Story Summary
Experience the tragic duel of Cú Chulainn at the Ford. Witness the legendary hero of the Ulster Cycle face his dearest friend in a battle of honor and duty.
During the cattle raid of Cooley, Queen Medb of Connacht marched her armies against Ulster. While the men of Ulster lay paralyzed by a divine curse, only the young hero Cú Chulainn remained to defend the border. To stall the invasion, he invoked the right of single combat at the ford. After defeating many champions, Medb manipulated Cú Chulainn’s own foster-brother, Ferdiad, into fighting him. For three days, the two companions fought with honor, stopping each evening to share food and medicine, their hearts heavy with grief. On the fourth day, the battle reached a fever pitch. Ferdiad’s skin was like horn, impenetrable to normal blades. Driven to a divine battle-frenzy, Cú Chulainn called for his secret weapon, the Gáe Bulg. He cast the barbed spear through the water, striking Ferdiad and ending the life of his dearest friend. Cú Chulainn wept over Ferdiad’s body, lamenting the cruel fate that forced brothers to destroy one another for the pride of kings.
The Moral
The highest sense of duty can often lead to the deepest personal tragedy and the loss of what we cherish most.
“Each was a spear to the other, each was a shield to the other.”
Fun Fact
In the myths, Ferdiad had a 'horn skin' that no normal weapon could pierce, which is why Cú Chulainn was forced to use the supernatural Gáe Bulg to win.
