If you're referring to the Pelennor, notice that dawn broke and the Darkness was blown away, and the battle was fought in daylight. Note in particular that after the initial charge of Theoden, all the named enemies appear to be Men, not orcs or trolls- seemingly, all the Night Creatures were neutralized like Dracula when the sun came out.
