For unsummoned and unlocked for Turgon had opened the leaguer of Gondolin, and was come with an army ten thousand strong, with bright mail and long swords and spears like a forest. Then when Fingon heard afar the great trumpet of Turgon his brother, the shadow passed and his heart was uplifted, and he shouted aloud: 'Ut?lie'n aur?! Aiya Eldali? ar Atanat?ri, ut?lie'n aur?! The day has come! Behold, people of the Eldar and Fathers of Men, the day has come!' And all those who heard his great voice echo in the hills answered crying: 'Auta i l?m?! The night is passing!'
Now Morgoth, who knew much of what was done and designed by his enemies, chose his hour, and trusting in his treacherous servants to hold back Maedhros and prevent the union of his foes he sent a force seeming great (and yet but part of all that he had made ready) towards Hithlum; and they were clad all in dun raiment and showed no naked steel, and thus were already far over the sands of Anfauglith before their approach was seen.
Then the hearts of the Noldor grew hot, and their captains wished to assail their foes upon the plain; but H?rin spoke against it, and bade them beware of the guile of Morgoth, whose strength was always greater than it seemed, and his purpose other than he revealed. And though the signal of the approach of Maedhros came not, and the host grew impatient, H?rin urged them still to await it, and to let the Orcs break themselves in assault upon the hills.
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.
By ill chance, at that place in the outworks stood Gwindor of Nargothrond, the brother of Gelmir. Now his wrath was kindled to madness, and he leapt forth on horseback, and many riders with him; and they pursued the heralds and slew them, and drove on deep into the main host. And seeing this all the host of the Noldor was set on fire, and Fingon put on his white helm and sounded his trumpets, and all the host of Hithlum leapt forth from the hills in sudden onslaught. The light of the drawing of the swords of the Noldor was like a fire in a field of reeds; and so fell and swift was their onset that almost the designs of Morgoth went astray. Before the army that he sent westward could be strengthened it was swept away, and the banners of Fingon passed over Anfauglith and were raised before the walls of Angband. Ever in the forefront of that battle went Gwindor and the Elves of Nargothrond, and even now they could not be restrained; and they burst through the Gate and slew the guards upon the very stairs of Angband, and Morgoth trembled upon his deep throne, hearing them beat upon his doors. But they were trapped there, and all were slain save Gwindor only, whom they took alive; for Fingon could not come to their aid. By many secret doors in Thangorodrim Morgoth had let issue forth his main host that he held in waiting, and Fingon was beaten back with great loss from the walls.
Then in the plain of Anfauglith, on the fourth day of the war, there began Nirnaeth Arnoediad, Unnumbered Tears, for no song
