Then the host of the Sidhe went out to the battle, and the armies attacked one another with wide green spears and with little casting spears, and with great stones; and the fight went on from the rising of the day till midday.  And then Caoilte and Lir met with one another, and they made a very fierce fight, and at the last Lir of Sidhe Fionnachaidh fell by the hand of Caoilte.

Then the two good champions Dubh and Donn, sons of Eirrge, determined to go on with the battle, and it is how they fought, Dubh in the front of the whole army, and Donn behind all, guarding the rear.  But Derg saw that, and he put his finger into the thong of his spear and made a cast at the one that was nearest him, and it broke his back and went on into the body of the other, so that the one cast made an end of the two.  And that ended the battle, and all that was left of the great army of Lir went wearing away to the north.  And there was great rejoicing in the hill at Ess Ruadh, and Ilbrec took the spoils of the beaten army for his people, and to Caoilte he gave the enchanted spear of Fiacha, together with nine rich cloaks and nine long swords with hilts and guards of gold, and nine hounds for hunting.  And they said farewell to one another, and Caoilte left his blessing to the people of the hill, and he brought their thanks with him.  And as hard as the battle had been, it was harder again for Derg to part from his comrade, and the day he was parted from Finn and from all the Fianna was no sadder to him than this day.

It was a long time after that Caoilte went again to the hill of Ilbrec at Ess Ruadh, and this is the way it happened.

It was in a battle at Beinn Edair in the east that Mane, son of the King of Lochlann, made a cast at him in the middle of the battle with a deadly spear.  And he heard the whistling of the spear, and it rushing to him; and he lifted his shield to protect his head and his body, but that did not save him, for it struck into his thigh, and left its poison in it, so that he had to go in search of healing.  And it is where he went, to the hill of the Sidhe at Ess Ruadh, to ask help of Bebind, daughter of Elcmar of Brugh na Boinne, that had the drink of healing of the Tuatha de Danaan, and all that was left of the ale of Goibniu that she used to be giving out to them.

And Caoilte called to Cascorach the Musician, son of Caincenn, and bade him bring his harp and come along with him.  And they stopped for a night in the hill of the Sidhe of Druim Nemed in Luigne of Connacht, and from that they went forward by Ess Dara, the Fall of the Oaks, and Druim Dearg na Feinne, the Red Ridge of the Fianna, and Ath Daim Glas, the Ford of the Grey Stag, and to Beinn Gulbain, and northward into the plain of Ceitne, where the Men of Dea used to pay their tribute to the Fomor; and up to the Footstep of Ess Ruadh, and the High Place of the Boys, where the boys of the Tuatha de Danaan used to be playing their hurling.  And Aedh of Ess Ruadh and Ilbrec
