Thenceforth Ket carried it ever about with him in his girdle, hoping that he might yet use it to destroy some great warrior among the Ulstermen.
One day thereafter Ket made a foray on the men of Ross, and carried away a spoil of cattle.

The host of Ulster and King Conor with them overtook him as he went homeward.

The men of Connacht had also mustered to the help of Ket, and both sides made them ready for battle.
Now a river, namely Brosna, ran between them, and on a hill at one side of this were assembled a number of the noble women of Connacht, who desired greatly to look on the far-famed Ultonian warriors, and above all on Conor the King, whose presence was said to be royal and stately beyond any man that was then living in Erinn.

Among the bushes, close to the women, Ket hid himself, and lay still but watchful.
Now Conor, seeing none but womenfolk close to him at this point, and being willing to show them his splendour, drew near to the bank on his side of the stream.

Then Ket leaped up, whirling his sling, and the bullet hummed across the river and smote King Conor on the temple.
