Then Kylta Mac Ronan went to the top of a high hill; and, turning his face inland, he uttered three mighty shouts, which were taken up by the people of the next valley, and after them by those of the next valley beyond. And so the signal spread, till a shout of alarm was heard in every plain and hill-side, glen and valley, wood and wilderness, in the two provinces of Munster. And when the Fena heard these shouts, they ceased anon from their sports and pastimes; for they knew their king was in danger or strait of some kind. And they formed themselves into ranks and troops and battalions, and began their march; and it is not told how they fared till they reached Cloghan Kincat. Finn told them the whole story of the Gilla Dacker and his horse, and how he had carried away Conan and fifteen others to some far-off island in the Western Ocean. He also showed them the ship, and told them that he himself and a chosen band of the Fena were about to sail westward in quest of their friends. And Oisin asked him how many of the chief men of the Fena he wished to take with him. Finn replied, "I foresee that this will be a perilous quest; and I think all the chiefs here present few enough to bring with me." "Say not so, O king," said Oisin; "too many have gone already, and some must be left behind to guard the country, and to keep order. If fifteen good men go with you, and that you find the others, the whole party will be a match for any foe you are like to meet in these western lands." And Oscar and Gaul Mac Morna spoke in like manner. To this Finn agreed. Then he picked out fifteen men, the bravest and best, the most dexterous at the sword, and the swiftest of foot among the Fena. The question then arose, who should lead the Fena in the king's absence; and what they agreed on was that Oisin should remain behind and take command, as he was the eldest and bravest and wisest of the king's sons. Of those who were chosen to go with Finn, the chief men were Dermat O'Dyna; Gaul Mac Morna; Oscar, the son of Oisin; Aed Beg, the son of Finn; Fergus Finnvel, the poet; the three sons of Encarda; and Feradach and Foltlebar, the two sons of the king of Innia. So the king and his party took leave of Oisin and the rest. And sad, indeed, were they on both sides; for no one knew how far the king might have to sail among unknown seas and islands, or how long he should be away from Erin, or the spells and dangers he and his men might encounter in this pursuit.
