The Shaping of Middle-earth. Christopher Tolkien
section was changed very soon after it was written, since in §17 already as first written the Nauglafring is with Elwing at the mouth of Sirion:
After vain bargaining the sons of Fëanor made war on him (the second slaying of Elf by Elf) and destroyed him. But Elwing daughter of Dior, Beren’s son, escaped, and was carried away by faithful servants to the mouth of the river Sirion. With her went the Nauglafring.
The great river Sirion flowed through the lands South-west; at its mouth was a great delta, and its lower course ran through wide green and fertile lands, little peopled save by birds and beasts because of the Orc-raids; but they were not inhabited by Orcs, who preferred the northern woods, and feared the power of Ylmir – for Sirion’s mouth was in the Western Seas.
Turgon Fingolfin’s son had a sister Isfin. She was lost in Taur-na-Fuin after the Battle of Unnumbered Tears. There she was trapped by the Dark Elf Eöl. Their son was Meglin. The people of Turgon escaping aided by the prowess of Húrin were lost from the knowledge of Morgoth, and indeed of all in the world save Ylmir. In a secret place in the hills their scouts climbing to the tops discovered a broad valley entirely encircled by the hills in rings ever lower as they came towards the centre. Amid this ring was a wide land without hills, except for one rocky hill that stuck up from the plain, not right at the centre, but nearest to that part of the outer wall which marched close to the edge of Sirion.1
Ylmir’s messages come up Sirion bidding them take refuge in this valley, and teaching them spells of enchantment to place upon all the hills about, to keep off foes and spies. He foretells that their fortress shall stand longest of all the refuges of the Elves against Morgoth, and like Doriath never be overthrown – save by treachery from within. The spells are strongest near to Sirion, although here the encircling mountains are lowest. Here the Gnomes dig a mighty winding tunnel under the roots of the mountains, that issues at last in the Guarded Plain. Its outer entrance is guarded by the spells of Ylmir; its inner is watched unceasingly by the Gnomes. It is set there in case those within ever need to escape, and as a way of more rapid exit from the valley for scouts, wanderers, and messages, and also as an entrance for fugitives escaping from Morgoth.
Thorndor King of Eagles removes his eyries to the Northern heights of the encircling mountains and guards them against Orc-spies.2 On the rocky hill, Amon Gwareth, the hill of watching, whose sides they polish to the smoothness of glass, and whose top they level, the great city of Gondolin with gates of steel is built. The plain all about is levelled as flat and smooth as a lawn of clipped grass to the feet of the hills, so that nothing can creep over it unawares. The people of Gondolin grows mighty, and their armouries are filled with weapons. But Turgon does not march to the aid of Nargothrond, or Doriath, and after the slaying of Dior he has no more to do with the son of Fëanor (Maglor).3 Finally he closes the vale to all fugitives, and forbids the folk of Gondolin to leave the valley. Gondolin is the only stronghold of the Elves left. Morgoth has not forgotten Turgon, but his search is in vain. Nargothrond is destroyed; Doriath desolate; Húrin’s children dead; and only scattered and fugitive Elves, Gnomes and Ilkorins, left, except such as work in the smithies and mines in great numbers. His triumph is nearly complete.
1 Added here roughly in pencil: The hill nearest to Angband was guarded by Fingolfin’s cairn (cf. note 2).
2 Added here at the same time as the addition given in note 1: sitting upon Fingolfin’s cairn.
3 the son of Fëanor (Maglor) > the sons of Fëanor (this goes with the change at the end of §14, note 4).
Meglin son of Eöl and Isfin sister of Turgon was sent by his mother to Gondolin, and there received,1 although half of Ilkorin blood, and treated as a prince.
Húrin of Hithlum had a brother Huor. The son of Huor was Tuor, younger than Túrin2 son of Húrin. Rían, Huor’s wife, sought her husband’s body among the slain on the field of Unnumbered Tears, and died there. Her son remaining in Hithlum fell into the hands of the faithless men whom Morgoth drove into Hithlum after that battle, and he was made a thrall. Growing wild and rough he fled into the woods, and became an outlaw, and a solitary, living alone and communing with none save rarely with wandering and hidden Elves. On a time Ylmir contrived that he should be led to a subterranean river-course leading out of Mithrim into a chasmed river that flowed at last into the Western Sea. In this way his going was unmarked by Man, Orc, or spy, and unknown of Morgoth. After long wanderings down the western shores he came to the mouths of Sirion, and there fell in with the Gnome Bronweg, who had once been in Gondolin. They journey secretly up Sirion together. Tuor lingers long in the sweet land Nan Tathrin ‘Valley of Willows’; but there Ylmir himself comes up the river to visit him, and tells him of his mission. He is to bid Turgon prepare for battle against Morgoth; for Ylmir will turn the hearts of the Valar to forgive the Gnomes and send them succour. If Turgon will do this, the battle will be terrible, but the race of Orcs will perish and will not in after ages trouble Elves and Men. If not, the people of Gondolin are to prepare for flight to Sirion’s mouth, where Ylmir will aid them to build a fleet and guide them back to Valinor. If Turgon does Ylmir’s will Tuor is to abide a while in Gondolin and then go back to Hithlum with a force of Gnomes and draw Men once more into alliance with the Elves, for ‘without Men the Elves shall not prevail against the Orcs and Balrogs’. This Ylmir does because he knows that ere seven3 full years are passed the doom of Gondolin will come through Meglin.4
Tuor and Bronweg reach the secret way,5 and come out upon the guarded plain. Taken captive by the watch they are led before Turgon. Turgon is grown old6 and very mighty and proud, and Gondolin so fair and beautiful, and its people so proud of it and confident in its secret and impregnable strength, that the king and most of the people do not wish to trouble about the Gnomes and Elves without, or care for Men, nor do they long any more for Valinor. Meglin approving, the king rejects Tuor’s message in spite of the words of Idril the far-sighted (also called Idril Silver-foot, because she loved to walk barefoot) his daughter, and the wiser of his counsellors. Tuor lives on in Gondolin, and becomes a great chieftain. After three years he weds Idril – Tuor and Beren alone of all mortals ever wedded Elves, and since Elwing daughter of Dior Beren’s son wedded Eärendel son of Tuor and Idril of them alone has come the strain of Elfinesse into mortal blood.
Not long after this Meglin going far afield over the mountains is taken by Orcs, and purchases his life when taken to Angband by revealing Gondolin and its secrets. Morgoth promises him the lordship of Gondolin, and possession of Idril. Lust for Idril led him the easier to his treachery, and added to his hatred of Tuor.
Morgoth sends him back to Gondolin. Eärendel is born, having the beauty and light and wisdom of Elfinesse, the hardihood and strength of Men, and the longing for the sea which captured Tuor and held him for ever when Ylmir spoke to him in the Land of Willows.
At last Morgoth is ready, and the attack is made on Gondolin with dragons, Balrogs, and Orcs. After a dreadful fight about the walls the city is stormed, and Turgon perishes with many of the most noble in the last fight in the great square. Tuor rescues Idril and Eärendel from Meglin, and hurls him from the battlements. He then leads the remnant of the people of Gondolin down a secret tunnel previously made by Idril’s advice which comes out far in the North of the plain. Those who would not come with him but fled to the old way of escape are caught by the dragon sent by Morgoth to watch that exit.
In the fume of the burning Tuor leads his company into the mountains into the cold pass of Cristhorn (Eagles’ Cleft). There they are ambushed, but saved by the valour of Glorfindel (chief of the house of the Golden Flower of Gondolin, who dies in a duel with a Balrog upon a pinnacle) and the intervention of Thorndor. The remnant reaches Sirion and journeys to the land at its mouth – the Waters of Sirion. Morgoth’s triumph is now complete.
