Beloe

Belec, Belee, Beloc, Beloee, Beloie

When Arthur returned from France on news of Mordred's rebellion, the party bearing Gawaine's body stopped at Beloe Castle for the night.

The lady of Beloe grieved for Gawaine as the only man she had ever loved. Upon this, the lord of Beloe, who had never liked Gawaine, struck her with his sword upon hearing this, and she died after requesting burial alongside Gawaine. For this murder, the lord was killed in turn by Arthur's knights, who then carried the lady's body with Gawaine's to Camelot as she requested.

Mordred had attacked Arthur at Dover, trying to prevent his landing. Beloe must be between Dover and, probably, London or Camelot.
