First Battle of Beleriand

When Morgoth returned to his fortress of Angband--his servants Sauron and Gothmog had been continuing breeding orcs for their master. Morgoth immediately decided to secure the area quickly and decided to attack Doriath. He sent two forces out from Angband to attack Doriath. Doriath called for aid and the elves of Ossiriand answered. The elves managed to beat Morgoth's forces and pushed them towards Mount Dolmed, where the Dwarves wiped out the remnants of Angband's forces.

The western host of elves were led by Cirdan, while the eastern host of elves were led by King Elwe of Doriath. After this battle, Ossiriand elves promised to never have a king again as Denethor was slain, and the Girdle of Melian was set up to protect Doriath.
