In the front of that fire came Glaurung the golden, father of dragons, in his full might; and in his train were Balrogs, and behind them came the black armies of the Orcs in multitudes such as the Noldor had never before seen or imagined. And they assaulted the fortresses of the Noldor, and broke the leaguer about Angband, and slew wherever they found them the Noldor and their allies. Grey-elves and Men. Many of the stoutest of the foes of Morgoth were destroyed in the first days of that war, bewildered and dispersed and unable to muster their strength. War ceased not wholly ever again in Beleriand; but the Battle of Sudden Flame is held to have ended with the coming of spring, when the onslaught of Morgoth grew less.

Thus ended the Siege of Angband; and the foes of Morgoth were scattered and sundered one from another. The most part of the Grey-elves fled south and forsook the northern war; many were received into Doriath, and the kingdom and strength of Thingol grew greater in that time, for the power of Melian the queen was woven about his borders and evil could not yet enter that hidden realm. Others took refuge in the fortresses by the sea, and in Nargothrond; and some fled the land and hid themselves in Ossiriand, or passing the mountains wandered homeless in the wild. And rumour of the war and the breaking of the siege reached the ears of Men in the east of Middle-earth.

The sons of Finarfin bore most heavily the brunt of the assault, and Angrod and Aegnor were slain; beside them fell Bregolas lord of the house of Bëor, and a great part of the warriors of that people. But Barahir the brother of Bregolas was in the fighting farther westward, near to the Pass of Sirion. There King Finrod Felagund, hastening from the south, was cut off from his people and surrounded with small company in the Pen of Serech; and he would have been slain or taken, but Barahir came up with the bravest of his men and rescued him, and made a wall of spears about him; and they cut their way out of the battle with great loss. Thus Felagund escaped, and returned to his deep fortress of Nargothrond; but he swore an oath of abiding friendship and aid in every need to Barahir and all his kin, and in token of his vow he gave to Barahir his ring. Barahir was now by right lord of the house of Bëor, and he returned to Dorthonion; but most of his people fled from their homes and took refuge in the fastness of Hithlum.

So great was the onslaught of Morgoth that Fingolfin and Fingon could not come to the aid of the sons of Finarfin; and the hosts of Hithlum were driven back with great loss to the fortresses of Ered Wethrin, and these they hardly defended against the Orcs. Before the walls of Eithel Sirion fell Hador the Golden-haired, defending the rearguard of his lord Fingolfin, being then sixty and six years of age, and with him fell Gundor his younger son, pierced with many arrows; and they were mourned by the Elves. Then Galdor the Tall took the lordship of his father. And because of the strength and height of the Shadowy Mountains, which withstood the torrent of fire, and by the valour of the Elves and the Men of the North, which neither Orc nor Balrog could yet overcome, Hithlum remained unconquered, a threat upon the flank of Morgoth's attack; but Fingolfin was sundered from his kinsmen by a sea of foes.

For the war had gone ill with the sons of Fëanor, and well nigh all the east marches were taken by assault The Pass of Aglon was forced, though with great cost to the hosts of Morgoth; and Celegorm and Curufin being defeated fled south and west by the marches of Doriath, and coming at last to Nargothrond sought harbour with Finrod Felagund. Thus it came to pass that their people swelled the strength of Nargothrond; but it would have been better, as was after seen, if they had remained in the east among their own kin. Maedhros did deeds of surpassing valour, and the Orcs fled before his face; for since his torment upon Thangorodrim his spirit burned like a white fire within, and he was as one that returns from the dead. Thus the great fortress upon the Hill of Himring could not be taken, and many of the most valiant that remained, both of the people of Dorthonion and of the east marches, rallied there to Maedhros; and for a while he closed once more the Pass of Aglon, so that the Orcs could not enter Beleriand by that road. But they overwhelmed the riders of the people of Fëanor upon Lothlann, for Glaurung came thither, and passed through Maglor's Gap, and destroyed all the land between the arms of Gelion. And the Orcs took the fortress upon the west slopes of Mount Rerir, and ravaged all Thargelion, the land of Caranthir; and they defiled Lake Helevorn. Thence they passed over Gelion with fire and terror and came far into East Beleriand. Maglor joined Maedhros upon Himring; but Caranthir fled and joined the remnant of his people to the scattered folk of the hunters, Amrod and Amras, and they retreated and passed Ramdal in the south. Upon Amon Ereb they maintained a watch and some strength of war, and they had aid of the Green-elves; and the Orcs came not into Ossiriand, nor to Taur-im-Duinath and the wilds of the south.

Now news came to Hithlum that Dorthonion was lost and the sons of Finarfin overthrown, and that the sons of Fëanor were driven from their lands. Then Fingolfin beheld (as it seemed to him) the utter ruin of the Noldor, and the defeat beyond redress of all their houses; and filled with wrath and despair he mounted upon Rochallor his great horse and rode forth alone, and none might restrain him. He passed over Dor-nu-Fauglith like a wind amid the dust, and all that beheld his onset fled in amaze, thinking that Oromë himself was come: for a great madness of rage was upon him, so that his eyes shone like the eyes of the Valar. Thus he came alone to Angband's gates, and he sounded his horn, and smote once more upon the brazen doors, and challenged Morgoth to come forth to single combat. And Morgoth came.

That was the last time in those wars that he passed the doors of his stronghold, and it is said that he took not the challenge willingly; for though his might was greatest of all things in this world, alone of the Valar he knew fear. But he could not now deny the challenge before the face of his captains; for the rocks rang with the shrill music of Fingolfin's horn, and his voice came keen and clear down into the depths of Angband; and Fingolfin named Morgoth craven, and lord of slaves. Therefore Morgoth came, climbing slowly from his subterranean throne, and the rumour of his feet was like thunder underground. And he issued forth clad in black armour; and he stood before the King like a tower, iron-crowned, and his vast shield, sable on-blazoned, cast a shadow over him like a stormcloud. But Fingolfin gleamed beneath it as a star; for his mail was overlaid with silver, and his blue shield was set with crystals; and he drew his sword Ringil, that glittered like ice.

Then Morgoth hurled aloft Grond, the Hammer of the Underworld, and swung it down like a bolt of thunder. But Fingolfin sprang aside, and Grond rent a mighty pit in the earth, whence smoke and fire darted. Many times Morgoth essayed to smite him, and each time Fingolfin leaped away, as a 'lightning shoots from under a dark cloud; and he wounded Morgoth with seven wounds, and seven times Morgoth gave a cry of anguish, whereat the hosts of Angband fell upon their faces in dismay, and the cries echoed in the Northlands.

But at the last the King grew weary, and Morgoth bore down his shield upon him. Thrice he was crushed to his knees, and thrice arose again and bore up his broken shield and stricken helm. But the earth was all rent and pitted about him, and he stumbled and fell backward before the feet of Morgoth; and Morgoth set his left foot upon his neck, and the weight of it was like a fallen hill. Yet with his last and desperate stroke Fingolfin hewed the foot with Ringil, and the blood gashed forth black and smoking and filled the pits of Grond.
