"He and the others know nothing about it," he said, "and it is just as well that they shouldn't, for he is somewhat rigid in his notions, and might be rather horrified at your assaulting a bishop, however great a scoundrel he might be, and would be specially so at the borrowing of his ring."

At twelve o'clock heavy peals of thunder were heard, followed by a tremendous outbreak of firing from the intrenchments, two hundred guns and a terrific musketry fire opening suddenly.

"The French are attacking!" Herrara exclaimed.

"I don't think so," Terence replied. "It is more likely to be a false alarm. The troops may have thought that the thunder was the roar of French guns. Soult would hardly make an attack at night, or, not knowing the nature of the ground behind the intrenchments, his men would be falling into confusion, and perhaps fire into each other."

As, after a quarter of an hour of prodigious din, the fire slackened and presently ceased altogether, it was evident that this supposition was a correct one. The morning broke bright and still, and an hour later the cannonade began again. Terence at once, after telling Herrara to form the troops up and march them down to the end of the bridge, left the camp, and after proceeding a short distance took off his uniform and donned the attire of the ecclesiastic, and then hurried down into the town. He was accompanied by the two troopers in their peasant dress. These left him at the bridge. The din was now tremendous, every church bell was ringing furiously, and frightened women were already crowding down towards the bridge.

Their point of crossing had already been decided upon--it was at the end of a street close to the convent, and when Terence reached the convent the two men were already standing at the end of the street, awaiting him.

"Now, you do your part of the business and I will do mine," Terence said, and he moved forward to the door of the convent, where he would be unseen should anyone look out.

The two troopers went to the middle of the street, opposite the window which the officer had described to Terence, and both shouted in a stentorian voice:

"Mary O'Connor!"

The shout was heard above the tumult of the battle and the din in the city, and a head appeared at the window and looked down with a bewildered expression.
