sailed into the Bothnian Gulf
to Helsingjaland, drew his ships up there on the beach, and took the
land-ways through Helsingjaland and Jamtaland, and so eastwards round
the dividing ridge (the Kjol, or keel of the country), and down into the
Throndhjem district. Many people streamed towards him, and he fitted out
ships. When the sons of Gunhild heard of this they got on board their
ships, and sailed out of the Fjord; and Earl Hakon came to his seat at
Hlader, and remained there all winter. The sons of Gunhild, on the other
hand, occupied More; and they and the earl attacked each other in
turns, killing each other's people. Earl Hakon kept his dominions of
Throndhjem, and was there generally in the winter; but in summer he
sometimes went to Helsingjaland, where he went on board of his ships
and sailed with them down into the Baltic, and plundered there; and
sometimes he remained in Throndhjem, and kept an army on foot, so that
Gunhild's sons could get no hold northwards of Stad.
