Epilogue As the dukes’ followers besieged the fortress, Birger came to check on his prisoners one last time. Then he locked the door to their miserable prison, threw the key in the river and fled by sea to Stegeborg. Then Nyköping was under siege,And that made the king worried.When the king saw this,He went up to the towerAnd thought about his evil deeds,Which he had conceivedOn the advice of unwise men; But though they did help somewhat,He needed little convincing– it is easy to advise those with evil intent. Then he locked the tower carefully,and disgraced himself greatlyby casting the key into the river,so that it could not be found.Then he left for Stegeborg.
