The same winter (A.D. 1043), in which Svein Ulfson was raised to the government of the whole Danish dominions, and had made friends of a great number of the principal chiefs in Denmark, and obtained the affections of the people, he assumed by the advice of many of the chiefs the title of king.
But when in the spring thereafter he heard that King Magnus had come from the north with a great army, Svein went over to Scania, from thence up to Gautland, and so on to Svithjod to his relation, King Emund, where he remained all summer, and sent spies out to Denmark, to inquire about the king's proceedings and the number of his men.
Now when Svein heard that King Magnus had let a great part of his army go away, and also that he was south in Jutland, he rode from Svithjod with a great body of peopie which the Swedish king had given him. When Svein came to Scania the people of that country received him well, treated him as their king, and men joined him in crowds. He then went on to Seeland, where he was also well received, and the whole country joined him. He then went to Fyen, and laid all the islands under his power; and as the people also joined him, he collected a great army and many ships of war.
