To give a recipe for getting a rough idea, in case you want to, I recommend the following procedure. Select a flat ten-acre ploughed field, so sited that all the surface water of the surrounding country drains into it. Now cut a zig-zag slot about four feet deep and three feet wide diagonally across, dam off as much water as you can so as to leave about a hundred yards of squelchy mud; delve out a hole at one side of the slot, then endeavour to live there for a month on bully beef and damp biscuits, whilst a friend has instructions to fire at you with his Winchester every time you put your head above the surface.
Well, here I was, anyway, and the next thing was to make the best of it. As I have before said, these were the days of the earliest trenches in this war: days when we had none of those desirable "props," such as corrugated iron, floorboards, and sand bags ad lib.
When you made a dug-out in those days you made it out of anything you could find, and generally had to make it yourself. That first night I was "in" I discovered, after a humid hour or so, that our battalion wouldn't fit into the spaces left by the last one, and as regards dug-outs, the truth of that mathematical axiom, "Two's into one, won't go," suddenly dawned on me with painful clearness. I was faced with making a dug-out, and it was raining, of course. (Note.—Whenever I don't state the climatic conditions, read "raining.") After sloshing about in several primitive trenches in the vicinity of the spot where we had fixed our best machine-gun position, my sergeant and I discovered a sort of covered passage in a ditch in front of a communication trench. It was a sort of emergency exit back from a row of ramshackle, water-logged hovels in the ditch to the communication trench. We decided to make use of this passage, and arranged things in such a way that by scooping out the clay walls we made two caves, one behind the other. The front one was about five yards from the machine gun, and you reached the back cave by going through the outer one. It now being about 11 p.m., and having been for the last five hours perpetually on the scramble, through trenches of all sorts, I drew myself into the inner cave to go to sleep.
This little place was about 4 feet long, 3 feet high, and 3 feet wide. I got out my knife, took a scoop out of the clay wall, and fishing out a candle-end from my pocket, stuck it in the niche, lit it and a cigarette. I now lay down and tried to size up the situation and life in general.
Here I was, in this horrible clay cavity, somewhere in Belgium, miles and miles from home. Cold, wet through and covered with mud. This was the first day; and, so far as I could see, the future contained nothing but repetitions of the same thing, or worse.
Nothing was to be heard except the occasional crack of the sniper's shot, the dripping of the rain, and the low murmur of voices from the outer cave.
