Battle of Gondolin

The Battle of Gondolin was a terrible battle of the First Age in which King Turgon, the last son of Fingolfin was slain. From the Fall of Gondolin, rose the Host of Valinor--as Tuor led the survivors out of Gondolin and to the Mouths of Sirion--there Earendil would grow up and eventually earn the Valar's protection for Ea against Morgoth.

At this battle, Gothmog and Raumo (the Balrog Glorfindel faced) were killed by Ecthelion and Glorfindel respectively, but died in the process. Eglamoth, Galdor, Voronwe, Celebrimbor, Tuor, Idril, and presumably Aranwe, managed to escape the Fall of Gondolin.

Tuor personally slew the four orc generals Balcmeg, Othrod, Lug, and Orcobol--and he managed to kill Maeglin. Tuor also wounded the Beast of Gondolin in this battle as well, and he fought through many evil fiery spirits too.

Rog slew many fire spirits, but eventually met his end to the remaining Balrog chieftains (probably slain by Lungorthin). Duiluin met his end (presumably) from a fiery bolt by Felagrog, who would later be known as Durin's Bane.

Among the evil survivors to fight in the War of Wrath were: Lungorthin, Uru, Durlach, Felagrog, Maroch, Salgant, and possibly the Beast of Gondolin, as he went into a berserk rage after being wounded by Tuor.
