Battle of the Morannon
In J. R. R. Tolkien's epic fantasy novel The Lord of the Rings, the Battle of the Morannon or the Battle of the Black Gate is the final confrontation in the War of the Ring. Gondor and its allies send a small army ostensibly to challenge Sauron at the entrance to his land of Mordor; he supposes that they have with them the One Ring and mean to use it to defeat him.
