§ Of the Voyage of Eärendil and the War of Wrath The Silmarillion

Yet it is said that Morgoth looked not for the assault that came upon him from the West; for so great was his pride become that he deemed that none would ever again come with open war against him. Moreover he thought that he had for ever estranged the Noldor from the Lords of the West, and that content in their blissful realm the Valar would heed no more his kingdom in the world without; for to him that is pitiless the deeds of pity are ever strange and beyond reckoning. But the host of the Valar prepared for battle; and beneath their white banners marched the Vanyar, the people of Ingwë, and those also of the Noldor who never departed from Valinor, whose leader was Finarfin the son of Finwë. Few of the Teleri were willing to go forth to war, for they remembered the slaying at the Swan-haven, and the rape of their ships; but they hearkened to Elwing, who was the daughter of Dior Eluchíl and come of their own kindred, and they sent mariners enough to sail the ships that bore the host of Valinor east over the sea. Yet they stayed aboard their vessels, and none of them set foot upon the Hither Lands.
