The Battle of Dagorlad occurred in the year 3434 of the Second Age. It was fought between the army of the Last Alliance under Gil-galad and Elendil and an army of Orcs and other creatures loyal to Sauron. The battle took place on the great, treeless, open plain of Dagorlad, between the Dead Marshes and Cirith Gorgor.

THE WAR -

The united host of Elves and Men crossed the Misty Mountains and marched south through the vale of Anduin, where they were joined by the Silvan Elves led by Malgalad and Oropher, with a host from Khazad-dûm. The Alliance entered the vast plain near the Black Gate, where they were joined by Anárion's forces from the south, and confronted at last the black legions of Mordor. The Silvan Elves had little sympathy for the Sindar and Noldor that were led by Gil-galad. As a result, they were indisposed to place themselves under the supreme command of the High King of the Noldor.

THE AFTERMATH -

A great part of Sauron's soldiers were slain in this battle. The Alliance was able to enter Mordor, establish a camp upon the Plateau of Gorgoroth and lay the Siege of Barad-dûr itself. Nevertheless Sauron still had enough supplies to defend the fortress for seven more years, until the siege was so pressing that he himself came forth, which led to the battle on the slopes of Orodruin in which Sauron was defeated and the One Ring taken from him. Oropher's son Thranduil survived the war and established his reign over the Silvan Elves in the Woodland Realm. The slain were buried and their graves eventually were engulfed by the Dead Marshes. In the Third Age, the Dagorlad was the site of several battles between Gondor and various Easterling armies, and the climactic Battle of the Morannon.
