He was High King of the Ñoldor in Middle-earth during the First Age after the death of his father. He was an instrument in healing the rift between the Sons of Fëanor and the followers of his father after their desertion of them in Araman.Fingon's final battle was the Nirnaeth Arnoediad (Battle of Unnumbered Tears). Fingon led the attack on Angband, and the fury of his warriors nearly won the day. Unfortunately, due to Ulfang's treachery, Maedhros did not arrive until three days after he was expected. This resulted in Morgoth releasing his Balrogs and Glaurung the dragon on the already weakened Ñoldor force. When Maedhros finally arrived, hope was reborn for Fingon's army; however, Ulfang's treachery again took effect, causing Maedhros to withdraw. Fingon was then surrounded and his guards killed. He dueled Gothmog, lord of Balrogs, but was struck from behind by another. Gothmog then clove Fingon's helm, and fire sprang from it. This presumably killed Fingon instantly, but the Balrogs proceeded to beat his body into the dust long after he was dead. Thus the day ended in defeat for the elves.
