§ Of the Fifth Battle: Nirnaeth Arnoediad The Silmarillion

But Maedhros had the help of the Naugrim, both in armed force and in great store of weapons; and the smithies of Nogrod and Belegost were busy in those days. And he gathered together again all his brothers and all the people who would follow them; and the Men of Bór and Ulfang were marshalled and trained for war, and they summoned yet more of their kinsfolk out of the East. Moreover in the west Fingon, ever the friend of Maedhros, took counsel with Himring, and in Hithlum the Noldor and the Men of the house of Hador prepared for war. In the forest of Brethil Halmir, lord of the People of Haleth, gathered his men, and they whetted their axes; but Halmir died ere the war came, and Haldir his son ruled that people. And to Gondolin also the tidings came, to Turgon, the hidden king.
