The Death of Cú Chulainn
A PROPHECY OF VENGEANCE
Throughout his life as Ulster’s champion, Cú Chulainn faced many warriors, defeating all who challenged him.
Among them was a powerful sorcerer named Calatín, whom Cú Chulainn struck down in battle. Unbeknownst to him, Calatín’s wife was pregnant. She later gave birth to six children—three boys and three girls—and raised them in the arts of druidry and sorcery, filling their hearts with a single purpose: to avenge their father’s death.
Years passed, and Cú Chulainn lived on, unaware of the danger growing in the shadows. When the children of Calatín came of age, they set out to take their revenge.
A KING’S DESPERATION
King Conchobar mac Nessa knew that if Ulster lost Cú Chulainn, their greatest warrior, Emain Macha would fall, and his reign would come to an end.
To protect him, Conchobar summoned Cú Chulainn to Emain Macha, keeping him distracted with feasts, games, and sports. He told him nothing of the looming threat, for he knew that Cú Chulainn would never cower from a fight.
Meanwhile, the three sons and three daughters of Calatín arrived at Emain Macha and began weaving their sorcery.
Using their magic, they conjured the sounds of war—the clash of steel on steel, the thunder of marching feet, the screams of the dying.
The terrible noise filled the city, but Conchobar was prepared.
He gathered his warriors and held a great feast, filling the halls with singing, storytelling, and laughter. For three days and three nights, the joyous revelry drowned out the phantom war outside, keeping Cú Chulainn unaware of the deception.
But the magic did not fade, and Conchobar knew he could not hold him back forever.
He sent Cú Chulainn away to Glenn na Marbh—the Valley of Death, a place where no sound could enter. There, he would hear nothing of the battle cries meant to lure him out.
A FINAL BETRAYAL
When their sorcery failed, the children of Calatín knew they needed another plan.
One of the daughters disguised herself as Niamh, a dear friend of Cú Chulainn, and entered Glenn na Marbh.
She told him he was needed in battle, urging him to take up his weapons and fight for Ulster.
Without hesitation, Cú Chulainn leapt into action, racing to hitch his horse, the Grey of Macha, to his chariot.
But for the first time since they had fought together, the Grey of Macha shied away, showing him the whites of her eyes.
He tried again—and again, she stepped back.
On his third attempt, he berated her, demanding she obey him.
At last, the horse stepped into the traces—but as she did, she wept great tears of blood.
Cú Chulainn called for his charioteer, Láeg, who stepped up beside him.
Then came his mother, Deichtire, offering him a farewell cup of wine, giving him her blessing for the coming battle.
But as he lifted the cup to his lips, the wine turned to blood.
Shocked, he threw it away, and Deichtire refilled it—but again, it turned to blood.
On the third attempt, the same dark omen appeared, and Cú Chulainn could not drink.
THE PROPHECY OF THE WASHER AT THE FORD
As he rode toward battle, Cú Chulainn crossed a river, where he saw an old woman washing bloodied clothes in the water.
When he greeted her, she looked up and said:
“I am washing the armour of Cú Chulainn, who is going to die today.”
Cú Chulainn drove on, but the weight of her words hung over him.
Further along the road, he came upon three hags roasting a hound on a spit.
They invited him to share their meal, but he hesitated—he was under a geis never to eat the flesh of a hound, his namesake.
He tried to refuse, but the hags mocked him, saying he had grown too proud to eat with common folk.
Bound by his honour as a warrior, he could not turn down their hospitality.
Taking the meat with his left hand, he ate.
The moment it touched his lips, all the strength drained from his left arm.
When a piece of meat dropped onto his thigh, his left leg weakened as well.
Cú Chulainn knew he had broken his geis—and in doing so, he had lost half his strength.
The hags vanished—they had been the Morrígan, the goddess of war, taking revenge for the time Cú Chulainn had rejected her love.
THE FINAL BATTLE
As Cú Chulainn rode on, he encountered the three sons of Calatín, alongside Lugaid mac Con Roí, son of his old enemy.
It had been foretold that Cú Chulainn’s first three spear throws in battle would kill three kings.
The sons of Calatín sought to claim those spears for themselves.
The first son demanded a spear, threatening to satirise Ulster if he refused.
“Never let it be said that I am not a generous man,” Cú Chulainn replied—and he hurled the spear through the first son’s skull.
Lugaid pulled the spear from the corpse and threw it back, missing Cú Chulainn but striking Láeg in the stomach, killing his loyal charioteer.
The second son demanded a spear.
“Ulster will not lose its honour because of its champion,” Cú Chulainn said—and he threw his spear through the second son’s head.
Lugaid hurled it back, killing the Grey of Macha.
Cú Chulainn fell to his knees, mourning his great horse.
The third son stepped forward and demanded a spear.
“Never let it be said I brought dishonour upon my family,” Cú Chulainn said—and he cast his final spear through the last son’s chest.
Lugaid pulled it free and hurled it one last time, striking Cú Chulainn through the stomach, spilling his intestines onto the ground.
A WARRIOR’S LAST STAND
Mortally wounded, Cú Chulainn crawled to a nearby lake for a final drink of water.
His enemies held back, fearing he had more strength left than he showed.
Revived by the water, Cú Chulainn refused to die on the ground like an animal.
He crawled to a standing stone and tied himself to it, gripping his sword tightly.
For three days, he stood there, his eyes unblinking.
None dared approach, fearing he might rise again.
At last, a raven landed on his shoulder.
Seeing this, Lugaid knew it was safe to strike.
He approached to take Cú Chulainn’s sword, but the hero had died with such a grip on his blade that Lugaid could not pry it from his fingers.
Frustrated, he cut the tendons of Cú Chulainn’s hand—but as the sword fell, it sliced off Lugaid’s own hand.
And so, Cú Chulainn, King among Warriors, fell at last.
