Which made it worse, because there was no cover. Tonight was moonless, but the landscape was occasionally lit by the flash of an explosion or the fierce bright light of a flare. All Walter could do then was fall flat and freeze. If he happened to be in a crater he might be hard to see. Otherwise he just had to hope no one was looking his way.
There were a lot of unexploded British shells on the ground. Walter calculated that something like a third of their ammunition was dud. He knew that Lloyd George had been put in charge of munitions, and guessed that the crowd-pleasing demagogue had prioritized volume over quality. Germans would never make such a mistake, he thought.
He reached the British wire, crawled laterally until he found a gap, and passed through.
As the British line began to appear, like the smear of a black paintbrush against a wash of dark gray sky, he dropped to his belly and tried to move silently. He had to get close: that was the point. He wanted to hear what the men in the trenches were saying.
Both sides sent out patrols every night. Walter usually dispatched a couple of bright-looking soldiers who were bored enough to relish an adventure, albeit a dangerous one. But sometimes he went himself, partly to show that he was willing to risk his own life, partly because his own observations were generally more detailed.
He listened, straining to hear a cough, a few muttered words, perhaps a fart followed by a sigh of satisfaction. He seemed to be in front of a quiet section. He turned left, crawled fifty yards, and stopped. Now he could hear an unfamiliar sound a bit like the hum of distant machinery.
He crawled on, trying hard to keep his bearings. It was easy to lose all sense of direction in the dark. One night, after a long crawl, he had come up against the barbed wire he had passed half an hour earlier, and realized he had gone around in a circle.
He heard a voice say quietly: “Over by here.” He froze. A masked flashlight bobbed into his field of view, like a firefly. In its faint reflected light he made out three soldiers in British-style steel helmets thirty yards away. He was tempted to roll away from them, but decided the movement was more likely to give him away. He drew his pistol: if he was going to die he would take some of the enemy with him. The safety catch was on the left side just above the grip. He thumbed it up and forward. It made a click that sounded to him like a thunderclap, but the British soldiers did not appear to hear it.
Two of them were carrying a roll of barbed wire. Walter guessed they were going to renew a section that had been flattened by German artillery during the day. Maybe I should shoot them quickly, he thought, one-two-three. They will try to kill me tomorrow. But he had more important work to do, and he refrained from pulling the trigger as he watched them go by and recede into darkness.
He thumbed back the safety catch, holstered his gun, and crawled closer to the British trench.
Now the noise was louder. He lay still for a moment, concentrating. It was the sound of a crowd. They were trying to be quiet, but men in the mass could always be heard. It was a sound formed of shuffling feet, rustling clothes, sniffing and yawning and belching. Over that there was the occasional quiet word spoken in a voice of authority.
But what intrigued and startled Walter was that it seemed such a big crowd. He could not estimate how many. Lately the British had dug new, broader trenches, as if to hold vast quantities of stores, or very large artillery pieces. But perhaps they were for crowds.
Walter had to see.
He crawled forward. The sound grew. He had to look inside the trench, but how could he do so without being seen himself?
He heard a voice behind him, and his heart stopped.
He turned and saw the glow-worm flashlight. The barbed-wire detail was returning. He pushed himself into the mud, then slowly drew his pistol.
They were hurrying, not troubling to be quiet, glad their task was done and keen to get back to safety. They came close, but did not look at him.
When they had passed, he was inspired, and leaped to his feet.
Now, if anyone should shine a light and see him, he would appear to be part of the group.
He followed them. He did not think they would hear his steps clearly enough to distinguish them from their own. None of them looked back.
He peered toward the source of the noise. He could see into the trench, now, but at first he could make out only a few points of light, presumably flashlights. But his eyes gradually adjusted, and at last he worked out what he was seeing, and then he was astonished.
He was looking at thousands of men.
