During the War of Wrath, Eärendil came out of the west in Vingilot, accompanied by the Eagles of Manwë, and they fought with Ancalagon and the other dragons. Eventually, Eärendil was victorious, throwing Ancalagon upon Thangorodrim and destroying its towers. The fall of Ancalagon marked the end of Morgoth's final resistance.
Gandalf spoke of him as he told Frodo the true origin of his Ring. "It has been said that dragon-fire could melt and consume the Rings of Power, but there is not now any dragon left on earth in which the old fire is hot enough; nor was there ever any dragon, not even Ancalagon the Black, who could have harmed the One Ring, the Ruling Ring, for that was made by Sauron himself."
The Old English translation for Ancalagon is Andracca from and- ("opposition"), anda ("hatred, envy"), and draca ("dragon").
Ancalagon's size is not specified, but it is evident that he is gigantic due to destroying the towers of Thangorodrim, which are also identified as the three smoking peaks of the mountain.
- How Eärendil and other reinforcements including great eagles managed to slay Ancalagon and his kin is logically unknown as simply speaking, there were huge differences in size and war potential between the dragons and the eagles. This was true even for Thorondor, the greatest Eagle of all time. Therefore, eagles and elves could most likely only have won against their draconic foes because of support or collaboration with the Host of the Valar.
- Gandalf might or might not have seen Ancalagon during the War of Wrath.
