Into one of these tents Dick crawled, Ned watching outside. When Dick first entered it was so dark that he could see nothing; but the moonlight penetrated dimly through the double cotton, and he was soon able to discover objects around. The ground was all occupied by sleeping figures, each wrapped up from head to foot in his blanket, looking like so many mummies. Their uniforms were folded, and placed between their heads and the wall of the tent. Six of these, with the same number of caps, and six ammunition pouches and belts, and a uniform cloak, taken carefully off one of the sleepers, Dick collected and passed out through the door of the tent to Ned. Not a sleeper stirred while he did so, and he crept quietly out, with the first part of his task accomplished. Gathering the things together, the boys made all speed back to a clump of trees half a mile in the rear of the camp. Here Ned put on one of the uniforms and the cloak, and they then started back again for the camp. The sentries upon the prisoners' tent were changed at twelve o'clock, and a few minutes later the sentry at the rear of the tent saw one of his comrades come out of one of the large tents close to the end of his beat. He was wrapped in his blanket, and his face was tied up with a cloth. Coughing violently, he squatted himself in front of his tent, and rocked himself to and fro, with his hands to his face, uttering occasional groans. This was all so natural--for the natives of India suffer much from neuralgia in the cold weather--that the sentry thought nothing of the matter. He continued to pace his beat, turning back each time when within a yard or two of the sufferer. The third time he did so the figure dropped off his blanket, and, with a sudden bound, threw himself on the sentry's back; at the same moment a Sepoy in uniform darted out from the tent. One hand of the assailant--in which was a damp cloth--was pressed tightly over the mouth and nostrils of the sentry; the other grasped the lock of his musket, so that it could not be discharged. Thrown backward off his balance, taken utterly by surprise, the sentry was unable even to struggle, and in an instant the second antagonist plunged a bayonet twice into his body, and he fell a lifeless mass on the ground. It was the work of an instant to drag the body a yard or two into the shadow of the tent, and before the other sentry appeared from the opposite side of the prisoner's tent the native was rocking himself as before; the sentry, wrapped in his cloak, was marching calmly on his beat. The whole affair had lasted but twenty seconds, and had passed as noiselessly as a dream.
