Seeing that this was the kind of adventure that Arthur loved, they journeyed back to the King, and told him all. So he prepared a great army, and marched by land to attack Gloucester Castle. But while he fought before the gates, Kai and Bedivere had sailed down the river on the shoulders of the Salmon of Lone Lake, and, finding the water-side portion of the Castle unprotected, they broke through the wall, and carried off Mabon, the son of Modron, and he returned with them to Arthur's Court.

V. How Prince Kilhugh won his Bride

While Arthur and his knights were discussing which of the Impossible Tasks should next be undertaken, it so happened that a certain prince, named Gwyther, who was also one of Arthur's knights, was walking over a mountain in his own country, the Land of the Dawn.

And as he walked, deep in thought, he heard a sad little cry. Up and down he looked, but nothing could he see that could explain such mournful cry. But presently it came again from under his very feet, and there he saw an ant-hill. Inside the ant-hill the little creatures were wailing piteously, for the heath on the mountain-side was afire, and in a short time their kingdom would be all in a blaze.

Then Prince Gwyther drew his sword, and cut off the ant-hill at a blow, and threw it into a place of safety.

"Our grateful thanks are thine," cried the ants. "Now tell us what we can do for thee in return, Prince Gwyther of the Land of the Dawn."

The Prince pondered a moment, and then replied: "All the world knows that Kilhugh, one of the Companions of Arthur, seeking the hand of the fair Olwen, is required by her father to bring him the nine bushels of flax seed sown in his field to make the wedding veil for his bride. If one grain is missing the marriage will be forbidden; and, though we are Arthur's knights, not one of us can find these tiny seeds. Now, can ye do this task for me?"

"That will we joyfully," cried the ants, and they made their way in haste to the field of Thornogre Thistlehair, Chief of the Giants.
