§ Of Túrin Turambar The Silmarillion

Soon afterwards Handir Lord of Brethil was slain, for the Orcs invaded his land, and Handir gave them battle; but the Men of Brethil were worsted, and driven back into their woods. And in the autumn of the year, biding his hour, Morgoth loosed upon the people of Narog the great host that he had long prepared; and Glaurung the Úrulóki passed over Anfauglith, and came thence into the north vales of Sirion and there did great evil. Under the shadows of Ered Wethrin he defiled the Eithel Ivrin, and thence he passed into the realm of Nargothrond, and burned the Talath Dirnen, the Guarded Plain, between Narog and Teiglin.
