Siege of Eregion

The Siege of Eregion was a deadly battle between Sauron and the Elves of Eregion during the Second Age, marking the beginning of the War of the Elves and Sauron.
== History ==
The lord of Eregion, Celebrimbor, supervised the defense of the border of Eregion as he realized that Sauron was taking the route to the Fords of Isen. The High King Gil-galad sent Elrond to help Celebrimbor defend Eregion from Sauron. Elrond marched at the head of a small army, intending to confront Sauron at Ost-in-Edhil. But he arrived too late, as the city was in ruins. When the army arrived they were surprised at the fall of the city, and shocked by the death of Celebrimbor at the hands of Sauron. As such, they were quickly defeated by Sauron's forces. Elrond managed to retreat and build a fortress in a valley of the Misty Mountains called Rivendell.
