When the aëroplanes are home and the sunset has flared away, and it is cold, and night comes down over France, you notice the guns more than you do by day, or else they are actually more active then, I do not know which it is.  
It is then as though a herd of giants, things of enormous height, came out from lairs in the earth and began to play with the hills. It is as though they picked up the tops of the hills in their hands and then let them drop rather slowly. It is exactly like hills falling. You see the flashes all along the sky, and then that lumping thump as though the top of the hill had been let drop, not all in one piece, but crumbled a little as it would drop from your hands if you were three hundred feet high and were fooling about in the night, spoiling what it had taken so long to make. That is heavy stuff bursting, a little way off.
 
If you are anywhere near a shell that is bursting, you can hear in it a curious metallic ring. That applies to the shells of either side, provided that you are near enough, though usually of course it is the hostile shell and not your own that you are nearest to, and so one distinguishes them. It is curious, after such a colossal event as this explosion must be in the life of a bar of steel, that anything should remain at all of the old bell-like voice of the metal, but it appears to, if you listen attentively; it is perhaps its last remonstrance before leaving its shape and going back to rust in the earth again for ages.
 
Another of the voices of the night is the whine the shell makes in coming; it is not unlike the cry the hyena utters as soon as it’s dark in Africa: “How nice traveller would taste,” the hyena seems to say, and “I want dead White Man.” It is the rising note of the shell as it comes nearer, and its dying away when it has gone over, that make it reminiscent of the hyena’s method of diction. If it is not going over then it has something quite different to say. It begins the same as the other, it comes up, talking of the back areas with the same long whine as the other. I have heard old hands say “That one is going well over.” “Whee-oo,” says the shell; but just where the “oo” should be long drawn out and turn into the hy............
