My companion suddenly caught hold of my arm and we both jumped up the bank at the side of the road to let a long string of artillery drivers trot past on their way back for more ammunition. Another cloud of dust, and coming up behind us was a fresh lot of shells on the way out to the firing line. Right up in the sky ahead suddenly appeared a ball of yellow greeny smoke, which grew bigger and bigger, and then "boom" came the sound of a gun about three seconds afterward. A shell had burst in the air about 300 yards away. Another and another came--all about the same place. They appeared to come from the direction of Bapaume. "Bad, very bad," commented my companion. And so it appeared to me, for the Germans were dropping their shells from the southeast, at least one kilometer over range. We were standing beside a strawstack and looking due south, watching the just discernible line of French guns, when we heard the ominous whistling screech of an approaching shell. Down on our faces behind the stack, down we went like lightning, and over to the left, not 200 yards away, rose a huge column of black smoke and earth, and just afterward a very loud boom. A big German gun had come into action, slightly nearer this time. Just behind a wood I could plainly see the smoke of the gun itself rising above the trees. Two more shells from the big gun exploded within twenty yards of each other, and then, with disconcerting suddenness, a French battery came into action within a hundred yards of our strawstack cover. They had evidently been there for some time, awaiting eventualities, for we had no suspicion of their proximity, and they were completely hidden. My ears are still tingling and buzzing from the sound of those guns. One after another the guns of this battery bombarded the newly taken up position of the German big guns, which replied with one shell every three minutes. Presently we had the satisfaction of hearing a violent explosion in the wood, and a column of smoke and flame rose up to a great height. Soixante-quinze had again scored, for the German guns had been put out of action. From out the French position came infantry, at this point thousands of little dots over the landscape, presenting a front of, I should think, about two miles, rapidly advancing in skirmishing order. Every now and then the sharp crackle of rifle fire could distinctly be heard. The French had advanced over a mile, and the Germans had hastily evacuated the wood. Other French batteries now came into action, and the German fire over the whole arc was becoming decidedly fainter and less frequent. This might, of course, be due to changing their positions on the German front. Wounded began to arrive, which showed that for the present at any rate, it was safe to go out to the trenches to collect them.
