War of the Elves and Sauron

The War of the Elves and Sauron was a great war fought in the mid-Second Age in Middle-earth.

History
The war began in SA 1693, almost a century after Sauron had deceived the Ñoldor of Eregion and had forged the One Ring, deceiving and claiming all the Rings of Power from the fortress Ost-in-Edhil, except the Three Rings of the Elves.

Messages of this betrayal were sent north to Lindon where the High King Gil-galad ruled, and he began amassing his forces, preparing for an invasion. He also called for help from Númenor.

In SA 1695 Sauron attacked most of them make a past to the Fords of Isen the Siege of Eregion has begun, and Elrond was sent to Eregion by Gil-galad. However, in SA 1697 Eregion was laid waste. Celebrimbor, Lord of Eregion, was killed, and Khazad-dûm's gates were closed. Elrond fled north with the survivors, founding Imladris (Rivendell).

By SA 1699 all of Eriador fell under Sauron's control, and he set fire to the great forests in Enedwaith and Minhiriath to drive off the Elves and their allies (Edain). Imladris was besieged, and Lindon cut off from Imladris and Khazad-dûm.

The next year a great army of Númenor arrived, sent by Tar-Minastir and commanded by Ciryatur, which landed in Lindon, at Tharbad on the Gwathló, and south near Pelargir. Sauron's forces were caught in between the armies, and destroyed. The war ended in SA 1701 when Sauron retreated to the east, but Eregion was gone, and most of Eriador destroyed.
