The Danish king, Nikolas, a son of Svein Ulfson, married afterwards the Queen Margaret, a daughter of King Inge, who had before been married to King Magnus Barefoot; and their sons were Nikolas and Magnus the Strong.
King Nikolas sent a message to King Sigurd the Crusader, and asked him if he would go with him with all his might and help him to the east of the Swedish dominion, Smaland, to baptize the inhabitants; for the people who dwelt there had no regard for Christianity, although some of them had allowed themselves to be baptized. At that time there were many people all around in the Swedish dominions who were heathens, and many were bad Christians; for there were some of the kings who renounced Christianity, and continued heathen sacrifices, as Blotsvein, and afterwards Eirik Arsale, had done.
King Sigurd promised to undertake this journey, and the kings appointed their meeting at Eyrarsund. King Sigurd then summoned all people in Norway to a levy, both of men and ships; and when the fleet was assembled he had about 300 ships.
King Nikolas came very early to the meeting-place, and stayed there a long time; and the bondes murmured much, and said the Northmen did not intend to come. Thereupon the Danish army dispersed, and the king went away with all his fleet.
King Sigurd came there soon afterwards, and was ill pleased; but sailed east to Svimraros, and held a House-thing, at which Sigurd spoke about King Nikolas's breach of faith, and the Northmen, on this account, determined to go marauding in his country. They first plundered a village called Tumathorp, which is not far from Lund; and then sailed east to the merchant-town of Calmar, where they plundered, as well as in Smaland, and imposed on the country a tribute of 1500 cattle for ship provision; and the people of Smaland received Christianity.
After this King Sigurd turned about with his fleet, and came back to his kingdom with many valuable articles and great booty, which he had gathered on this expedition; and this levy was called the Calmar levy. This was the summer before the eclipse. This was the only levy King Sigurd carried out as long as he was king.
