Then did the son of Concobar strike with his enchanted weapons, and all the waves of Erin thundered at the stroke. And a great warrior, hearing the thunder, came riding across the plain, and in his hand he held a magic sword with blade of blue. Coming upon the fighting men, he rushed at the son of Fergus from behind, and thrust the blue blade through his heart. ‘I would that mine enemy had fought me fair,’ said the dying man.

‘Who art thou?’ asked the stranger.

And the son of Fergus told his name, and of that which had come to pass in the House of the Red Branch.

Then answered the stranger, ‘I shall not depart hence, no, not until the son of Concobar be slain in the dust’; and thereupon he rushed upon the King’s son, and with one stroke of the blue blade severed his head from his body. So he departed, and soon the son of Fergus also lay dead.

And now the Ulstermen surrounded the House of the Red Branch and set fire to its walls. But Ardan came forth, and put out the fire, and slew three hundred men, and after he had gone in, then came Ailne forth, and slew a countless multitude beside.

A glimmering ray of dim grey light now broke, and spread over the forms of dead and dying men.

It was at that hour that Nathos kissed Deirdre and went forth from the House. And there was not a man but quailed as the hero rushed upon the Ultonians and slew a thousand men.

When Concobar heard this, he sent for that Wise Man who in the house of Felim the Harper had foretold the sorrow that would come upon his realm.

And when the old man had come, Concobar said, ‘I swear that I mean no harm unto the sons of Usna, yet will they slay every Ultonian in the land. Therefore I would that thou wouldst help me by thy magic power.’

And the Wise Man believed the words of Concobar, and he caused a hedge of spears to encircle the burning House. And as the flames rose higher the sons of Usna came forth with Deirdre the Star-eyed. And around her they placed their shields, and they cleft a way through the Hedge of Spears and came safely to the plain beyond.
