So it came to pass that Erik, in his desire to repair the losses incurred in flight, attacked the districts subject to Halfdan.

Even Denmark he did not exempt from this harsh treatment; for he thought it a most worthy deed to assail the country of the man who had caused him to be driven from his own.

And so, being more anxious to inflict injury than to repel it, he set Sweden free from the arms of the enemy.

When Halfdan heard that his brother Harald had been beaten by Erik in three battles, and slain in the fourth, he was afraid of losing his empire; he had to quit the land of the Swedes and go back to his own country.

Thus Erik regained the kingdom of Sweden all the more quickly, that he quitted it so lightly.
