Thanking the girl with a glance, Bob sprang over the barricade, and, with a parting order to Ah-Sam to remain with the ladies, set off to join his late enemy. At the mouth of the gully he found that the Chunchuses had taken up positions behind every available rock. They were somewhat tightly packed, and as some of them moved from their places to meet their returning leader, and for a moment left cover, the Russians began to take snap shots at them from the crest of a hillock about six or seven hundred yards away. One man was hit just as Bob reached the band. There was a reply from several of the Chunchuses; but it was clear that they were hopelessly outranged. Their muskets did indeed carry the distance of the Russian position, but with no accuracy, and as the Russians were careful to present no considerable target, they were unlikely to suffer any loss. Peering cautiously round the edge of a boulder, Bob looked across the valley in the direction pointed out to him. At first he could see nothing; then, on the crest of the hillock, he saw one or two moving objects which by and by resolved themselves into the caps of men on the other side. He wondered why the Russians, armed as they were with good weapons, did not advance boldly to the attack; but the explanation soon suggested itself. The horses of the Chunchuses having been stampeded, escape for the latter was impossible. The Cossacks recognized that they had them in a trap, but were disinclined to throw away lives by coming to close quarters in broad daylight with a strongly entrenched enemy. At nightfall, however, the odds would be all in their favour. They outnumbered the Chunchuses by at least two to one; under cover of night they could easily rush the position through the wide gaps between the boulders; and in a hand-to-hand fight their superior numbers were bound to tell. Bob had no doubt that they would defer their attack until night, and that was a serious danger to be provided against.
