'Then [Gothmog] turned upon Fingon. That was a grim meeting. At last Fingon stood alone with his guard dead about him; and he fought with Gothmog, until another Balrog came behind and cast a thong of fire about him. Then Gothmog hewed him with his black axe, and a white flame sprang up from the helm of Fingon as it was cloven. Thus fell the High King of the Noldor; and they beat him into the dust with their maces, and his banner, blue and silver, they trod into the mire of his blood.' - Of the Fifth Battle, The Silmarillion.
