I wished my new comrades good-night as I left the room, and I repeated that I should hold myself at their disposal at five o'clock next morning. They bowed in silence, and I thought that I could see from the expression of their faces that they had already begun to take a more just view of my character.

I had expected that the colonel would at once inform me what it was that I had been chosen to do, but instead of that he walked on in silence, I following behind him.

We passed through the camp and made our way across the trenches and over the ruined heaps of stones which marked the old wall of the town. Within, there was a labyrinth of passages formed among the debris of the houses which had been destroyed by the mines of the engineers. Acres and acres were covered with splintered walls and piles of brick which had once been a populous suburb. Lanes had been driven through it and lanterns placed at the corners with inscriptions to direct the wayfarer. The colonel hurried onward until at last, after a long walk, we found our way barred by a high grey wall which stretched right across our path.

Here behind a barricade lay our advance guard. The colonel led me into a roofless house, and there I found two general officers, a map stretched over a drum in front of them, they kneeling beside it and examining it carefully by the light of a lantern. The one with the clean-shaven face and the twisted neck was Marshal Lannes, the other was General Razout, the head of the engineers.

“Captain Gerard has volunteered to go,” said the colonel.

Marshal Lannes rose from his knees and shook me by the hand.

“You are a brave man, sir,” said he. “I have a present to make to you,” he added, handing me a very tiny glass tube. “It has been specially prepared by Dr. Fardet. At the supreme moment you have but to put it to your lips and you will be dead in an instant.”

This was a cheerful beginning. I will confess to you, my friends, that a cold chill passed up my back and my hair rose upon my head.

“Excuse me, sir,” said I, as I saluted, “I am aware that I have volunteered for a service of great danger, but the exact details have not yet been given to me.”

“Colonel Perrin,” said Lannes, severely, “it is unfair to allow this brave officer to volunteer before he has learned what the perils are to which he will be exposed.”
