In autumn, King Halfdan proceeded to Vingulmark. One night when he was
there in guest quarters, it happened that about midnight a man came to
him who had been on the watch on horseback, and told him a war force was
come near to the house. The king instantly got up, ordered his men to
arm themselves, and went out of the house and drew them up in battle
order. At the same moment, Gandalf's sons, Hysing and Helsing, made
their appearance with a large army. There was a great battle; but
Halfdan being overpowered by the numbers of people fled to the forest,
leaving many of his men on this spot. His foster-father, Olver Spake
(the Wise), fell here. The people now came in swarms to King Halfdan,
and he advanced to seek Gandalf's sons. They met at Eid, near Lake
Oieren, and fought there. Hysing and Helsing fell, and their brother
Hake saved himself by flight. King Halfdan then took possession of the
whole of Vingulmark, and Hake fled to Alfheimar.
