So far, then, all was right; but he felt that at any moment he might hear others coming along behind, and those might strike the very spot where they two were lying.
Thought after thought of this kind flashed through Bracy’s brain, as he tightened his hold of the bayonet, and held it point upward ready for use against his first assailant, while the strange crepitation of the frozen snow went on for what seemed like a long period, so greatly was everything magnified by the excitement through which it was mentally viewed.
By degrees, though, the creeping sound, which had seemed to stop more than once, ceased entirely, and the listeners waited quite half-an-hour, fancying twice over that they heard the faint click of stone against stone; but they could not be sure, and they dared not communicate otherwise than by a pressure of the hand, for there was still the possibility of the enemy being close in front. Though as the minutes crawled slowly by, and no fresh sound was heard, the feeling grew stronger and stronger that they had attributed the creeping noise to the enemy, when it was probably some inoffensive wild creature seeking for food, while the enemy had passed the spot in the dark, and were by now far away.
Bracy had just come to this conclusion, and had begun to think of the wisdom of crawling off the snow, which was beginning to melt beneath him from the warmth of his body, when his heart gave a leap as if some nerve had received a sudden twitch. For there came low and clear from a short distance away a peculiar sound such as might be produced by a night-bird on the wing. Then all was still once more.
“Was that a signal?” thought Bracy; “or have we been deceived?”
He thought earnestly, and felt that, after all, the enemy would under the circumstances act just as they were acting. There seemed to be an excess of caution, but none too much, approaching as they would be to surprise whoever was on the watch, and going with their lives literally in their hands.
“Phit!”
The same low, peculiar sound again, making Bracy start into a wild fit of excitement. Then there was a quick running as of many feet towards the central spot, followed by clink, clink, clink—the striking of steel on stone, and then a momentary silence, followed by a peculiar rumbling and a burst of voices.
“Gug!”
Bracy turned sharply, bayonet in hand, ready to strike, for the horrible thought struck him that Gedge had just received a tierce thrust which pinned him to the frozen snow; but as he leaned in his direction a hand touched his wrist and gave it a grip, holding it tightly, and making him draw a deep breath full of relief.
