§ Of the Ruin of Beleriand and the Fall of Fingolfin The Silmarillion

Thus ended the Siege of Angband; and the foes of Morgoth were scattered and sundered one from another. The most part of the Grey-elves fled south and forsook the northern war; many were received into Doriath, and the kingdom and strength of Thingol grew greater in that time, for the power of Melian the queen was woven about his borders and evil could not yet enter that hidden realm. Others took refuge in the fortresses by the sea, and in Nargothrond; and some fled the land and hid themselves in Ossiriand, or passing the mountains wandered homeless in the wild. And rumour of the war and the breaking of the siege reached the ears of Men in the east of Middle-earth.
