Before throwing off the warps from the shore the captain gave each man his orders. Two were to stand with fenders, in case the boat drifted either against another craft or against the wall. Two were to take the long poles used for punting. An old sail had been torn up into strips and wrapped round these, with a pad of old rope at the end, so that they could push off from the wall without noise. Not a word was to be spoken in case of their being hailed, nor was there to be the slightest movement on board unless the use of the fenders or poles were required. Lastly, all took off their boots. It was half an hour after the turn of the tide when the warps were thrown off. The tide in the inner port was so sluggish that it was absolutely necessary to pole the boat along until she got out into what was known as the Old Haven, which was the cut leading down from the town to the river. The work was noiselessly done; and Ned, standing at the bow beside the skipper, scarce heard the slightest sound. The night was fortunately very dark, and looking intently he could hardly make out the outline of the shore on either side. In a quarter of an hour they emerged from the inner port. On their left hand the wall of the fortifications connecting the town with the north fort at the mouth of the haven rose high above them, but its outline could be seen against the sky. The captain had told the men poling to take her sharp round the corner, and keep her along as close as possible to the foot of the wall, as she was far less likely to be observed by any sentry who might be there than she would be if kept out in the centre of the cut. Very slowly the boat drifted along her course, assisted occasionally by the men pushing with their poles against the foot of the wall that rose a few feet from them, while those with the fender stood in readiness to place them in position should the ship approach so close to the wall as to render contact probable. The captain was now at the tiller, the way given her by the poles being sufficient to enable him to keep her on her course close to the wall. Another quarter of an hour and they were at the end of the wall, for the forts at the entrance were detached. They were now approaching the most dangerous portion of the passage; they were no longer sheltered in the shadow, but must go along openly. It was, however, improbable that there would be sentries on the face of the fort looking towards the town, and Ned, accustomed as he was to keep watch on deck at night, could scarce make out the low shore a few yards away, and felt pretty confident that the eyes of the sleepy sentries would not be able to pierce the gloom. The men had ceased poling now, only giving an occasional push to keep her head straight and prevent her from swinging round. Presently a sailor standing next to Ned touched his arm and pointed to the right, and straining his eyes he could dimly make out a dark mass looming in that direction.
