I'm sure somebody somewhere throughout history has said something similar, but my pre-game pep talk would be...

"Bulldogs! Ready your breakfast and eat hearty... For tonight, we dine in hell!
Give them nothing! But take from them everything!
The world will know that free Bulldogs stood against a tyrant, that few stood against many, and before this battle was over, even a god-king can bleed."

Now I gotta go find my shield and spear.
