Meanwhile Finn had discovered their flight, and his rage knew no bounds. He sent his trackers, the Clann Neamhuain[252], to follow them. They tracked them to the wood, and one of them climbed a tree, and, looking down, saw the hut, with a strong seven-doored fence built round it, and Diarmait and Grainne inside. When the news came to the Fenians, they were sorry, for their sympathies were with Diarmait and not with Finn. They tried to warn him, but he took no heed; for he had determined to fight and not to flee. Indeed, when Finn himself came to the fence, and called over it to Diarmait, asking if he and Grainne were within, he replied that they were, but that none should enter unless he gave permission. So Diarmait, like Cuchulainn in the war of Ulster against Ireland, found himself matched single-handed against a host. But, also like Cuchulainn, he had a divine helper. The favourite of the Tuatha Dé Danann, he had been the pupil of Manannán son of Lêr in the “Land of Promise”, and had been fostered by Angus of the Brugh. Manannán had given him his two spears, the “Red Javelin” and the “Yellow Javelin”, and his two swords, the “Great Fury” and the “Little Fury”. And now Angus came to look for his foster-son, and brought with him the magic mantle of invisibility used by the gods. He advised Diarmait and Grainne to come out wrapped in the cloak, and thus rendered invisible. Diarmait still refused to flee, but asked Angus to protect Grainne. Wrapping the magic mantle round her, the god led the princess away unseen by any of the Fenians. By this time, Finn had posted men outside all the seven doors in the fence. Diarmait went to each of them in turn. At the first, were Ossian and Oscar with the Clann Baoisgne. They offered him their protection. At the second, were Caoilte and the Clann Ronan, who said they would fight to the death for him. At the third, were Conan and the Clann Morna, also his friends. At the fourth, stood Cuan with the Fenians of Munster, Diarmait’s native province. At the fifth, were the Ulster Fenians, who also promised him protection against Finn. But at the sixth, were the Clann Neamhuain, who hated him; and at the seventh, was Finn himself. “It is by your door that I will pass out, O Finn,” cried Diarmait. Finn charged his men to surround Diarmait as he came out, and kill him. But he leaped the fence, passing clean over their heads, and fled away so swiftly that they could not follow him. He never halted till he reached the place to which he knew Angus had taken Grainne. The friendly god left them with a little sage advice: never to hide in a tree with only one trunk; never to rest in a cave with only one entrance; never to land on an island with only one channel of approach; not to eat their supper where they had cooked it, nor to sleep where they had supped, and, where they had slept once, never to sleep again. With these Red-Indian-like tactics, it was some time before Finn discovered them.
