We learned the truth from some passing foot-soldiers. The Germans had entrenched themselves strongly on the wooded hills and in the quarries. The pursuit was held up, and a new battle was about to begin.
I asked a sergeant:
"But those aren't the Germans we were on the heels of yesterday and the day before, are they?"
"No," he answered, "these must be troops which were behind them in Belgium."
The first line, installed in a narrow valley, replenished every half-hour the battery which, in position near a large farm, was emptying wagonful after wagonful of shells. The German artillery swept the plain, and some six-inch Howitzers, whose objective seemed to be the bend of a neighbouring road, aiming too high, threatened to catch us in enfilading fire at any moment. On the other hand, one of their 77 mm. batteries had opened fire on a wood commanding the other end of the valley. There could be no thought of trying to get out of this uncomfortable position by way of the plain. The enemy would see us and his Howitzers would reach us with ease. The officer in charge of the train, Lieutenant Boutroux, was perplexed. Finally he decided to face the 77 mm. guns, and we began to work round the edge of the wood, shrapnel shell bursting over our heads. Soon the valley curved inwards. The danger zone was passed. Unscathed, and keeping well screened from the enemy, we took up a fresh position in another gully almost exactly similar to that we had just left.
We lacked water, and in order to find it had to follow a path leading across the field to some barns, from the roofs of which pipes ran down into a couple of water-tanks. A ladder was propped up against one of the latter, and I climbed up out of curiosity. The metal plating of the inside was covered with rust, and out of the turbid water, which was slowly sinking, emerged an old boot, a felt cap, and all sorts of shapeless objects of cloth or metal, coated with green slime. We had nevertheless to content ourselves with this water!...
The sound of the battle was indicative of no decision; it neither approached nor became fainter. The wounded who passed told us that since the morning the infantry had been continually launched against the strong entrenchments without being able to break through them. The gun-fire did not slacken until nightfall.
We rejoined the batteries, cutting across the plain now hidden from the enemy by the falling darkness. Somewhere a machine-gun was still crackling. A thin rain was floating in the air and we rapidly became wet through. We had to lie in the open among the mangel-wurzels, and the horses were not taken out of the vehicles.
It was almost impossible to sleep. The moment we lay still we began to shiver and our teeth chattered. I had a vague fear that the cold, which ran down my spine in long shudders, might kill me unawares if I went to sleep.
