These are all by Gen. George S. Patton.
"No bastard ever won a war by dying for his country. He won it by making the other poor dumb bastard die for his country."
“It is absurd to believe that soldiers who cannot be made to wear the proper uniform can be induced to move forward in battle. Officers who fail to perform their duty by correcting small violations and in enforcing proper conduct are incapable of leading.”
“You cannot be disciplined in great things and indiscipline in small things. Brave undisciplined men have no chance against the discipline and valour of other men. Have you ever seen a few policemen handle a crowd?”
"If a man does his best, what else is there?"
"Accept the challenges so that you can feel the exhilaration of victory."
"Success is how high you bounce when you hit bottom."
"Lead me, follow me, or get out of my way."
"Wars may be fought with weapons, but they are won by men."
"We want to get the hell over there. The quicker we clean up this Goddamned mess, the quicker we can take a little jaunt against the purple pissing Japs and clean out their nest, too. Before the Goddamned Marines get all of the credit."
"Sure, we want to go home. We want this war over with. The quickest way to get it over with is to go get the bastards who started it. The quicker they are whipped, the quicker we can go home. The shortest way home is through Berlin and Tokyo. And when we get to Berlin, I am personally going to shoot that paper hanging son-of-a-bitch Hitler. Just like I'd shoot a snake!"
"You're never beaten until you admit it."
"A pint of sweat will save a gallon of blood."
"Perpetual peace is a futile dream."
"It is foolish and wrong to mourn the men who died. Rather we should thank God that such men lived."
"Audacity, audacity, always audacity."
"Magnificent! Compared to war all other forms of human endeavor shrink to insignificance. God help me, I do love it so!"
My personal favorite, which I write on nearly everything...
"Nemo Me Impune Lacessit" --- Do Not Provoke Me With Impunity
-From The Cask of Amontillado by Edgar Allen Poe.
