Drutwyn the whelp of Greid, the son of
Eri, and Gwarthegyd the son of Kaw, in another quarter, with the two dogs
of Glythmyr Ledewig, and Bedwyr leading Cavall, Arthur's own dog. And
all the warriors ranged themselves around the Nyver. And there came
there the three sons of Cleddyf Divwlch, men who had gained much fame at
the slaying of Yskithyrwyn Penbaedd; and they went on from Glyn Nyver,
and came to Cwm Kerwyn.

And there Twrch Trwyth made a stand, and slew four of Arthur's champions,
Gwarthegyd the son of Kaw, and Tarawc of Allt Clwyd, and Rheidwn the son
of Eli Atver, and Iscovan Hael. And after he had slain these men, he
made a second stand in the same place. And there he slew Gwydre the son
of Arthur, and Garselit Wyddel, and Glew the son of Ysgawd, and Iscawn
the son of Panon; and there he himself was wounded.

And the next morning before it was day, some of the men came up with him.
And he slew Huandaw, and Gogigwr, and Penpingon, three attendants upon
Glewlwyd Gavaelvawr, so that Heaven knows he had not an attendant
remaining, excepting only Llaesgevyn, a man from whom no one ever derived
any good. And together with these, he slew many of the men of that

stand, and where he slew Kyflas {111b} the son of Kynan, and Gwilenhin
king of France. Then he went as far as Glyn Ystu, and there the men and
the dogs lost him.

Then Arthur summoned unto him Gwyn ab Nudd, and he asked him if he knew
aught of Twrch Trwyth. And he said that he did not.

And all the huntsmen went to hunt the swine as far as Dyffryn Llychwr.
And Grugyn Gwallt Ereint, and Llwydawg Govynnyad closed with them and
killed all the huntsmen, so that there escaped but one man only. And
Arthur and his hosts came to the place where Grugyn and Llwydawg were.
And there he let loose the whole of the dogs upon them, and with the
shout and barking that was set up, Twrch Trwyth came to their assistance.

And from the time that they came across the Irish sea, Arthur had never
got sight of him until then. {111c} So he set men and dogs upon him, and
thereupon he started off and went to Mynydd Amanw. And there one of his
young pigs was killed. {112a} Then they set upon him life for lif
