§ Of the Fifth Battle: Nirnaeth Arnoediad The Silmarillion

On the appointed day, on the morning of Midsummer, the trumpets of the Eldar greeted the rising of the sun; and in the east was raised the standard of the sons of Fëanor, and in the west the standard of Fingon, High King of the Noldor. Then Fingon looked out from the walls of Eithel Sirion, and his host was arrayed in the valleys and the woods upon the east of Ered Wethrin, well hid from the eyes of the Enemy; but he knew that it was very great. For there all the Noldor of Hithlum were assembled, together with Elves of the Falas and Gwindor's company from Nargothrond, and he had great strength of Men: upon the right were the host of Dor-lómin and all the valour of Húrin and Huor his brother, and to them had come Haldir of Brethil with many men of the woods.
