Then Fingolfin beheld (as it seemed to him)
the utter ruin of the Noldor,
and the defeat beyond redress
of all their houses;
and filled with wrath and despair
he mounted Rochallor his great horse
and rode forth alone, and none might restrain him.
He passed over Dor-nu-Fauglith
like a wind amid the dust,
and all that beheld his onset fled in amaze,
thinking Orome himself was come;
for a great madness of rage was upon him,
so that his eyes shone like the eyes of the Valar.
Thus he came alone to Angband's gates,
and he sounded his horn,
and smote once upon the brazen doors,
and challenged Morgoth
to come forth to single combat.

The Orcs made no boast of that duel at the gate;
neither do the Elves sing of it,
for their sorrow is too deep.
