The Silmarillion - J. R. R. Tolkien [93]
For nigh on two years after the Dagor Bragollach the Noldor still defended the western pass about the sources of Sirion, for the power of Ulmo was in that water, and Minas Tirith withstood the Orcs. But at length, after the fall of Fingolfin, Sauron, greatest and most terrible of the servants of Morgoth, who in the Sindarin tongue was named Gorthaur, came against Orodreth, the warden of the tower upon Tol Sirion.

And Morgoth sent out his spies, and they were clad in false forms and deceit was in their speech; they made lying promises of reward, and with cunning words sought to arouse fear and jealousy among the peoples, accusing their kings and chieftains of greed, and of treachery one
