After defeating the Orcs in the Dagor Aglareb, Fingolfin maintained the Siege of Angband for nearly 400 years. But the Siege was ended by Morgoth's sudden assaults in the Dagor Bragollach, and many peoples of Beleriand fled. When Fingolfin learned of this, and received false report that his allies had been routed on all fronts, he became filled with wrath and despair. He immediately took his horse Rochallor and sword Ringil, and rode alone to Angband. All enemies fled from him, fearing his anger, and mistaking him in his fury for Oromë, the Vala patron of hunters.
He smote the gates of Angband and challenged Morgoth to single combat. Though Morgoth feared Fingolfin (of all the Valar, Morgoth was the only one to know fear), he had to accept the challenge — or face shame in the eyes of his servants. Seven times Fingolfin wounded Morgoth and seven times Morgoth cried in pain, and seven times the host of Morgoth wailed in anguish, but he could not be slain for he was one of the Valar.
Whenever Morgoth attacked, Fingolfin would evade, avoiding Morgoth's weapon Grond as it would crack the ground. Eventually, however, Fingolfin grew weary and stumbled on a crater. Then Morgoth pinned Fingolfin with his foot, and killed him, but not before he, with his last act of defiance, hewed at Morgoth's foot. Morgoth, from thence forward, always walked with a limp. An enraged Morgoth sought to desecrate the body of the valiant king but Thorondor, Lord of Eagles flew down and raked Morgoth's eyes, and carried Fingolfin's body away to be placed on a cliff overlooking Gondolin. Later his son Turgon built a cairn over the remains of his father.
