After Eärendil, father of Elrond, made his journey to Valinor to convince the Valar to overthrow Morgoth and rescue the overmatched and defeated Elves and Edain, The Host of Valinor made war upon Morgoth and destroyed his armies. Facing final defeat, Morgoth unleashed his last and greatest weapon; a fleet of winged fire drakes, led by Ancalagon. So terrible was the onslaught of these new foes that the armies of the Valar were driven back from the gates of Angband, and their coming was said to have been accompanied by a tempest of fire and lightning. But Eärendil came out of the West in his blessed ship Vingilot, accompanied by the Eagles of Manwë led by Thorondor, their leader. The Eagles and Eärendil dueled with Ancalagon and the other dragons for an entire day. Eventually, Eärendil was victorious, casting Ancalagon down upon Thangorodrim and destroying the volcanic mountains in his fall. The death of Ancalagon marked the end of Morgoth's final resistance and Ancalagon's maker was then subdued and hauled away in chains to be consigned to the Void.
