Of the march of the host of the Valar to the north of Middle-earth little is said in any tale; for among them went none of those Elves who had dwelt and suffered in the Hither Lands, and who made the histories of those days that still are known; and tidings of these things they only learned long afterwards from their kinsfolk in Aman. But at the last the might of Valinor came up out of the West, and the challenge of the trumpets of Eönwë filled the sky; and Beleriand was ablaze with the glory of their arms, for the host of the Valar were arrayed in forms young and fair and terrible, and the mountains rang beneath their feet.
The meeting of the hosts of the West and of the North is named the Great Battle, and the War of Wrath. There was marshalled the whole power of the Throne of Morgoth, and it had become great beyond count, so that Anfauglith could not contain it; and all the North was aflame with war.
But it availed him not. The Balrogs were destroyed, save some few that fled and hid themselves in caverns inaccessible at the roots of the earth; and the uncounted legions of the Ores perished like straw in a great fire, or were swept like shrivelled leaves before a burning wind. Few remained to trouble the world for long years after. And such few as were left of the three houses of the Elf-friends, Fathers of Men, fought upon the part of the Valar; and they were avenged in those days for Baragund and Barahir, Galdor and Gundor, Huor and Húrin, and many others of their lords. But a great part of the sons of Men, whether of the people of Uldor or others new-come out of the east, marched with the Enemy; and the Elves do not forget it.
Then, seeing that his hosts were overthrown and his power dispersed, Morgoth quailed, and he dared not to come forth himself. But he loosed upon his foes the last desperate assault that he had prepared, and out of the pits of Angband there issued the winged dragons, that had not before been seen; and so sudden and ruinous was the onset of that dreadful fleet that the host of the Valar was driven back, for the coming of the dragons was with great thunder, and lightning, and a tempest of fire.
But Eärendil came, shining with white flame, and about Vingilot were gathered all the great birds of heaven and Thorondor was their captain, and there was battle in the air all the day and through a dark night of doubt. Before the rising of the sun Eärendil slew Ancalagon the Black, the mightiest of the dragon-host, and cast him from the sky; and he fell upon the towers of Thangorodrim, and they were broken in his ruin. Then the sun rose, and the host of the Valar prevailed, and well-nigh all the dragons were destroyed; and all the pits of Morgoth were broken and unroofed, and the might of the Valar descended into the deeps of the earth. There Morgoth stood at last at bay, and yet unvaliant. He fled into the deepest of his mines, and sued for peace and pardon; but his feet were hewn from under him, and he was hurled upon his face. Then he was bound with the chain Angainor which he had worn aforetime, and his iron crown they beat into a collar for his neck, and his head was bowed upon his knees. And the two Silmarils which remained to Morgoth were taken from his crown, and they shone unsullied beneath the sky; and Eönwë took them, and guarded them.
Thus an end was made of the power of Angband in the North, and' the evil realm was brought to naught; and out of the deep prisons a multitude of slaves came forth beyond all hope into the light of day, and they looked upon a world that was changed. For so great was the fury of those adversaries that the northern regions of the western world were rent asunder, and the sea roared in through many chasms, and there was confusion and great noise; and rivers perished or found new paths, and the valleys were upheaved and the hills trod down; and Sirion was no more.
Then Eönwë as herald of the Elder King summoned the Elves of Beleriand to depart from Middle-earth. But Maedhros and Maglor would not hearken, and they prepared, though now with weariness and loathing, to attempt in despair the fulfilment of their oath; for they would have given battle for the Silmarils, were they withheld, even against the victorious host of Valinor, even though they stood alone against all the world. And they sent a message therefore to Eönwë, bidding him yield up now those jewels which of old Fëanor their father made and Morgoth stole from him.
But Eönwë answered that the right to the work of their father, which the sons of Fëanor formerly possessed, had now perished, because of their many and merciless deeds, being blinded by their oath, and most of all because of their slaying of Dior and the assault upon the Havens. The light of the Silmarils should go now into the West, whence it came in the beginning; and to Valinor must Maedhros and Maglor return, and there abide the judgement of the Valar, by whose decree alone would Eönwë yield the jewels from his charge. Then Maglor desired indeed to submit, for his heart was sorrowful, and he said: The oath says not that we may not bide our time, and it may be that in Valinor all shall be forgiven and forgot, and we shall come into our own in peace.
But Maedhros answered that if they returned to Aman but the favour of the Valar were withheld from them, then their oath would still remain, but its fulfilment be beyond all hope; and he said: 'Who can tell to what dreadful doom we shall come, if we disobey the Powers in their own land, or purpose ever to bring war again into their holy realm?'
Yet Maglor still held back, saying: 'If Manwë and Varda themselves deny the fulfilment of an oath to which we named them in witness, is it not made void?'
And Maedhros answered: 'But how shall our voices reach to Ilúvatar beyond the Circles of the World? And by Ilúvatar we swore in our madness, and called the Everlasting Darkness upon us, if we kept not our word. Who shall release us?'
'If none can release us,' said Maglor, 'then indeed the Everlasting Darkness shall be our lot, whether we keep our oath or break it; but less evil shall we do in the breaking.'
Yet he yielded at last to the will of Maedhros, and they took counsel together how they should lay hands on the Silmarils. And they disguised themselves, and came in the night to the camp of Eönwë, and crept into the place where the Silmarils were guarded; and they slew the guards, and laid hands on the jewels. Then all the camp was raised against them, and they prepared to die, defending themselves until the last. But Eönwë would not permit the slaying of the sons of Fëanor; and departing unfought they fled far away. Each of them took to himself a Silmaril, for they said: 'Since one is lost to us, and but two remain, and we two alone of our brothers, so is it plain that fate would have us share the heirlooms of our father.'
But the jewel burned the hand of Maedhros in pain unbearable; and he perceived that it was as Eönwë had said, and that his right thereto had become void, and that the oath was vain. And being in anguish and despair he cast himself into a gaping chasm filled with fire, and so ended; and the Silmaril that he bore was taken into the bosom of the Earth,
And it is told of Maglor that he could not endure the pain with which the Silmaril tormented him; and he cast it at last into the Sea, and thereafter he wandered ever upon the shores, singing in pain and regret beside the waves. For Maglor was mighty among the singers of old, named only after Daeron of Doriath; but he came never back among the people of the Elves. And thus it came to pass that the Silmarils found their long homes: one in the airs of heaven, and one in the fires of the heart of the world, and one in the deep waters.
In those days there was a great building of ships upon the shores of the Western Sea; and thence in many a fleet the Eldar set sail into the West, and came never back to the lands of weeping and of war. And the Vanyar returned beneath their white banners, and were borne in triumph to Valinor; but their joy in victory was diminished, for they returned without the Silmarils from Morgoth's crown, and they knew that those jewels could not be found or brought together again unless the world be broken and remade.
