The seneschal of Clamadeu of the Isles spent the better part of a year besieging Beaurepaire in order to win it and its lady Blancheflor for his lord. He had almost reduced it to abject surrender when Percivale arrived and defeated him in single combat.

Conscientiously remembering Gornemant's instructions to grant mercy whenever defeated opponents begged for it, Percivale would have sent Engygeron prisoner to Blancheflor; Engygeron pointed out that she would certainly have him killed, not only for besieging her and her people, but for having had a hand in her father's death. [I find no further details about that incident.] All right, said Percivale, then present yourself prisoner at this castle, describing Gornemant's.

Engygeron recognized it from the description and explained that they hated him there, too, for having killed one of Gornemant's brothers in the Beaurepaire fighting. Thereupon Percivale ordered him to turn himself in at Arthur's court in Dinasdaron, which final charge Engygeron accepted.

The day after his arrival at Arthur's court, he found his lord Clamadeu following him, having suffered almost exactly the same fate at Percivale's hands. Since Clamadeu settled down as a member of Arthur's court for the rest of his life, it might not be preposterous of us to guess that Engygeron did the same.

"Engygeron" is D.D.R. Owen's transcription of the name. "Anguingueron" is Ruth Harwood Cline's.
