The Siege of Utumno was an assault by the hosts of Valinor to destroy the ancient fortress of Melkor, Utumno. The battle took place at the Gates of Utumno, and as the battle wore on for years, the hosts of Aman were finally able to drive Melkor to the lowest parts of his fortress, where Tulkas and Melkor fought. Melkor was subdued and cast down by Tulkas, and was later taken back to the Halls of Mandos in Valinor, to be judged by Manwë. After the battle, Utumno was laid waste and the servants of Melkor escaped.
