§ Of the Coming of Men into the West The Silmarillion

Now Brethil was claimed as part of his realm by King Thingol, though it was not within the Girdle of Melian, and he would have denied it to Haleth; but Felagund, who had the friendship of Thingol, hearing of all that had befallen the People of Haleth, obtained this grace for her: that she should dwell free in Brethil, upon the condition only that her people should guard the Crossings of Teiglin against all enemies of the Eldar, and allow no Orcs to enter their woods. To this Haleth answered: 'Where are Haldad my father, and Haldar my brother? If the King of Doriath fears a friendship between Haleth and those who have devoured her kin, then the thoughts of the Eldar are strange to Men.' And Haleth dwelt in Brethil until she died; and her people raised a green mound over her in the heights of the forest, Tûr Haretha, the Ladybarrow, Haudh-en-Arwen in the Sindarin tongue.
