And as to Goibniu, he went into the well and was healed.  But after that Octriallach, son of Indech, called to the Fomor and bade each man of them bring a stone of the stones of Drinnes and throw them into the well of Slane.  And they did that till the well was dried up, and a cairn raised over it, that is called Octriallach’s Cairn.

And it was while Goibniu was making spear-heads for the battle of Magh Tuireadh, a charge was brought against his wife.  And it was seen that it was heavy news to him, and that jealousy came on him.  And it is what he did, there was a spear-shaft in his hand when he heard the story, Nes its name was; and he sang spells over the spear-shaft, and any one that was struck with that spear afterwards, it would burn him up like fire.

And at last the day of the great battle came, and the Fomor came out of their camp and stood in strong ranks.  And there was not a leader or a fighting man of them was without good armour to his skin, and a helmet on his head, a broad spear in his right hand, a heavy sword in his belt, a strong shield on his shoulder.  And to attack the army of the Fomor that day was to strike the head against a rock, or to go up fighting against a fire.

And the Men of Dea rose up and left Lugh and his nine comrades keeping him, and they went on to the battle; and Midhir was with them, and Bodb Dearg and Diancecht.  And Badb and Macha and the Morrigu called out that they would go along with them.

And it was a hard battle was fought, and for a while it was going against the Tuatha de Danaan; and Nuada of the Silver Hand, their King, and Macha, daughter of Emmass, fell by Balor, King of the Fomor.  And Cass-mail fell by Octriallach, and the Dagda got a dreadful wound from a casting spear that was thrown by Ceithlenn, wife of Balor.

But when the battle was going on, Lugh broke away from those that were keeping him, and rushed out to the front of the Men of Dea.  And then there was a fierce battle fought, and Lugh was heartening the men of Ireland to fight well, the way they would not be in bonds any longer.  For it was better for them, he said, to die protecting their own country than to live under bonds and under tribute any longer.  And he sang a song of courage to them, and the hosts gave a great shout as they went into battle, and then they met together, and each of them began to attack the other.

And there was great slaughter, and laying low in graves, and many comely men fell there in the stall of death.  Pride and shame were there side by side, and hardness and red anger, and there was red blood on the white skin of young fighting men.  And the dashing of spear against shield, and sword against sword, and the shouting of the fighters, and the whistling of casting spears and the rattling of scabbards was like harsh thunder through the battle.  And many slipped in the blood that was under their feet, and they fell, striking their heads one against another; and the river carried away bodies of friends and enemies together.
