“[Christopher:] You cannot conceive of the quantity of explosives the armies throw at each other for each man killed! The shells make a continuous noise, sometimes like an enormous machine breaking apart. At other times, they come whistling towards you in a thoughtful sort of way and then go crump and the screw cap flies off, hurtling through the air, screaming. There’s a kind of shell which comes with a crescendo like an express train, only faster. Another kind which makes a noise like tearing calico, louder and louder. The largest kind are the ones which burst in the sky and make a double crack, like a wet canvas being shaken out by a giant. Such immense explosions to kill such small, weak animals.”
