"Sir," said I, "may I be permitted to make a suggestion?"

He looked at me with a hard eye. He had not forgotten my observations at supper. "Speak!" said he.

"I would point out, sir," said I, "that this mission is mine both by right and by convenience."

"Why so, Captain Gerard?"

"By right because I am the senior captain. By convenience because I shall not be missed in the regiments since the men have not yet learned to know me."

The colonel's features relaxed.

"There is certainly truth in what you say, Captain Gerard," said he. "I think that you are indeed best fitted to go upon this mission. If you will come with me I will give you your instructions."

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 pa.s.sed 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 pa.s.sages 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 gla.s.s 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 pa.s.sed 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."

But already I was myself once more.

"Sir," said I, "permit me to remark that the greater the danger the greater the glory, and that I could only repent of volunteering if I found that there were no risks to be run."

It was a n.o.ble speech, and my appearance gave force to my words. For the moment I was a heroic figure.

As I saw Lannes's eyes fixed in admiration upon my face it thrilled me to think how splendid was the debut which I was making in the army of Spain. If I died that night my name would not be forgotten. My new comrades and my old, divided in all else, would still have a point of union in their love and admiration of Etienne Gerard.

"General Razout, explain the situation!" said Lannes, briefly.

The engineer officer rose, his compa.s.ses in his hand.

He led me to the door and pointed to the high grey wall which towered up amongst the debris of the shattered houses.

"That is the enemy's present line of defence," said he. "It is the wall of the great Convent of the Madonna. If we can carry it the city must fall, but they have run countermines all round it, and the walls are so enormously thick that it would be an immense labour to breach it with artillery. We happen to know, however, that the enemy have a considerable store of powder in one of the lower chambers. If that could be exploded the way would be clear for us."

"How can it be reached?" I asked.

"I will explain. We have a French agent within the town named Hubert.

This brave man has been in constant communication with us, and he had promised to explode the magazine. It was to be done in the early morning, and for two days running we have had a storming party of a thousand Grenadiers waiting for the breach to be formed. But there has been no explosion, and for these two days we have had no communication from Hubert. The question is, what has become of him?"

"You wish me to go and see?"

"Precisely. Is he ill, or wounded, or dead? Shall we still wait for him, or shall we attempt the attack elsewhere? We cannot determine this until we have heard from him. This is a map of the town, Captain Gerard. You perceive that within this ring of convents and monasteries are a number of streets which branch off from a central square. If you come so far as this square you will find the cathedral at one corner. In that corner is the street of Toledo. Hubert lives in a small house between a cobbler's and a wine-shop, on the right-hand side as you go from the cathedral. Do you follow me?"

"Clearly."

"You are to reach that house, to see him, and to find out if his plan is still feasible or if we must abandon it."

He produced what appeared to be a roll of dirty brown flannel. "This is the dress of a Franciscan friar," said he. "You will find it the most useful disguise."

I shrank away from it.

"It turns me into a spy," I cried. "Surely I can go in my uniform?"

"Impossible! How could you hope to pa.s.s through the streets of the city?

Remember, also, that the Spaniards take no prisoners, and that your fate will be the same in whatever dress you are taken."

It was true, and I had been long enough in Spain to know that that fate was likely to be something more serious than mere death. All the way from the frontier I had heard grim tales of torture and mutilation. I enveloped myself in the Franciscan gown.

"Now I am ready."

"Are you armed?"

"My sabre."

"They will hear it clank. Take this knife, and leave your sword. Tell Hubert that at four o'clock, before dawn, the storming party will again be ready. There is a sergeant outside who will show you how to get into the city. Good-night, and good luck!"

Before I had left the room, the two generals had their c.o.c.ked hats touching each other over the map. At the door an under-officer of engineers was waiting for me.

I tied the girdle of my gown, and taking off my busby, I drew the cowl over my head. My spurs I removed. Then in silence I followed my guide.

It was necessary to move with caution, for the walls above were lined by the Spanish sentries, who fired down continually at our advance posts.

Slinking along under the very shadow of the great convent, we picked our way slowly and carefully among the piles of ruins until we came to a large chestnut tree. Here the sergeant stopped.

"It is an easy tree to climb," said he. "A scaling ladder would not be simpler. Go up it, and you will find that the top branch will enable you to step upon the roof of that house. After that it is your guardian angel who must be your guide, for I can help you no more."

Girding up the heavy brown gown, I ascended the tree as directed. A half moon was shining brightly, and the line of roof stood out dark and hard against the purple, starry sky. The tree was in the shadow of the house.

Slowly I crept from branch to branch until I was near the top. I had but to climb along a stout limb in order to reach the wall. But suddenly my ears caught the patter of feet, and I cowered against the trunk and tried to blend myself with its shadow. A man was coming toward me on the roof. I saw his dark figure creeping along, his body crouching, his head advanced, the barrel of his gun protruding. His whole bearing was full of caution and suspicion. Once or twice he paused, and then came on again until he had reached the edge of the parapet within a few yards of me. Then he knelt down, levelled his musket, and fired.

I was so astonished at this sudden crash at my very elbow that I nearly fell out of the tree. For an instant I could not be sure that he had not hit me. But when I heard a deep groan from below, and the Spaniard leaned over the parapet and laughed aloud, I understood what had occurred. It was my poor, faithful sergeant, who had waited to see the last of me. The Spaniard had seen him standing under the tree and had shot him. You will think that it was good shooting in the dark, but these people used trabucos, or blunderbusses, which were filled up with all sorts of stones and sc.r.a.ps of metal, so that they would hit you as certainly as I have hit a pheasant on a branch. The Spaniard stood peering down through the darkness, while an occasional groan from below showed that the sergeant was still living. The sentry looked round and everything was still and safe.
