But even as the vanguard of Maedhros came upon the Orcs, Morgoth loosed his last strength, and Angband was emptied. There came wolves, and wolfriders, and there came Balrogs, and dragons, and Glaurung father of dragons. The strength and terror of the Great Worm were now great indeed, and Elves and Men withered before him; and he came between the hosts of Maedhros and Fingon and swept them apart...
Last of all the eastern force to stand firm were the Dwarves of Belegost, and thus they won renown. For the Naugrim withstood fire more hardily than either Elves or Men, and it was their custom more-over to wear great masks in battle hideous to look upon; and those that stood them in good stead against the dragons. And but for them Glaurung and his brood would have withered all that was left of the Noldor. But the Naugrim made a circle about him when he assailed them, and even his mighty armor was not full proof against the blows of their great axes; and when in his rage Glaurung turned and struck down Azaghal, Lord of Belegost, and crawled over him, with his last stroke Azaghal drove a knife into his belly, and so wounded him that he fled the field, and the beasts of Angband in dismay followed after him. Then the Dwarves raised up the body of Azaghal and bore it away; and with slow steps they walked behind singing a dirge in deep voices, as it were a funeral pomp in their country, and gave no heed more to their foes; and none dared stay them
But now in the western battle Fingon and Turgon were assailed by a tide of foes thrice greater than all the force that was left to them. Gothmog, Lord of Balrogs, high-captain of Angband, was come; and he drove a wedge between the Elvenhosts, surrounding King Fingon, and thrusting Turgon and Hurin aside towards the Fen of Serech. Then he turned upon Fingon. That was a grim meeting. At last Fingon stood alone with his guard dead about him; and he fought with Gothmog, until another Balrog came behind and cast a thong of fire about him. Then Gothmog hewed him with his black axe, and a white flame sprang up from the helm of Fingon as it was cloven. Thus fell the High King of the Noldor; and they beat him into the dust with their maces, and his banner, blue and silver, they trod into the mire of his blood.
The field was lost; but still Hurin and Huor and the remnant of house of Hador stood firm with Turgon of Gondolin, and the hosts of Morgoth could not yet win the Pass of Sirion. Then Hurin spoke to Turgon, saying: 'Go now, lord, while time is! For in you lives the last hope of the Eldar, and while Gondolin stands Morgoth shall still know fear in his heart.'
So it was that Turgon fought his way southward, until coming behind the guard of Hurin and Huor he passed down the Sirion and escaped; and he vanished into the mountains and was hidden from the eyes of Morgoth. But the brothers drew the remnant of Men of the house of Hador about them, and foot by foot they withdrew, until they came behind the Fen of Serech, and had the stream of Rivil before them. There they stood and gave way no more.
Then all the hosts of Angband swarmed against them, and they bridged the stream with their dead, and encircled the remnant of Hithlum as a gathering tide about a rock. There as the sun westered on the sixth day, and the shadow of Ered Wethrin grew dark, Huor fell pierced with a venomed arrow in his eye, and all the valiant Men of Hador were slain about him in a heap; and the Orcs hewed their heads and piled them as a mound of gold in the sunset.
Last of all Hurin stood alone. Then he cast aside his shield, and wielded an axe two-handed; and it is sung that the axe smoked in the black blood of the troll-guard of Gothmog until it withered, and each time he slew Hurin cried: 'Aure entuluva! Day shall come again!' Seventy times he uttered that cry; but they took him at last alive, by the command of Morgoth, for the Orcs grappled him with their hands, which clung to him still though he hewed off their arms; and ever their numbers renewed, until at last he fell buried beneath them. Then Gothmog bound him and dragged him to Angband with mockery.
Thus ended Nirnaeth Arnoediad, as the sun went down beyond the sea. Night fell in Hithlum, and there came a great storm of wind out of the West.
