On the fourth day Ferdia knew the contest would be decided, and he armed himself with especial care. Next his skin was a tunic of striped silk bordered with golden spangles, and over that hung an apron of brown leather. Upon his belly he laid a flat stone, large as a millstone, and over that a strong, deep apron of iron, for he dreaded that Cuchulain would use the Gae Bolg that day. And he put on his head his crested helmet studded with carbuncle and inlaid with enamels, and girt on his golden-hilted sword, and on his left arm hung his broad shield with its fifty bosses of bronze. Thus he stood by the Ford, and as he waited he tossed up his weapons and caught them again and did many wonderful feats, playing with his mighty weapons as a juggler plays with apples; and Cuchulain, watching him, said to Laeg, his driver: “If I give ground to-day, do thou reproach and mock me and spur me on to valour, and praise and hearten me if I do well, for I shall have need of all my courage.”
“O Ferdia,” said Cuchulain when they met, “what shall be our weapons to-day?” “It is thy choice to-day,” said Ferdia. “Then let it be all or any,” said Cuchulain, and Ferdia was cast down at hearing this, but he said, “So be it,” and thereupon the fight began. Till midday they fought with spears, and none could gain any advantage over the other. Then Cuchulain drew his sword and sought to smite Ferdia over the rim of his shield; but the giant Firbolg flung him off. Thrice Cuchulain leaped high into the air, seeking to strike Ferdia over his shield, but each time as he descended Ferdia caught him upon the shield and flung him off like a little child into the Ford. And Laeg mocked him, crying: “He casts thee off as a river flings its foam, he grinds thee as a millstone grinds a corn of wheat; thou elf, never call thyself a warrior.”
Then at last Cuchulain’s frenzy came upon him, and he dilated giant-like, till he overtopped Ferdia, and the hero-light blazed about his head. In close contact the two were interlocked, whirling and trampling, while the demons and goblins and unearthly things of the glens screamed from the edges of their swords, and the waters of the Ford recoiled in terror from them, so that for a while they fought on dry land in the midst of the riverbed. And now Ferdia found Cuchulain a moment off his guard, and smote him with the edge of the sword, and it sank deep into his flesh, and all the river ran red with his blood. And he pressed Cuchulain sorely after that, hewing and thrusting so that Cuchulain could endure it no longer, and he shouted to Laeg to fling him the Gae Bolg. When Ferdia heard that he lowered his shield to guard himself from below, and Cuchulain drove his spear over the rim of the shield and through his breastplate into his chest. And Ferdia raised his shield again, but in that moment Cuchulain seized the Gae Bolg in his toes and drove it upward against Ferdia, and it pierced through the iron apron and burst in three the millstone that guarded him, and deep into his body it passed, so that every crevice and cranny of him was filled with its barbs. “’Tis enough,” cried Ferdia; “I have my death of that. It is an ill deed that I fall by thy hand, O Cuchulain.” Cuchulain seized him as he fell, and carried him northward across the Ford, that he might die on the further side of it, and not on the side of the men of Erin. Then he laid him down, and a faintness seized Cuchulain, and he was falling, when Laeg cried: “Rise up, Cuchulain, for the host of Erin will be upon us. No single combat will they give after Ferdia has fallen.” But Cuchulain said: “Why should I rise again, O my servant, now he that lieth here has fallen by my hand?” and he fell in a swoon like death. And the host of Maev with tumult and rejoicing, with tossing of spears and shouting of war-songs, poured across the border into Ulster.
