They spent the rest of the night then in sleep; but Finn saw a dreadful vision through his sleep that made him start three times from his bed. "What makes you start from your bed, Finn?" said Diorraing. "It was the Tuatha de Danaan I saw," said he, "taking up a quarrel against me, and making a great slaughter of the Fianna."

Now as to the Fianna, they rested at Fotharladh of Moghna that night, and they were downhearted, having no tidings of Finn. And early on the morrow two of them, Bran Beag and Bran Mor, rose up and went to Mac-an-Reith, son of the Ram, that had the gift of true knowledge, and they asked him where did Finn spend the night. And Mac-an-Reith was someway unwilling to tell them, but at the last he said it was at the house of Conan of Ceann Slieve.

The two Brans went on then to Conan's house, and Finn made them welcome; but they blamed him when they heard he was taking a wife, and none of his people with him. "Bid all the Fianna to come to the feast at the end of a month," said Conan then. So Finn and Diorraing and the two Brans went back to where the Fianna were and told them all that had happened, and they went on to Almhuin.

And when they were in the drinking-hall at Almhuin that night, they saw the son of the King of Ireland coming to where they were. "It is a pity the king's son to have come," said Finn; "for he will not be satisfied without ordering everything in the hall in his own way." "We will not take his orders," said Oisin, "but we will leave the half of the hall to him, and keep the other half ourselves."

So they did that; but it happened that in the half of the house that was given up to the King of Ireland's son, there were sitting two of the Men of Dea, Failbhe Mor and Failbhe Beag; and it is what they said, that it is because they were in that side of the hall it was given up. "It is a pity," said Failbhe Beag, "this shame and this great insult to have been put on us to-night; and it is likely Finn has a mind to do more than that again to us," he said, "for he is going to bring away the woman that is promised to the third best man of the Tuatha de Danaan, and against the will of her father and mother." And these two went away early in the morning to Fionnbhar of Magh Feabhail, and told him of the insults Finn and the Fianna of Ireland had a mind to put on the Tuatha de Danaan.

And when Fionnbhar that was king over the Tuatha de Danaan heard that, he sent out messengers through the length of Ireland to gather them all to him. And there came six good battalions to him on the edge of Loch Derg Dheirc at the end of a month; and it was the same day Conan had the wedding-feast made ready for Finn and his people.

And Finn was at Teamhair Luachra at that time, and when he heard the feast was ready, he set out to go to it. And it chanced that the most of the men he had with him at that time were of the sons of Morna. And when they were on their way, Finn said to Goll, "O Goll," he said, "I never felt any fear till now going to a feast. And there are but few of my people with me," he said; "and I know there is no good thing before me, but the Men of Dea are going to raise a quarrel against me and to kill my people." "I will defend you against anything they may do," said Goll.

They went on then to Conan's house, and there was a welcome before them, and they were brought into the drinking-hall, and Finn was put in the place beside the door, and Goll on his right and Finndeilb, of the Fair Shape, on his left, and all the rest in the places they were used to.

And as to Fionnbhar of Magh Feabhail and the Tuatha de Danaan, they put a Druid mist about themselves and went on, hidden and armed, in sixteen battalions, to the lawn before Conan's house. "It is little profit we have being here," they said then, "and Goll being with Finn against us." "Goll will not protect him this time," said Ethne, the woman-Druid, "for I will entice Finn out of the house, however well he is watched."

She went on to the house then, and took her stand before Finn outside. "Who is that before me?" she said then. "It is I myself," said Finn. "I put you under the bonds a true hero never broke," she said, "to come out to me here." When Finn heard that, he made no delay and went out to her; and for all there were so many in the house, not one of them took notice of him going, only Caoilte, and he followed him out. And at the same time the Tuatha de Danaan let out a flock of blackbirds having fiery beaks, that pitched on the breasts of all the people in the house, and burned them and destroyed them, till the young lads and the women and children of the place ran out on all sides, and the woman of the house, Conan's wife, was drowned in the river outside the dun.
