At length my companion broke the silence. "As Bosche seems to be going easy, and our artillery has shut up shop, let's lie down," and with that he threw himself on the bed. I sat on the box, which served as a table, smoking. Half an hour went by. Things were livening up a bit. We began to hum a tune or two from the latest revue. Suddenly we were brought to our feet by a crashing sound that was absolutely indescribable in its intensity. I rushed up the incline into the trench. What a sight! The whole of our front for the distance of a mile was one frightful inferno of fire. The concentration of artillery fire was terrific! Scores of star-shells shot into the air at the same moment, lighting the ground up like day, showing up the smoking, blazing mass more vividly than ever. Hundreds of shells, large and small, were bursting over our trenches simultaneously; our guns were replying on the German front with redoubled fury; the air was alive with whirling masses of metal. The noise was indescribable. The explosions seemed to petrify one. I made my way as near the front line as possible. A number of Scots rushed by me with a load of hand grenades. The trenches were packed with men rushing up to the fight. I asked an officer who raced by, breathlessly, if Bosche was getting through. "Yes," he yelled; "they are trying to get through in part of my section. They have smashed our communication trenches so much that I have got to take my men round on the right flank. It's hell there!" It was impossible to get through. The place was choked with men, many of them badly wounded; some of them, I'm afraid, destined as tenants of the little cemetery near by. The awful nightmare continued. Men were coming and going. Reserves were being rushed forward; more bombs were being sent up. The Bosche artillery quietened down a bit, but only, as I found out immediately afterwards, to allow their bombers to attack. I could see the flash of hundreds of bombs, each one possibly tearing the life out of some of our brave boys. Nothing in the world could have withstood such a concentrated artillery fire as the Germans put upon that five hundred yards of ground. It was torn and torn again, riven to shreds. It was like the vomiting of a volcano, a mass of earth soddened with the blood of the heroes who had tried to hold it. The Germans came on, bombing their way across to what was left of our trench. They dug themselves in. Then with a whirl and a crash, our guns spoke again. Our boys, who had been waiting like dogs on a leash, sprang to the attack. Briton met Bosche. The battle swayed first this way then that. Our men drove the Germans out twice during the night, and held on to a section commanding the flank of the original position. Towards four o'clock the fighting ceased. Daylight was breaking. The wounded were still being passed to the rear. I stopped and spoke to an officer. "How have you got on?" I asked.
