The next day there was very heavy shelling at noon; shells were bracketing along our trench about five yards short and five yards over, but never quite getting it. We were having dinner and three times running my cup of tea was spilt by the concussion and filled with dirt. I was in a cheerful mood and only laughed. I had just had a parcel of kippers from home; they were far more important than the bombardment—I recalled with appreciation one of my mother’s sayings: ‘Children, remember this when you eat your kippers; kippers cost little, yet if they cost a hundred guineas a pair they would still find buyers among the millionaires.’ Before the shelling had started a tame magpie had come into the trench; it had apparently belonged to the Germans who had been driven out of the village by the Gordon Highlanders a day or two before. It was looking very draggled. ‘That’s one for sorrow,’ I said. The men swore that it spoke something in German as it came in, but I did not hear it. I was feeling tired and was off duty, so without waiting for the bombardment to stop I went to sleep in the trench. I decided that I would just as soon be killed asleep as awake. There were no dug-outs, of course. I always found it easy now to sleep through bombardments. I was conscious of the noise in my sleep, but I let it go by. Yet if anybody came to wake me for my watch or shouted ‘Stand-to!’ I was alert in a second. I had learned to go to sleep sitting down, standing up, marching, lying on a stone floor, or in any other position, at a moment’s notice at any time of day or night. But now I had a dreadful nightmare; it was as though somebody was handling me secretly, choosing the place to drive a knife into me. Finally, he gripped me in the small of the back. I woke up with a start, shouting, and punched the small of my back where the hand was. I found that I had killed a mouse that had been frightened by the bombardment and run down my neck. That afternoon the company got an order through from the brigade to build two cruciform strong-points at such-and-such a map reference. Moodie, the company commander, and I looked at our map and laughed. Moodie sent back a message that he would be glad to do so, but would require an artillery bombardment and strong reinforcements because the points selected, half way to Martinpuich, were occupied in force by the enemy. The colonel came up and verified this. He said that we should build the strong-point about three hundred yards forward and two hundred yards apart. So one platoon stayed behind in the trench and the other went out and started digging. A cruciform strong-point consisted of two trenches, each some thirty yards long, crossing at right angles to each other; it was wired all round, so that it looked, in diagram, like a hot-cross bun. The defenders could bring fire to bear against an attack from any direction. We were to hold each of these points with a Lewis gun and a platoon of men.
