Okay, I will give it a second go:

FG-T-24 Then spake Tuor, and Ulmo set power in his heart and majesty in his voice. ‘Behold, O father of the City of Stone, I am bidden by him who maketh deep music in the Abyss, and who knoweth the mind of Elves and Men, to say unto thee that the days of Release draw nigh. There have come to the ears of Ulmo whispers of your{ dwelling and your hill of} vigilance against the evil of {Melko}[Melkor], and he is glad: but his heart is wroth and the hearts of the Valar are angered who sit in the mountains of Valinor and look upon the world from the peak of Taniquetil, seeing the sorrow of the thraldom of the {Noldoli}[Elves] and the wanderings of Men; for {Melko}[Melkor] ringeth them in the Land of Shadows beyond {hills of iron}[Ered Wethrin]. Therefore have I been brought by a secret way to bid you number your hosts and {prepare for battle, for the time is ripe.}’ <Q30 abandon Gondolin and lead {his}your people down Sirion>.' <Q30 Summons too should {he}Turgon send into the East and gather, if he might, Men (who were now multiplying and spreading on the earth) unto his banners; and for that task Tuor was most fit. 'Forget,' counselled Ulmo, 'the treachery of Uldor the accursed, and remember Hurin; for without mortal Men the Elves shall not prevail against the Balrogs and the Orcs.' Nor should the feud with the sons of Feanor be left unhealed; for this should be the last gathering of the hope of the {Gnomes}[Noldor], when every sword should count.> Thus <Q30 Tuor spoke the embassy of Ulmo <TO in the hearing of all>, and something of the power and majesty of the Lord of Waters his voice had caught, so that all folk looked in wonder on him, and doubted that this were a Man of mortal race as he declared.>
FG-T-25 Then spake Turgon: ‘That will I not do, though it be the words of Ulmo and all the Valar. I will not adventure this my people against the terror of the Orcs, nor emperil my city against {the fire of Melko}<editorial addition decline>.’
Then spake Tuor: ‘Nay, if thou dost not now dare greatly then will the Orcs dwell for ever and possess in the end most of the mountains of the Earth, and cease not to trouble both Elves and Men, even though by other means the Valar contrive hereafter to release the {Noldoli}[Noldor]; but if thou trust now to the Valar, though terrible the encounter, then shall the Orcs fall, and {Melko}[Melkor]'s power be minished to a little thing.’ <Q30 {and}And he foretold the healing of feuds, and friendship between Men and Elves, whereof the greatest good should come into the world, and the servants of Morgoth trouble it no more.>
But Turgon said that he was king of Gondolin and no will should force him against his counsel to emperil the dear labour of long ages gone; but Tuor said, for thus was he bidden by Ulmo who had feared the reluctance of Turgon: ‘Then am I bidden to say that men of the {Gondothlim}[Gondolindrim] repair swiftly and secretly down the river Sirion to the sea, and there build them boats and go seek back to Valinor: lo! the paths thereto are forgotten and the highways faded from the world, and the seas and mountains are about it, yet still dwell there the Elves on the hill of {Kôr}[Tuna] and the {Gods}[Valar] sit in Valinor, though their mirth is minished for sorrow{ and fear of Melko}, and they hide their land and weave about it inaccessible magic that no evil come to its shores. Yet still might thy messengers win there and turn their hearts that they rise in wrath and smite {Melko}[Melkor], and destroy the Hells of Iron that he has wrought beneath the Mountains of Darkness.’ <QS77 And he gave warning to Turgon that the Curse of Mandos now hastened to its fulfilment, when all the works of the Noldor should perish;> <TO {Ulmo's cloak would vanish when Tuor spoke the message to Turgon}[and when he had spoken, the cloak of Ulmo vanished.]>
<QS77 Then Turgon pondered long the counsel of Ulmo, and there came into his mind the words that were spoken to him in Vinyamar: 'Love not too well the work of thy hands and the devices of thy heart; and remember that the true hope of the Noldor lieth in the West, and cometh from the Sea.' But Turgon was become proud, and Gondolin as beautiful as a memory of Elven Tirion, and he trusted still in its secret and impregnable strength, though even a Vala should gainsay it; and after the Nirnaeth Arnoediad the people of that city desired never again to mingle in the woes of Elves and Men without, nor to return through dread and danger into the West. Shut behind their pathless and enchanted hills they suffered none to enter, though he fled from Morgoth hate-pursued; and tidings of the lands beyond came to them faint and far, and they heeded them little. The spies of Angband sought for them in vain; and their dwelling was as a rumour, and secret that none could find.>
Then said Turgon: ‘Every year at the lifting of winter have messengers repaired swiftly and by stealth down the river FG-T-26 {that is called} Sirion to the coasts of the Great Sea, and there builded them boats whereto have swans and gulls been harnessed or the strong wings of the wind, and these have sought back beyond the moon and sun to Valinor; but the paths thereto are forgotten and the highways faded from the world, and the seas and mountains are about it, and they that sit within in mirth reck little of the dread of {Melko}[Morgoth] or the sorrow of the world, but hide their land and weave about it inaccessible magic, that no tidings of evil come ever to their ears. Nay, enough of my people have for years untold gone out to the wide waters never to return, but have perished in the deep places or wander now lost in the shadows that have no paths; and at the coming of next year no more shall fare to the sea, but rather will we trust to ourselves and our city for the warding off of {Melko}[Morgoth]; and thereto have the Valar been of scant help aforetime.’

Then Tuor's heart was heavy, and Voronwë wept; ...

In this version Ulmo would beg Turgon to retreat to the mouth of Sirion and there gahter all strength for the war to come. Now Ulmo fortells that with the gathered sterngth of Turgon the war to come from the West would be much more then the actual War of Wrath in which the forces of Middle-Earth were very much reduced. This counsel would allow Eärendil to be real cause form Ulmos action, even so if Turgon would have followed at least one of Ulmos bidding his early viëta and later role might have been diffrent.
