War of Wrath
In Beleriand, Elwë was eventually found, and married Melian the Maia. He became the overlord of Beleriand, naming himself Thingol (Sindarin: "Grey-cloak"). After the First Battle of Beleriand, during the first rising of the Moon, the Noldor arrived in Beleriand. They laid a siege around Morgoth's fortress of Angband, but were eventually defeated. The Elves never regained the upper hand, finally losing the hidden kingdoms Nargothrond, Doriath, and Gondolin near the culmination of the war. When the Elves had been forced to the furthest southern reaches of Beleriand, Eärendil the Mariner, a half-elf from the House of Finwë, sailed to Valinor to ask the Valar for help. The Valar started the War of Wrath, finally defeating Morgoth.
