"I see in your eyes... the same fear that would take the heart of me!
A day may come when the courage of men fails, when we forsake our friends and break all bonds of fellowship, but it is not this day!
An hour of wolves and shattered shields when the age of men comes crushing down...!
But it is not this day.This day we fight!"

Aragorn's speech at the Black Gate, Lord of The Rings II - Return of the King
