And there rose great cries of lamentation from the armies of the World when they saw him going from them, and the Fianna of Ireland raised great shouts of joy.

And when the night was coming on, it is what Finn said:  “It is sad and gloomy the King of the World is to-night; and it is likely he will make an attack on us.  And which of you will keep watch over the harbour through the night?” he said.  “I will,” said Oisin, “with the same number that was fighting along with me to-day; for it is not too much for you to fight for the Fianna of Ireland through a day and a night,” he said.

So they went down to the harbour, and it was just at that time the King of the World was saying, “It seems to me, men of the World, that our luck of battle was not good to-day.  And let a share of you rise up now,” he said, “and make an attack on the Fianna of Ireland.”  Then there rose up the nine sons of Garb, King of the Sea of Icht, that were smiths, and sixteen hundred of their people along with them, and they all went on shore but Dolar Durba that was the eldest of them.  And the sons of Baiscne were ready for them, and they fought a great battle till the early light of the morrow.  And not one of them was left alive on either side that could hold a weapon but only Oisin and one of the sons of Garb.  And they made rushes at one another, and threw their swords out of their hands, and closed their arms about one another, and wrestled together, so that it was worth coming from the east to the west of the world to see the fight of those two.  Then the foreigner gave a sudden great fall to Oisin, to bring him into the sea, for he was a great swimmer, and he thought to get the better of him there.  And Oisin thought it would not be worthy of him to refuse any man his place of fighting.  So they went into the water together, and they were trying to drown one another till they came to the sand and the gravel of the clear sea.  And it was a torment to the heart of the Fianna, Oisin to be in that strait.  “Rise up, Fergus of the Sweet Lips,” said Finn then, “and go praise my son and encourage him.”  So Fergus went down to the edge of the sea, and he said:  “It is a good fight you are making, Oisin, and there are many to see it, for the armies of the whole world are looking at you, and the Fianna of Ireland.  And show now,” he said, “your ways and your greatness, for you never went into any place but some woman of high beauty or some king’s daughter set her love on you.”  Then Oisin’s courage increased, and anger came on him and he linked his hands behind the back of the foreigner and put him down on the sand under the sea with his face upwards, and did not let him rise till the life was gone from him.  And he brought the body to shore then, and struck off his head and brought it to the Fianna.

But there was great grief and anger on Dolar Durba, the eldest of the sons of Garb, that had stopped in the ship, and he made a great oath that he would have satisfaction for his brothers.  And he went to the High King, and he said:  “I will go alone to the strand, and I will kill a hundred men every day till I have made an end of the whole of the armies of Ireland; and if any one of your own men comes to interfere with me,” he said, “I will kill him along with them.”
