The Professor: War is hell, Mr. Thornhill, even when it's a cold one.

Paul Bäumer: Up at the front you're alive or you're dead and that's all. You can't fool anybody about that very long. And up there we know we're lost and done for whether we're dead or alive. Three years we've had of it, four years! And every day a year, and every night a century! And our bodies are earth, and our thoughts are clay, and we sleep and eat with death! And we're done for because you can't live that way and keep anything inside you!

Mueller: Listen, the sum of an arithmetic series is S = A + L times N over 2. Interesting, isn't it?
Katczinsky: What do you want to learn that stuff for...? One day you'll stop a bullet and it'll all be worthless.

Colonel Saito: Do not speak to me of rules. This is war! This is not a game of cricket!

Shears: You make me sick with your heroics! There's a stench of death about you. You carry it in your pack like the plague. Explosives and L-pills - they go well together, don't they? And with you it's just one thing or the other: destroy a bridge or destroy yourself. This is just a game, this war! You and Colonel Nicholson, you're two of a kind, crazy with courage. For what? How to die like a gentleman... how to die by the rules - when the only important thing is how to live like a human being.

Col. Nicholson: One day the war will be over. And I hope that the people that use this bridge in years to come will remember how it was built and who built it. Not a gang of slaves, but soldiers, British soldiers, Clipton, even in captivity.

Shears: I'd say the odds against a successful escape are about 100 to one. But may I add another word, Colonel? The odds against survival in this camp are even worse.

Markoff: I am Sergeant Markoff. I make soldiers out of scum like you, and I don't do it gently. You're the sloppiest looking lot I've ever seen. It's up to me to prevent you from becoming a disgrace to the Regiment. And I will prevent that if I have to kill half of you with work. But the half that lives will be soldiers. I promise you!

Markoff: (to a dead soldier he props on the wall The rest of the bullets you stop won't hurt as much as that first one.

Rhett Butler: Take a good look my dear. It's an historic moment you can tell your grandchildren about - how you watched the Old South fall one night.
