The reinforcements brought by Rollo and Bjorn don't suffice to chase Borg from Kattegat, but he's drawn out by destroying the winter food supply, performed at night by Ragnar and Bjorn. The battle is undecided, but the earl retreats to Gotland. In Wessex, king Ecbert lets Athelstan advice him about pagan law and justice. Initially unable to attend mass sincerely, the apostate seeks a sign to regain his faith. Seeing how well eager warrior-apprentice Bjorn get on with his half-brothers, Ragnar invites him and his mother to stay, but she decides to return to her present husband alone, the the princess's grateful joy.
