With a tender farewell of his father and brother, the midshipman prepared for his expedition. One end of the rope had been fastened round the large mast which rose from the dome. Holding the coil over his shoulder, Dick made his way down the dome, on the side opposite that at which they had ascended, until it became too steep to walk; then he lay down on his back, and paying the rope out gradually, let himself slip down. The lower part of the descent was almost perpendicular; and Dick soon stood safely on the terrace. It was, as he expected confidently that it would be, quite deserted on this side. Then he let go of the rope, and Major Warrener, who was watching it, saw that the strain was off it, pulled it up a foot to make sure, and then untied the knot. Dick pulled it gently at first, coiling it up as it came down, until at last it slid rapidly down. He caught it as well as he could, but he had little fear of so slight a noise being heard on the other side of the great dome; then he tied the rope to the parapet, lowered it carefully down, and then, when it was all out, swung himself out over the parapet, and slid down the rope. The height was over eighty feet; but the descent was a mere nothing for Dick, accustomed to lark about in the rigging of a man-o'-war.
He stood perfectly quiet for a minute or two after his feet touched the ground, but outside everything was still. Through the open-carved stonework of a window he could hear voices inside the tomb, and had no doubt that the leaders of the enemy's force were there.
From the parapet, in the afternoon, he had gained an accurate idea of the position of the cavalry, and toward this he at once made his way. He took off his boots and walked lightly until he approached the enemy's bivouac. Then he went cautiously. The ground was covered with sleeping figures, all wrapped like mummies in their clothes; and although the night was dusk, it was easy in the starlight to see the white figures. Even had one been awake, Dick had little fear, as, except near a fire, his figure would have been indistinguishable. There was no difficulty, when he neared the spot, in finding the horses, as the sound of their pawing the ground, eating, and the occasional short neigh of two quarreling, was clearly distinguishable.
Their position once clear, Dick moved round them. He had noticed that four officers' horses were picketed further away, beyond the general mass of the men's, and these could therefore be more easily removed, and would, moreover, be more likely to be fast and sound. They had, too, the advantage of being placed close to the road by which the English force had marched on the day before.
Dick was some time in finding the horses he was on the lookout for; but at last he heard a snorting at a short distance off, and on reaching the spot found the horses he was in search of. They were all saddled, but none had bridles. It would be, Dick knew, useless to look for them, and he felt sure that the halter would be sufficient for well-trained horses.
Before proceeding to work he reconnoitered the ground around. He found the way to the road, which was but twenty yards distant, and discovered also that the syces, or grooms, were asleep close by the horses; a little further off were a party of sleeping troopers. Dick now cut off the heel ropes by which two of the horses were picketed, and then, leading them by the halters, moved quietly toward the road. To get upon this, however, there was a ditch first to be passed, and in crossing it one of the horses stumbled.
"What is that?" exclaimed one of the syces, sitting up. "Halloo!" he continued, leaping up; "two of the horses have got loose."
The others leaped to their feet and ran in the direction whence came the noise which had awakened them, thinking that the horses had drawn their picket pegs.
By this time Dick was in the saddle, and giving a kick with his heels to the horse he was on, and striking the other with the halter which he held in his hand, dashed off into a gallop.
A shout burst from the syces, and several of the troopers, springing to their feet and seizing their arms, ran up to know what was the matter.
