"Now, Peter, I had better go first again; when I shake the rope from below, all's right." O'Brien descended, and in a few minutes the rope again shook; I followed him, and found myself received in his arms upon the meeting of the drawbridge; but the drawbridge itself was up. O'Brien led the way across the chains, and I followed him. When we had crossed the moat, we found a barrier-gate locked; this puzzled us. O'Brien pulled out his picklocks to pick it, but without success; here we were fast. "We must undermine the gate, O'Brien; we must pull up the pavement until we can creep under." "Peter, you are a fine fellow; I never thought of that." We worked very hard until the hole was large enough, using the crowbar which was left, and a little wrench which O'Brien had with him. By these means we got under the gate in the course of an hour or more. This gate led to the lower rampart, but we had a covered way to pass through before we arrived at it. We proceeded very cautiously, when we heard a noise: we stopped, and found it was a sentry, who was fast asleep, and snoring. O'Brien thought for a moment. "Peter," said he, "now is the time for you to prove yourself a man. He is fast asleep, but his noise must be stopped. I will stop his mouth, but at the very moment that I do so you must throw open the pan of his musket, and then he cannot fire it." "I will, O'Brien; don't fear me." We crept cautiously up to him, and O'Brien motioning to me to put my thumb upon the pan, I did so, and the moment that O'Brien put his hand upon the soldier's mouth, I threw open the pan. The fellow struggled, and snapped his lock as a signal, but of course without discharging his musket, and in a minute he was not only gagged but bound by O'Brien, with my assistance. Leaving him there, we proceeded to the rampart, and fixing the crow-bar again, O'Brien descended; I followed him, and found him in the river, hanging on to the rope; the umbrella was opened and turned upwards; the preparation made it resist the water, and, as previously explained to me by O'Brien, I had only to hold on at arm's length to two beckets which he had affixed to the point of the umbrella, which was under water. To the same part O'Brien had a tow-line, which taking in his teeth, he towed me down the stream to about a hundred yards clear of the fortress, where we landed. O'Brien was so exhausted, that for a few minutes he remained quite motionless; I also was benumbed with the cold. "Peter," said he "thank God we have succeeded so far; now we must push on as far as we can, for we shall have daylight in two hours."
