King Olaf was in Svithjod in spring (A.D. 1030), and had sent spies from
thence to Norway. All accounts from that quarter agreed that there was
no safety for him if he went there, and the people who came from the
north dissuaded him much from penetrating into the country. But he had
firmly resolved within himself, as before stated, to go into Norway; and
he asked King Onund what strength King Onund would give him to conquer
his kingdom. King Onund replied, that the Swedes were little inclined
to make an expedition against Norway. "We know," says he, "that the
Northmen are rough and warlike, and it is dangerous to carry hostility
to their doors, but I will not be slow in telling thee what aid I can
give. I will give thee 400 chosen men from my court-men, active and
warlike, and well equipt for battle; and moreover will give thee leave
to go through my country, and gather to thyself as many men as thou
canst get to follow thee." King Olaf accepted this offer, and got ready
for his march. Queen Astrid, and Ulfhild the king's daughter, remained
behind in Svithjod.
