The Eagles: First Age (p2)
Thorondor wounded Morgoth in the face after Morgoth's battle with Fingolfin, and carried Fingolfin's corpse to the Echoriath, where Turgon buried him.
The Great Eagles fought alongside the army of the Valar, Elves and Edain during the War of Wrath at the end of the First Age, intervening decisively with Eärendil in the battle against Ancalagon.
