Bob privately wished that he felt anything like the same assurance. Two days passed, during which his anxiety did but deepen. No movement was made by the Russians. This fact only increased his uneasiness, for it was a proof that the worst of the position had yet to be faced. One of the mules had been killed and cut up; Bob found, indeed, that the Chunchuses were almost reckless in their consumption of the flesh, and he had to impress upon Sing-Cheng the necessity of putting them on fixed rations. At best the fare was meagre; the animals were hardy and muscular, but with no superfluous flesh; and what flesh there was was not too wholesome without vegetable food. The men ate their scanty rations without grumbling, but they objected to the feeding of Chang-Wo; in him, indeed, Sing-Cheng had recognized an enemy against whom he bore an old-standing private grudge. He was for killing the Manchu out of hand; he reeled off to Ah-Sam a long and passionate account of the evils he had done. But Bob insisted that the prisoner must be fed exactly as themselves, and kept him bound hand and foot to the cart.

On the third day, shortly after dawn, Bob was disconcerted to find that the enemy had achieved what Sing-Cheng had declared to be impossible. Shots from a point high up the cliff on his left told him that in some way, probably by making a considerable detour, the Russians had gained a position whence they could enfilade his encampment behind the boulder. The new danger to which he was exposed was soon brought home to him. The enemy, themselves for the most part under cover, began to pick off the Chunchuses, while their comrades on the hill in front kept up a hot fire which showed that escape in that direction was impossible. The unfortunate garrison were placed in a desperate plight. If they shifted their ground to avoid the flank attack they exposed themselves to the enemy on the hill. To neither could they make any effective reply. In the first place their arms were ineffective at the range, and secondly, the Russians had all the advantage of cover. Bob himself, with his more accurate rifle, managed to put hors de combat one or two of the enemy who exposed themselves; though he dared not shoot as often as opportunity offered, for his stock of ammunition was small, and it was necessary to husband it.

As his men dropped one by one he recognized at length that the position was untenable. He must withdraw them behind the barricade above, which was protected by the contour of the hill from the marksmen on the cliff. But this raised the question, what was he to do with the ladies? There were two reasons against their remaining where they were. First, seventy Chunchuses huddled in the small free space behind the barricade were scarcely fit company for them; secondly, they themselves would be in the way if the Russians pushed home an attack. Both Mrs. Pottle and Ethel had up to the present borne the stress of the situation with good heart, and under Ah-Sam's tuition had become adepts in the cooking of rice and millet, which, with tea, brewed in diminishing strength daily, was their only sustenance. Bob did his best to disguise from them the full gravity of the position, but felt all the time that they must see the hollowness of his assurances.

While he was wondering what to do for the best, his eye lit on the fissure in the rock above which had attracted his attention when he first came along the road. Was it deep enough, he wondered, to afford protection to the two ladies? At the mouth it was exposed to the enfilading fire of the Russians, but if it extended for any considerable distance into the rock, it might form a place of refuge. He resolved to explore it. It could only be approached by the shelf of rock that abutted on the mountain stream, and this for the greater part of its length was sheltered from the enemy. But there was a strip of some twenty yards lying in the interval between two shelving rocks, and this was quite open. It would be a case of running the gauntlet. He looked round in final search of another way; there was none; he must himself take the risk.

But it was necessary first to ensure the safety of his little force during his absence. He therefore withdrew the greater part from the wall at the mouth of the gorge, leaving only a dozen men, who were protected from the fire of the Russians on the heights by a projecting spur of the hill. These being the best marksmen could probably hold the enemy in check for a time, but Bob ordered them to withdraw behind the upper barricade if the Russians, realizing the weakness of the defending force, should at last attempt a rush. Meanwhile the men he had withdrawn were set to construct with boulders a small fort high up the gorge just under the waterfall; this would form excellent vantage ground in case the Russians occupied the lower portion of the gully.

These arrangements having been made, Bob left the ladies in charge of Ah-Sam and started on his hazardous expedition. Knowing that the fissure, if of any considerable depth, must be quite dark, he took with him a torch improvised out of a piece of sacking smeared with mule fat, and a box of matches. He climbed over the intervening rocks, turned a corner, reached the ledge, and walked along until he came to the exposed portion, where he halted for a moment. Then, springing forward like a sprinter, he dashed over the narrow shelf at the imminent risk of stumbling and falling to the rocky bed of the stream fifty feet below. He was seen by the Russians on the hill, and in the few seconds he took to complete the passage he heard a patter of bullets on the rocks, and one or two even followed him as he gained the opening and plunged in. But he had escaped unhurt, and safe in the fissure he paused to take breath and to light his torch, reflecting that he would run double danger in coming out, for the Russians would doubtless be on the watch for him.

Making his way into the cleft, he found that it was broader than he had expected. After about twenty yards it took a sudden curve to the left, and then widened into a jagged irregular passage some four yards in breadth, and of varying height. At one moment, torch in hand, he had to stoop to avoid a sharp edge of rock; a little later the passage was at least twenty feet high. He had penetrated as nearly as he could judge for about fifty yards, when his steps were arrested by the faint sounds of firing behind him, and he hurried back. As he approached the opening the sound became so loud and continuous that he felt sure a stiff fight was in progress. Keeping close to the less-exposed wall of the cleft at its mouth, he saw from his elevated position that the Russians were at last making the long-expected attack. From the hill a hot fire was being brought to bear upon the mouth of the gully, while a number of the enemy were just emerging from round the hillside to the right, being protected from the fire of the dozen Chunchuses by the boulders. They were making for the right extremity of the barrier, a point which it was impossible to defend because of the direct and rapid firing from the hill.

Clearly the twelve men gallantly holding their own at the mouth of the gully were in danger of being cut off. Bob only took a second or two to recognize the urgency of the case; then, springing on to the ledge at the mouth of the cleft, he rushed along it at breakneck speed, and owed his safety to his quick movements, for before the Russians caught sight of him, occupied as they were with keeping down the fire from the barrier beneath, he had covered several yards, and the snap shots they then took flew wide of the mark. Arriving at the corner, he shouted to Ah-Sam below an order to recall the men from the breastwork. The command was instantly given, and the brigands, running like cats from rock to rock, scrambled up the gully and flung themselves pell-mell through a small gap left for them in the barricade above, one or two of them being hit by Russian bullets. The advancing enemy at once occupied the far side of the abandoned breastwork, and opened fire on the upper defences; but when a few attempted to cross and move up the gully the fire of the Chunchuses proved too hot for them, and they hastily retreated.

Except that the defenders were now driven into a more confined space, the general situation had from the Russian point of view improved but little. The Russians dared not press forward up the gorge, for it had been so thoroughly cleared of boulders for the construction of the barricades that it was almost wholly devoid of cover for an attacking force. The double entrenchments above were even stronger than the breastwork below, and could only be carried at a terrible cost.

By this time Bob had clambered down among his men. Unpleasant news was in waiting for him. Through Ah-Sam the brigand leader informed him that the men's ammunition was running short; they had only an average of five rounds a man remaining. This was an irremediable misfortune. Only one course was possible. All the available ammunition was collected and distributed, principally among the twenty best shots in the band. Ten of these men were stationed at the barricade by the carts, and ten in the fort recently constructed higher up the gully. The remainder of the garrison were given one round apiece, and this was only to be used on an emergency. They were to make no attempt to reply to the fire of the Russians. Bob stationed himself by the cart where Chang-Wo was still bound, and fired a shot at intervals whenever an incautious member of the attacking force presumed on the general silence of the besieged and emerged from cover. More than once his shots took effect, and as a result the enemy became more cautious, keeping well behind the shelter of the rocks, and settling themselves to establish a strict blockade.
