He was conscious that General Vaugirard was still going forward along the long white road, sweeping his glasses from left to right and from right to left in a continuous semi-circle, apparently undisturbed, apparently now without human emotion. He was no figure of romance, but he was a man, cool and powerful, ready to die with all his men, if death for them was needed.

Still the invisible hand swept them on, the hand that a million men in action could not see, but which every one of the million, in his own way, felt. The crash of the guns on both sides had become fused together into one roar, so steady and continued so long that the sound seemed almost normal. Voices could now be heard under it and John spoke to de Rougemont.

"Can you make anything of it?" he asked. "Do we win or do we lose?"

"It's too early yet to tell anything. The cannon only are speaking, but you'll note that our army is advancing."

"Yes, I see it. Before I've only beheld it in retreat before overwhelming numbers. This is different."

General Vaugirard beckoned to his aides, and again sent them out with messages. John's note was to the commander of a battery of field guns telling him to move further forward. He started at once through the fields on his motor cycle, but he could not go fast now. The ground had been cut deep by artillery and cavalry and torn by shells and he had to pick his way, while the shower of steel, sent by men who were firing by mathematics, swept over and about him.

Shivers seized him more than once, as shrapnel and pieces of shell flew by. Now and then he covered his eyes with one hand to shut out the horror of dead and torn men lying on either side of his path, but in spite of the shells, in spite of the deadly nausea that assailed him at times, he went on. The rush of air from a shell threw him once from his motor cycle, but as he fell on soft clodded earth he was not hurt, and, springing quickly back on his wheel, he reached the battery.

The order was welcome to the commander of the guns, who was anxious to go closer, and, limbering up, he advanced as rapidly as weapons of such great weight could be dragged across the fields. John followed, that he might report the result. They were now facing toward the east and the whole horizon there was a blaze of fire. The shells were coming thicker and thicker, and the air was filled with the screaming of the shrapnel.

The commander of the battery, a short, powerful Frenchman, was as cool as ice, and John drew coolness from him. One can get used to almost anything, and his nervous tremors were passing. Despite the terrible fire of the German artillery the French army was still advancing. Many thousands had fallen already before the shells and shrapnel of the invisible foe, but there had been no check.

The cannon crossed a brook, and, unlimbering, again opened a tremendous fire. To one side and on a hill here, a man whom the commander watched closely was signaling. John knew that he was directing the aim of the battery and the French, like the Germans, were killing by mathematics.
