carried Grainne in his magic mantle to the Brug na Boinne, while Diarmaid alighted like a bird on the shafts of his spears far outside the ring of the Féinn and fought all who opposed him, Oscar, who had pleaded for his forgiveness, accompanying him to Oengus's síd. Meanwhile Fionn sought the help of his nurse from the Land of Promise, and she enveloped the Feinn in a mist, herself flying on the leaf of a water-lily, through a hole in which she dropped darts on Diarmaid. He flung his invincible spear, the gaí dearg, through the hole and killed the witch, whereupon Oengus made peace between Fionn and Diarmaid, who was allowed to keep Grainne.

He begged water, for whoever drank from Fionn's hands would recover from any injury; and he recalled all he had ever done for him, while
