The third night was Cuchulain's watch, and he took his post outside the dun, and the gates and wall were secured by magic spells, so that none could enter. Vainly he watched till midnight, and then he thought he saw nine grey shadowy forms creeping towards him. "Who goes there?" he cried. "If you be friends, stop; if foes, come on!" Then the nine shadowy foes raised a shout, and fell upon the hero; but he fought hard and slew them, and beheaded them. A second and a third time similar groups of vague, shadowy foemen rushed at him, and he slew them all in like manner, and then, wearied out, sat down to rest. The Dragon Later on in the night, as he was still watching, he heard a heavy sound, like waves surging in the lake, and when he roused himself to see what it was he beheld a monstrous dragon. It was rising from the water and flying towards the dun, and seemed ready to devour everything in its way. When the dragon perceived him it soared swiftly into the air, and then gradually sank towards him, opening its terrible jaws. Cuchulain sprang up, giving his wonderful hero-leap, and thrust his arm into the dragon's mouth and down its throat; he found its heart, tore it out, and saw the monster fall dead on the ground. He then cut off its scaly head, which he added to those of his former enemies.

The shadow, as before, became a giant, who greeted him in a surly tone with, "This is a bad night." "It will be worse yet for you," said Cuchulain. The giant, as he had done with the other heroes, threw oaks, but just missed him; and when he tried to grapple with him the hero leaped up with drawn sword. In his anger the hero-light shone round him, and he sprang as high as the giant's head, and gave him a stroke that brought him to his knees. "Life for life, Cuchulain," said the giant, and vanished at once, leaving no trace. Cuchulain Re-enters the Dun Now Cuchulain would gladly have returned to the fort to rest, but there seemed no way of entrance, and the hero was vexed at his own helplessness, for he thought his comrades had jumped over the magic walls. Twice he boldly essayed to leap the lofty wall, and twice he failed; then in his wrath his great strength came upon him, the hero-light shone round him, and he took a little run and, leaning on his spear, leaped so high and so far that he alighted in the middle of the court, just before the door of the hall. As he sighed heavily and wearily, Curoi's wife said: "That is the sigh of a weary conqueror, not of a beaten man"; and Cuchulain went in and sat down to rest. The Decision
