§ Of the Fifth Battle: Nirnaeth Arnoediad The Silmarillion

But the Captain of Morgoth in the west had been commanded to draw out Fingon swiftly from his hills by whatever means he could. He marched on therefore until the front of his battle was drawn up before the stream of Sirion, from the walls of the fortress of Eithel Sirion to the inflowing of Rivil at the Fen of Serech; and the outposts of Fingon could see the eyes of their enemies. But there was no answer to his challenge, and the taunts of the Orcs faltered as they looked upon the silent walls and the hidden threat of the hills. Then the Captain of Morgoth sent out riders with tokens of parley, and they rode up before the outworks of the Barad Eithel. With them they brought Gelmir son of Guilin, that lord of Nargothrond whom they had captured in the Bragollach; and they had blinded him. Then the heralds of Angband showed him forth, crying: 'We have many more such at home, but you must make haste if you would find them; for we shall deal with them all when we return even so.' And they hewed off Gelmir's hands and feet, and his head last, within sight of the Elves, and left him.
