The Silmarillion
Then the Elf-friends said: 'You will now believe this at least: there is indeed a Dark Lord, and his spies and emissaries are among us; for he fears us, and the strength that we may give to his foes.'
But some still answered: 'He hates us, rather, and ever the more the longer we dwell here, meddling in his quarrel with the Kings of the Eldar, to no gain of ours.' Many therefore of those that yet remained in Estolad made ready to depart; and Bereg led a thousand of the people of Beor away southwards, and they passed out of the songs of those days. But Amlach repented, saying: 'I have now a quarrel of my own with this Master of Lies, which will last to my life's end'; and he went away north and entered the service of Maedhros. But those of his people who were of like mind with Bereg chose a new leader, and they went back over the mountains into Eriador, and are forgotten.
During this time the Haladin remained in Thargelion and were content. But Morgoth, seeing that by lies and deceits he could not yet wholly estrange Elves and Men, was filled with wrath, and endeavoured to do Men what hurt he could. Therefore he sent out an Orc-raid, and passing east it escaped the leaguer, and came in stealth back over Ered Lindon by the passes of the Dwarf-road, and fell upon the Haladin in the southern woods of the land of Caranthir.
Now the Haladin did not live under the rule of lords or many together, but each homestead was set apart and governed its own affairs, and they were slow to unite. But there was among them a man named Haldad, who was masterful and fearless; and he gathered all the brave men that he could find, and retreated to the angle of land between Ascar and Gelion, and in the utmost comer he built a stockade across from water to water; and behind it they led all the women and children that they could save. There they were besieged, until their food was gone.
Haldad had twin children: Haleth his daughter, and Haldar his son; and both were valiant in the defence, for Haleth was a woman of great heart and strength. But at last Haldad was slain in a sortie against the Orcs; and Haldar, who rushed out to save his father's body from their butchery, was hewn down beside him. Then Haleth held the people together, though they were without hope; and some cast themselves in the rivers and were drowned. But seven days later, as the Orcs made their last assault and had already broken through the stockade, there came suddenly a music of trumpets, and Caranthir with his host came down from the north and drove the Orcs into the rivers.
Then Caranthir looked kindly upon Men and did Haleth great honour; and he offered her recompense for her father and brother. And seeing, over late, what valour there was in the Edain, he said to her: 'If you will remove and dwell further north, there you shall have the friendship and protection of the Eldar, and free lands of your own.'
But Haleth was proud, and unwilling to be guided or ruled, and most of the Haladin were of like mood. t Therefore she thanked Caranthir, but answered: 'My mind is now set, lord, to leave the shadow of the mountains, and go west, whither others of our kin have gone.' When therefore the Haladin had gathered all whom they could find alive of their folk who had fled wild into the woods before the Orcs, and had gleaned what remained of their goods in their burned homesteads, they took Haleth for their chief; and she led them at last to Estolad, and there dwelt for a time. But they remained a people apart, and were ever after known to Elves and Men as the People of Haleth. Haleth remained their chief while her days lasted, but she did not wed, and the headship afterwards passed to Haldan son of Haldar her brother. Soon however Haleth desired to move westward again; and though most of her people were against this counsel, she led them forth once more; and they went without help or guidance of the Eldar, and passing over Celon and Aros they journeyed in the perilous land between the Mountains of Terror and the Girdle of Melian. That land was even then not yet so evil as it after became, but it was no road for mortal Men to take without aid, and Haleth only brought her people through it with hardship and loss, constraining them to go forward by the strength of her will. At last they crossed over the Brithiach, and many bitterly repented of their journey; but there was now no returning.
Therefore in new lands they went back to their old life as best they could; and they dwelt in free homesteads in the woods of Talath Dirnen beyond Teiglin, and some wandered far into the realm of Nargothrond. But there were many who loved the Lady Haleth and wished to go whither she would, and dwell under her rule; and these she led into the Forest of Brethil, between Teiglin and Sirion. Thither in the evil days that followed many of her scattered folk returned.
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, Tur Haretha, the Ladybarrow, Haudh-en-Arwen in the Sindarin tongue.
In this way it came to pass that the Edain dwelt in the lands of the Eldar, some here, some there, some wandering, some settled in kindreds or small peoples; and the most part of them soon learned the Grey-elven tongue, both as a common speech among themselves and because many were eager to learn the lore of the Elves. But after a time the Elf-kings, seeing that it was not good for Elves and Men to dwell mingled together without order, and that Men needed lords of their own kind, set regions apart where Men could live their own lives, and appointed chieftains to hold these lands freely. They were the allies of the Eldar in war, but marched under their own leaders. Yet many of the Edain had delight in the friendship of the Elves, and dwelt among them for so long as they had leave; and the young men often took service for a time in the hosts of the kings.
Now Hador Lorindol, son of Hathol, son of Magor, son of Malach Aradan, entered the household of Fingolfin in his youth, and was loved by the King. Fingolfin therefore gave to him the lordship of Dor-lomin, and into that land he gathered most of the people of his kin, and became the mightiest of the chieftains of the Edain. In his house only the Elven-tongue was spoken; but their own speech was not forgotten, and from it came the common tongue of Numenor.
