They met in combat and fought till the night was coming. Then Thin-in-Iron cried out for a cessation, and if he did, Cucúlin was glad to give it; for his sword had no effect upon Thin-in-Iron except to tire and nearly kill him (he was enchanted and no arms could cut him). When Thin-in-Iron went to his castle, he threw up three sups of blood, and said to his housekeeper: "Though his sword could not penetrate me, he has nearly broken my heart."
Cucúlin had to be carried to his tent. His comrades laid him on his bed and said: "Whoever came and healed him yesterday, may be the same will be here to-night." They went away and were not long gone when Gil an Og came and said: "Cucúlin, if you had done my bidding, you would n't be as you are to-night. But if you neglect my words now, you 'll never see my face again. I 'll cure you this time and make you as well as ever; "and whatever virtue she had she healed him so he was as strong as before.
"Oh, then," said Cucúlin, "whatever comes on me I 'll never turn back till I knock another day's trial out of Thin-in-Iron."
"Well," said she, "you are a stronger man than he, but there is no good in working at him with a sword. Throw your sword aside to-morrow, and you 'll get the better of him and bind him. You 'll not see me again."
