Two days after the jarls came there was an army approaching at the head of the army was harkon who after arriving got off his horse and saw the square and one man in it and walked to it after entering the square took of his clothes and took his ax and shield as he saw his opponent having only a sword and shield and said 'your Olaf?' To which the man nodded he continued 'today is your final day of living I will kill you and take your lands for myself,' Olaf smiled and said 'your time has passed harkon I am the future I will lead our people to the golden age but after I have killed you I'll give you a proper Viking burial,' it looked like both men had said what they wanted to say now all there was left was action.
Both men fight without armor, using only a shield and one weapon: a sword for Olaf and an ax for Harkon. Things do not look good for Olaf as he's knocked to the ground defenseless, but when Harkon raises his ax to deal the final stroke, Olaf grabs a nearby shard from his splintered shield and stabs Harkon above the knee. In Harkon's moment of pain, Olaf reaches for his sword and in one fell movement, slices Harkon Achilles heels open. Harkon falls forward as Olaf makes another slice at his neck. Respectful of his opponent as a warrior, Olaf places the battleax in the dying harkon's right hand and sends him on his way to Valhalla.
After the fight Olaf turned and looked at the men of Oslo who all after seeing their jarl defeated knelt down to Olaf in respect for the great warrior and olaf said 'Harkon has fought as a warrior and will be buried as one, he then continued I will go on a raid in the next spring and together with all the jarls who have agreed to join me,' the others walked to stand near him, he looked at the men of Oslo and said 'as well as you all who are under my rule and protection,' after hearing this the Oslo Vikings were greetful for Olaf's kindness, Olaf looked at Eric and called for him,when he came 'he said eric you have served me well and for that I Ofer you to look after Oslo in my stead,' hearing this eric knelt down and said 'my lord I will serve you well,' olaf smiled and said 'I know you will and in spring we will raid Bremen a large city in east frankia this will be a great raid with riches and great battle for all those who join me!' and there was massive cheering as the Vikings looked forward to the raid, Olof went back to the camp with his son and their other jarls sweyn said 'Olaf now your the most powerful lord in all of Norway I am curious as to when you will make yourself king?' After hearing this they all look at him and olaf who heard this siad 'I haven't thought of it,we can all talk about after the raid of Bremen am sure things will be different after that.' After that they all said their farewells and went back to their homes and will meet up back in kaupang in spring for their next raid.
