On a winter's night, Morgoth sent out rivers of flame from Thangorodrim, and the Mountains of Iron spewed fires and deadly fumes. The flames consumed the plain of Ard-galen, which was renamed Anfauglith. Many Elves perished as they tried to escape the fire, and the confusion caused by the flame and smoke hindered the defenders that watched Angband. Then Morgoth sent forth his armies, led by Glaurung, first of the Urulóki. Behind Glaurung came Balrogs and multitudes of Orcs, and they slaughtered anyone they came across. After a year of fighting, when Fingolfin, the High King of the Noldor, saw what he believed to be the utter ruin of the Noldor, he rode in anger across the dust of Anfauglith and challenged Morgoth to single combat. At the doors of Angband itself they fought a great duel. Fingolfin's sword, Ringil, wounded Morgoth seven times. Yet he was felled by Morgoth's hammer, Grond, and crushed by Morgoth's mighty foot. Fingolfin's body was saved by Thorondor King of Eagles and brought into the mountaintops north of Gondolin. There Turgon his son built a cairn over his body.
