from Unfinished Tales, Concerning Galadriel and Cirdan
When Sauron learned of the repentance and revolt of
Celebrimbor his disguise fell and his wrath was revealed; and gathering a great force he moved over Calenardhon (
Rohan) to the invasion of
Eriador in the year 1695. When news of this reached Gil-galad he sent out a force under Elrond
Half-elven; but Elrond had far to go, and Sauron turned north and made at once for Eregion. The scouts and vanguard of Sauron's host were already approaching when Celeborn made a sortie and drove them back; but though he was able to join his force to that of Elrond they could not return to Eregion, for Sauron's host was far greater than theirs, great enough both to hold them off and closely to invest Eregion. At last the attackers broke into Eregion with ruin and devastation, and captured the chief object of Sauron's assault, the House of the Mírdain, where were their smithies and their treasures. Celebrimbor, desperate, himself withstood Sauron on the steps of the great door of the Mírdain; but he was grappled and taken captive, and the House was ransacked. There Sauron took
the Nine Rings and other lesser works of the Mírdain; but the Seven and the Three he could not find. Then Celebrimbor was put to torment, and Sauron learned from him where the Seven were bestowed. This Celebrimbor revealed, because neither the Seven nor the Nine did he value as he valued the Three; the Seven and the Nine were made with Sauron's aid, whereas the Three were made by Celebrimbor alone, with a different power and purpose. [It is not actually said here that Sauron at this time took possession of the Seven Rings, though the implication seems clear that he did so. In Appendix A (III) to The Lord of the Rings it is said that there was a belief among the Dwarves of Durin's Folk that the Ring of Durin III, King of Khazad-dûm, was given to him by the Elven-smiths themselves, and nothing is said in the present text about the way in which the Seven Rings came into possession of the Dwarves.] Concerning the Three Rings Sauron could learn nothing from Celebrimbor; and he had him put to death. But he guessed the truth, that the Three had been committed to
Elvish guardians: and that must mean to Galadriel and Gil-galad.
In black anger he turned back to battle; and bearing as a banner Celebrimbor's body hung upon a pole, shot through with Orc-arrows, he turned upon the forces of Elrond. Elrond had gathered such a few of the
Elves of Eregion as had escaped, but he had no force to withstand the onset. He would indeed have been overwhelmed had not Sauron host been attacked in the rear; for
Durin sent out a force of Dwarves from
Khazad-dûm, and with them came Elves of
Lórinand led by
Amroth. Elrond was able to extricate himself, but he was forced away northwards, and it was at that time [in the year 1697, according to the Tale of Years] that he established a refuge and stronghold at
Imladris (
Rivendell). Sauron withdrew the pursuit of Elrond and turned upon the Dwarves and the Elves of Lórinand, whom he drove back; but the Gates of
Moria were shut, and he could not enter. Ever afterwards Moria had Sauron's hate, and all
Orcs were commanded to harry Dwarves whenever they might.
