In The Lord of the Rings: The Return of the King, what is the name of the battle fought before Minas Tirith?

The battle fought before Minas Tirith in The Lord of the Rings: The Return of the King is the Battle of the Pelennor Fields.

Sauron’s armies attack Gondor’s capital after besieging Minas Tirith. The battle becomes the largest military confrontation shown in the film trilogy, involving Gondorian defenders, forces from Mordor, the Rohirrim, and the Army of the Dead.

Théoden leads the charge of the Rohirrim, but the Witch-king kills him before Éowyn and Merry defeat the Nazgûl lord. Aragorn later arrives with reinforcements from the Paths of the Dead. The battle is sometimes confused with the Battle of the Black Gate, which occurs later as a diversion while Frodo and Sam approach Mount Doom.
