"For God's sake, sentry, give me some water! I'm choking—oh—oh water! water!"
He waited to see if the sentry would heed the call. He knew that the men inside could not betray him, for, if they were not asleep, they could not be sure that the voice was not from among themselves. Sure enough, the sentry's step ceased. Was he near the door? Jack crept to the corner. Yes, he had halted at the aperture. Would he enter? Jack stepped back to his post, as the guard called out:
"Where are you? Which of you wants water? Sing out!"
"Here!" Jack cried, "Here!" Then darting back to the corner, he was just in time to see the man lean his gun against the door-post, and disappear in the hut. In an instant the gun was in Jack's possession, and he was behind the Samaritan in quest of the suffering victim. It was dark as a tunnel. Jack's victim still gave him the aid he needed, for, as he groped along the wall, he said, good-humoredly:
"Sing out again, my friend; I haven't got cat's eyes."
Jack's grasp was on his throat and Jack's mouth was at his ear.
"One sound, one word, and this knife goes to the hilt in your heart!"
The astounded man half reeled at this awful apparition in the black darkness, and he limply yielded to his captor under the impression that the prisoners were loose and upon him. Jack tied the man's unresisting hands with his own canteen-straps; then seated him near the wall and lighted a match. Four men, undisturbed by this swift and noiseless coup, were stretched on the board floor, breathing the heavy, deep sleep of exhaustion. Jack aroused them with the greatest difficulty, and found it still harder to make them understand that, with courage and resolution, they would be back in their own lines by daylight. When this became clear to them they were as eager and energetic as their rescuer. The men were to remain near the blockhouse, but not in it, until Jack returned for the negro, and then under the lad's guidance they could find their way to the Union outposts. Just as this was decided, a blood-curdling baying of bloodhounds echoed across the pond from the distant cabin. Jack trembled, his mind at once on Dick, so near and yet so far from him now, in this new danger. There was not a moment to be lost. Perhaps even now all the night's hard-won victories were to be turned to worse than defeat—prison, death; for the liberation of slaves was at that time punishable by hanging in the rebel military code.
"Courage," he said to himself, grimly; "courage, a dog's no worse than a man. We've overcome them to-night, we ought to be able to tackle the dogs." This new danger changed his plan slightly. Instead of leaving all the men, he took one of the rescued four, Tom Denby by name, with him, and set out for the water. But here another check met him. He suddenly recalled that the guard at the blockhouse had been scattered along the shore to watch the debouch from the swamp. This enforced a wide détour, bringing him out in the rear of the boat and nearer the point where Moccasin Creek emptied into the pond. They reached it finally, and skirting along the shore kept a keen eye on the water for the boat. They had skurried along half-way back toward the bluff, listening for a sound on the water and peering into the black surface, when Denby suddenly touched Jack's arm.
"There's a horse or cow standing in the water yonder. I've seen it move; there, look!"
