After that affair of the hill-crest we had a lot of trench work, and very harassing it was. For five days we stayed in trenches, so near to the enemy that it was death to show your head. Trench fighting is one of the most terrible features of the war, for not only is there the constant peril of instant death, which, of course, every soldier gets accustomed to, but there is also the extreme discomfort and danger of illness arising from insanitary surroundings. Often enough, too, when a new trench was being dug we would find that we were working on ground that had been previously occupied, and the spades brought up many a ghastly reminder of an earlier fight. Sometimes in this wonderful warfare we were so very close to the Germans that when we sang hymns--and many a hymn that a soldier has sung at his mother’s knee has gone up from the trenches from many a brave lad who has given his life for his country--the Germans would harmonise with them. It was strange to hear these men singing like that and to bear in mind that they were the soldiers who had done such monstrous things as we saw during the retreat, when they thought that certain victory was theirs. Time after time, with my own eyes, I saw evidence of the brutal outrages of the German troops, especially on women and children, yet it seems hard to convince some of the people at home that these things have been done. At one time in the trenches, for a whole week, we were so situated that we dare not even speak for fear of revealing our position--we were subjected to an enfilade fire and did not dare to speak or light a fire, which meant that we had no hot food for a week, and we could not even smoke, which was the biggest hardship of all for a lot of the lads. We were thankful when we were relieved; but were sorry indeed to find how dearly the newcomers paid for their experience. We had been cramped and uncomfortable, but pretty safe, and the Germans had not been able to get at us to do us any real mischief, but our reliefs walked about as unconcernedly as if they were on furlough, with the result that on the very first night they went into action they lost a hundred men. The system of trenches grew into a sort of enormous gridiron, and if you walked about--which you could only attempt to do at night--you were almost certain to drop into a trench or a hole of some sort. This made getting about a very exciting job, and it added enormously to the intense strain of fighting in the trenches, a strain which was hardest to bear in the night-time, when we were constantly expecting attacks and when the Germans adopted all kinds of devices to get at us.
