§ Of the Flight of the Noldor 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.
