And when spring came, and men made ready to go their several ways,
then did Hallvard and his brother again urge their request that they
might go and take Thorolf's life. So the king gave them leave.
'And I know,' he said, 'ye will bring me his head and many costly things
withal when ye come back;
yet some do guess that if ye sail north ye will both sail and row south.'
They made them ready with all speed, taking two ships and two hundred men;
and when they were ready they sailed with a north-east wind out of the firth,
but that is a head-wind for those coasting northward.
