Marcelline made no reply, but darted from him, and ran towards the Aurelian Wall.

Plunging into the dry fosse which skirted the wall, she hurried along the bottom of the trench for some distance in the direction of the Vatican. All at once she stopped, and clapped her hands. At the signal, a ladder was let down, and, mounting it, she gained the ramparts.

Marcelline fancied her movements were unobserved, but she was mistaken. Curious to ascertain how she could gain access to the city, Pomperant had followed her. On approaching the spot where she had disappeared, he perceived that the old wall, which was built of brick, and of great solidity, was in this part considerably dilapidated—so much so, as almost to form a breach.

After carefully examining the spot, he hastened back to Bourbon's tent to acquaint him with the important discovery he had made. Bourbon had thrown himself on a couch, but without divesting himself of his armour, and he was wrapped in the last slumber he was destined to enjoy, when Pomperant entered his tent, and aroused him.

“I am sure your highness will forgive me for disturbing you,” he said, “when I tell you that I have discovered a breach in the walls.”

“Ha! that is indeed good news!” cried Bourbon. “But how did you make the discovery?”

“I made it while following Marcelline to see how she entered the city,” replied Pomperant.

“Take me to the spot,” said Bourbon. “I must be satisfied with my own eyes that you have not been deceived. It is strange that you roused me from a dream of the assault. I thought an angel with a flaming brand stood on the battlements to drive me back, but I went on. Listen to me, Pomperant. When dealing with the miserable Milanese, as you know, I took Heaven to witness that I meant them fairly, wishing I might perish by the first shot at the first battle if I played them false. This is the first battle, and not a shot has yet been fired.”

“The first shot will not harm you, my lord,” rejoined Pomperant. “You did not wilfully deceive the Milanese. The Spanish soldiers refused to obey your orders.”

“True,” replied Bourbon; “but I feel that I violated my promise, and if Heaven punishes me, I cannot complain. But come. Let us examine the wall.”
