One midnight after a certain engagement "somewhere in France" in which many men fell, I learned of an experience which burned its way into my soul, and I believe will stay there till the Judgment Day. I have read in history of individuals such as the one I am telling of, but never in my life have I had actual knowledge of any but this one, and I hope that I shall hereafter forever be delivered from such.

This particular night the firing for some reason had suddenly ceased. A man named Valke was an emergency watcher at a listening post, when the most blood-curdling thing I have ever known occurred.

A listening post is a branch off from the main trench toward the enemy or in his general direction, which is dug secretly as you go, the dirt being carried back in bags so as not to disclose its location. These posts must be changed often, as the enemy is apt to discover them, and then look out!

Valke was standing in the darkness and seclusion of the post when a shriek rent the air, the sound of which he said he would hear through eternity. It came from a man who was prostrate on the ground. He had noticed the body lying there before, a few yards away, and had assumed that the man was dead. He was a Frenchman, and on account of the darkness could be seen with difficulty. But he was not dead, only unconscious, and something had suddenly revived him.

"O God," he cried, "my marriage ring!" and then he moaned and groaned like a lost soul in agony. Immediately another form raised up to full stature and looked quickly about. Valke had to strain his eyes to see him and he trembled with nervousness. He did not know what to do for an instant. The man's head jerked this way and that. He must have expected someone to hear the cries and groans of the other man, and evidently was looking around for watchers or listeners. The Frenchman kept on groaning, and the man, seeming to fear that if any watchers were near, they would immediately let loose upon him, started to run. Valke kept very still in his dark post.

Suddenly the fugitive stopped. He turned and ran back to the prostrate Frenchman. Valke saw the gleam of a knife drawn from a sheath. It was in the hand of the apache. In an instant the horrid thing was done—a swift movement of the arm, a flash, and the blade plunged into the body of the helpless soldier! Then silence: silence more terrible than the groans of agony that it stilled. Valke's fists clinched by instinct, the nails cutting into the very flesh of his palms; and then his right hand went to the holster on his hip. It was all too plain: the hideous vulture of the battlefield knew that "dead men tell no tales," and that the wounded sometimes recover and tell things that lead to fearful reprisals on their enemies. More than that: wounded men cry out and groan; but the dead are quiet. The knife had done its work: escape might be surer for the assassin. That's the logic of ghouls.

Valke drew his service pistol, but hesitated to fire. To do so might betray his listening post and draw the enemy's shrapnel; it might be fatal to the section. In the second that Valke cast up the chances, he heard whisperings from another listening post. The ghoul had risen and was slinking for cover when the crack of a rifle tore a gap in the stillness. A light flashed up fifty yards ahead. Instinctively, the prowler sought the cover of a bush nearby and waited for the lapse of attention which might let him dash to safety. A sentry on patrol came up, passed, and vanished. That was the apache's chance! He came out of hiding and skulked along the entanglements hoping to find an alleyway to safety. The way led him right in front of Valke's listening post. A flash lamp shot its beam of blinding light full on the assassin's face.

"Who goes there?" challenged Valke. No answer.

"Who goes there?" ... Silence; not a sound.

"Qui Vive?" ... No reply. "Qui Vive?" ...

Then Valke pressed the trigger and with a groan the apache crumpled up, dead.

"For a minute," said Valke in telling me the story, "the thought of what I had done made me shudder, though it was nothing but a plain matter of army duty. The man had been challenged, well knowing the penalty of war for silence. And yet—I had killed him! It made me feel faint. But when we examined the body it was all right again inside of me. That German held in his hand a bleeding human finger, still at blood heat, and around that finger was a marriage ring! In his pocket he had an emblem pin and a gold watch and chain; and on his own finger a diamond ring—all snatched from the dead or dying bodies of men who had made the supreme sacrifice for France! Who could pity such a vile ghoul as he?"

From that hour I believe my transformation began. I thought of my sacred calling, the ministry. My church at home flashed into my mind. What would people think? How would I stand in the eyes of God? I reflected on my former teachings and beliefs. Could I face my friends, to whom I had preached peace and gentleness, now that I had applauded violence and war? Was it right or justifiable? My mind was very much perturbed and I was extremely nervous. A process of moral regeneration of my ideas was going on. This, I now believe, to be as important as a man's spiritual conversion, and step by step this book unfolds the process in my life. I stood at an hour of decision. I faced life. Its issues must be met. Here in the presence of death I had my supreme struggle. Time divided! The roads parted. Eternity was ahead. Where was I? I was in hell! Right then it surrounded, enveloped, engulfed me. The hour was freighted with destiny. Then came a sudden high resolve. "I must take the path of right and duty, wherever it may lead, e'en 'though I walk through the valley of the shadow of death, Thou art with me.' Duty may require violence and war." My pacifism began to fade away, as I saw visions of mutilated men. Then all went black.
