“This is welcome news for us,” they said; “we will indeed come, and let Fergus come as our surety, and Dubhtach, and Cormac the son of Conor.”  These then went to them, and they moved them to pass over the sea.

But at the contrivance of Conor, Fergus was pressed to join in an ale-feast, while the sons of Usnach were pledged to eat no food in Erin, until they had eaten the food of Conor.  So Fergus tarried behind with Dubhtach and Cormac; and the sons of Usnach went on, accompanied by Fiacha, Fergus’ son; until they came to the meadows around Emain.

Now at that time Eogan the son of Durthacht had come to Emain to make his peace with Conor, for they had for a long time been at enmity; and to him, and to the warmen of Conor, the charge was given that they should slay the sons of Usnach, in order that they should not come before the king.  The sons of Usnach stood upon the level part of. the meadows, and the women sat upon the ramparts of Emain.  And Eogan came with his warriors across the meadow, and the son of Fergus took his place by Naisi’s side.  And Eogan greeted them with a mighty thrust of his spear, and the spear brake Naisi’s back in sunder, and passed through it.  The son of Fergus made a spring, and he threw both arms around Naisi, and he brought him beneath himself to shelter him, while he threw himself down above him; and it was thus that Naisi was slain, through the body of the son of Fergus.  Then there began a murder throughout the meadow, so that none escaped who did not fall by the points of the spears, or the edge of the sword, and Deirdre was brought to Conor to be in his power, and her arms were bound behind her back.

Now the sureties who had remained behind, heard what had been done, even Fergus and Dubhtach, and Cormac.  And thereon they hastened forward, and they forthwith performed great deeds.  Dubhtach slew, with the one thrust of his spear, Mane a son of Conor, and Fiachna the son of Feidelm, Conor’s daughter; and Fergus struck down Traigthren, the son of Traiglethan, and his brother.  And Conor was wrath at this, and he came to the fight with them; so that upon that day three hundred of the men of Ulster fell and Dubhtach slew the women of Ulster; and, ere the day dawned, Fergus set Emain on fire.  Then they went away into exile, and betook them to the land of Connaught to find shelter with Ailill and Maev, for they knew that that royal pair would give them good entertainment.  To the men of Ulster the exiles showed no love:  three thousand stout men went with them; and for sixteen years never did they allow cries of lamentation and of fear among the Ulstermen to cease:  each night their vengeful forays caused men to quake, and to wail.

Deirdre lived on for a year in the household of Conor; and during all that time she smiled no smile of laughter; she satisfied not herself with food or with sleep, and she raised not her head from her knee.  And if any one brought before her people of mirth, she used to speak thus:
