“I do not know of any well at all on this mountain,” said Finn.  “That is not so,” said Diarmuid, “for there is not nine footsteps from you the well that has the best fresh water that can be found in the world.”

Then Finn went to the well, and he took the full of his two hands of the water.  But when he was no more than half-way back, the thought of Grania came on him, and he let the water slip through his hands, and he said he was not able to bring it.  “I give my word,” said Diarmuid, “it was of your own will you let it from you.”  Then Finn went back the second time to get the water, but coming back he let it through his hands again at the thought of Grania.  And Diarmuid gave a pitiful sigh of anguish when he saw that.  “I swear by my sword and by my spear,” said Osgar, “that if you do not bring the water without any more delay, Finn, there will not leave this hill but yourself or myself.”  Finn went back the third time to the well after what Osgar said, and he brought the water to Diarmuid, but as he reached him the life went out of his body.  Then the whole company of the Fianna that were there gave three great heavy shouts, keening for Diarmuid.

And Osgar looked very fiercely at Finn, and it is what he said, that it was a greater pity Diarmuid to be dead than if he himself had died.  And the Fianna of Ireland had lost their yoke of battle by him, he said.  “Let us leave this hill,” said Finn then, “before Angus and the Tuatha de Danaan come upon us, for although we have no share in the death of Diarmuid, he would not believe the truth from us.”  “I give my word,” said Osgar, “if I had thought it was against Diarmuid you made the hunt of Beinn Gulbain, you would never have made it”

Then Finn and the Fianna went away from the hill, and Finn leading Diarmuid’s hound Mac an Chuill.  But Oisin and Osgar and Caoilte and Lugaidh’s Son turned back again and put their four cloaks over Diarmuid, and then they went after the rest of the Fianna.

And when they came to the Rath, Grania was out on the wall looking for news of Diarmuid; and she saw Finn and the Fianna of Ireland coming towards her.  Then she said:  “If Diarmuid was living, it is not led by Finn that Mac an Chuill would be coming home.”  And she was at that time heavy with child, and her strength went from her and she fell down from the wall.  And when Oisin saw the way she was he bade Finn and the others to go on from her, but she lifted up her head and she asked Finn to leave Mac an Chuill with her.  And he said he would not, and that he did not think it too much for him to inherit from Diarmuid, grandson of Duibhne.

When Oisin heard that, he snatched the hound out of Finn’s hand and gave it to Grania, and then he followed after his people.

Then when Grania was certain of Diarmuid’s death she gave out a long very pitiful cry that was heard through the whole place, and her women and her people came to her, and asked what ailed her to give a cry like that.  And she told them how Diarmuid had come to his death by the Boar of Beinn Gulbain in the hunt Finn had made.  “And there is grief in my very heart,” she said, “I not to be able to fight myself with Finn, and I would not have let him go safe out of this place.”
