Fin MacCumhail and the Son of the King of Alba

The Gruagach carries a club of a ton weight, and if the cowherd gets one welt of that club, he'll never trouble the Fenians of Erin again."

Next morning Fin called up the cowherd and said, "I am going to have a feast in this castle, and I would like to have some fresh pork. There is a wild sow in the north of Erin with two pigs, and if you bring her to me before the feast, you'll have my thanks."

"I'll go and bring her to you," said the cowherd. So after breakfast he took his sword, went to the north of Erin, and stole up to the sow and two pigs, and whipped the tails off the three of them, before they knew he was in it. Then he faced the wild sow and fought with her for four days and five nights, and on the morning of the fifth day he knocked her dead. At the last blow, his sword stuck in her backbone and he couldn't draw it out. But with one pull he broke the blade, and stood there over her with only the hilt in his hand. Then he put his foot on one of her jaws, took the other in his hands, and splitting her evenly from the nose to the tail, made two halves of her.

He threw one half on his shoulder; and that minute the big Gruagach with one eye in his head came along and made an offer of his club at him to kill him. But the cowherd jumped aside, and catching the Gruagach by one of his legs, threw him up on to the half of the wild sow on his shoulder, and taking the other half of her from the ground, clapped that on the top of the Gruagach, and ran away to Fin's castle as fast as his legs could carry him.

The sentry at the castle gate ran in and said: "The cowherd is running to the castle, and the size of a mountain on his back." "Go out now," said Conán Maol, "and stop him where he is, or he'll throw down the castle if he comes here with the load that's on him." But before the sentry was back at his place, the cowherd was at the gate shaking the load off his back and the castle to its foundations, so that every dish and vessel in it was broken to bits.

The Gruagach jumped from the ground, rubbed his legs and every part of him that was sore from the treatment he got.
