That night the men slept in the house of Custennin the herdsman, and the next day they proceeded to the castle, and entered the hall, and said:
'Yspaddaden Penkawr, give us thy daughter and thou shalt keep her dower. And unless thou wilt do this we will slay thee.'
'Her four great grandmothers and her four great grandfathers yet live,' answered Yspaddaden Penkawr; 'it is needful that I take counsel with them.'
'Be it so; we will go to meat,' but as they turned he took up the second dart that lay by his side and cast it after them. And Menw caught it, and flung it at him, and wounded him in the chest, so that it came out at his back.
'A gentle son-in-law, truly!' cried Yspaddaden; 'the iron pains me like the bite of a horse-leech. Cursed be the hearth whereon it was heated, and the smith who formed it!'
The third day Arthur's men returned to the palace into the presence of Yspaddaden.
'Shoot not at me again,' said he, 'unless you desire death. But lift up my eyebrows, which have fallen over my eyes, that I may see my son-in-law.' Then they arose, and as they did so Yspaddaden Penkawr took the third poisoned dart and cast it at them. And Kilwch caught it, and flung it back, and it passed through his eyeball, and came out on the other side of his head.
'A gentle son-in-law, truly! Cursed be the fire in which it was forged and the man who fashioned it!'
The next day Arthur's men came again to the palace and said:
'Shoot not at us any more unless thou desirest more pain than even now thou hast, but give us thy daughter without more words.'
