The Silmarillion

Therefore Fëanor halted and the Noldor debated what course they should now take. But they began to suffer anguish from the cold, and the clinging mists through which no gleam of star could pierce; and many repented of the road and began to murmur, especially those that followed Fingolfin, cursing Fëanor, and naming him as the cause of all the woes of the Eldar. But Fëanor, knowing all that was said, took counsel with his sons; and two courses only they saw to escape from Araman and come into Endor: by the straits or by ship. But the Helcaraxë they deemed impassable, whereas the ships were too few. Many had been lost upon their long journey, and there remained now not enough to bear across all the great host together; yet none were willing to abide upon the western coast while others were ferried first: already the fear of treachery was awake among the Noldor. Therefore it came into the hearts of Fëanor and his sons to seize all the ships and depart suddenly; for they had retained the mastery of the fleet since the battle of the Haven, and it was manned only by those who had fought there and were bound to Fëanor. And as though it came at his call, there sprang up a wind from the north-west, and Fëanor slipped away secretly with all whom he deemed true to him, and went aboard, and put out to sea, and left Fingolfin in Araman. And since the sea was there narrow, steering east and somewhat south he passed over without loss, and first of all the Noldor set foot once more upon the shores of Middle-earth; and the landing of Fëanor was at the mouth of the firth which was called Drengist and ran into Dor-lómin.

But when they were landed, Maedhros the eldest of his sons, and on a time the friend of Fingon ere Morgoth's lies came between, spoke to Fëanor, saying: 'Now what ships and rowers will you spare to return, and whom shall they bear hither first? Fingon the valiant?'

Then Fëanor laughed as one fey, and he cried: 'None and none! What I have left behind I count now no loss; needless baggage on the road it has proved. Let those that cursed my name, curse me still, and whine their way back to the cages of the Valar! Let the ships burn!' Then Maedhros alone stood aside, but Fëanor caused fire to be set to the white ships of the Teleri. So in that place which was called Losgar at the outlet of the Firth of Drengist ended the fairest vessels that ever sailed the sea, in a great burning, bright and terrible. And Fingolfin and his people saw the light afar off, red beneath the clouds; and they knew that they were betrayed. This was the firstfruits of the Kinslaying and the Doom of the Noldor.

Then Fingolfin seeing that Fëanor had left him to perish in Araman or return in shame to Valinor was filled with bitterness; but he desired now as never before to come by some way to Middle-earth, and meet Fëanor again. And he and his host wandered long in misery, but their valour and endurance grew with hardship; for they were a mighty people, the elder children undying of Eru Ilúvatar, but new-come from the Blessed Realm, and not yet weary with the weariness of Earth. The fire of their hearts was young, and led by Fingolfin and his sons, and by Finrod and Galadriel, they dared to pass into the bitterest North; and finding no other way they endured at last the terror of the Helcaraxë and the cruel hills of ice. Few of the deeds of the Noldor thereafter surpassed that desperate crossing in hardihood or woe. There Elenwë the wife of Turgon was lost, and many others perished also; and it was with a lessened host that Fingolfin set foot at last upon the Outer Lands. Small love for Fëanor or his sons had those that marched at last behind him, and blew their trumpets in Middle-earth at the first rising of the Moon.

Chapter 10 Of the Sindar

Now as has been told the power of Elwë and Melian increased in Middle-earth, and all the Elves of Beleriand, from the mariners of Círdan to the wandering hunters of the Blue Mountains beyond the River Gelion, owned Elwë as their lord; Elu Thingol he was called, King Greymantle, in the tongue of his people. They are called the Sindar, the Grey-elves of starlit Beleriand; and although they were Moriquendi, under the lordship of Thingol and the teaching of Melian they became the fairest and the most wise and skilful of all the Elves of Middle-earth. And at the end of the first age of the Chaining of Melkor, when all the Earth had peace and the glory of Valinor was at its noon, there came into the world Lúthien, the only child of Thingol and Melian. Though Middle-earth lay for the most part in the Sleep of Yavanna, in Beleriand under the power of Melian there was life and joy, and the bright stars shone as silver fires; and there in the forest of Neldoreth Lúthien was born, and the white flowers of niphredil came forth to greet her as stars from the earth.
