Battle of Dagorlad

The decisive battle of the War of the Last Alliance, in which the last great alliance of Elves and Men, led by Gil-galad and Elendil, faced the forces of Sauron. The Battle took place on a wide and dusty plain before the entrance to Mordor, and many who took part were lost in the marshes that bordered the battlefield on the west. There was great loss on either side, but Sauron was defeated and fled back to Barad-dûr. After the Battle was won came another seven long and bitter years of siege, but Sauron was finally defeated and the Second Age came to an end.

The Battle of Dagorlad was one of the greatest Middle-earth had ever seen. The original name of the field where it took place - if it had one - is now forgotten: that region was known afterwards simply as Dagorlad, 'Battle Plain'.
