Jack had moved some little distance in advance of his troop. What he had seen sent him in haste to rejoin Wang Shih.
"We must get our men under cover," he said. "There are Cossacks, I believe, descending the opposite hills. They may not have seen us yet."
The Chunchuses moved within cover of the nearest trees, and Wang Shih sent forward his keenest scout on foot to ascertain whether the new-comers were enemies or friends. He returned in a few minutes declaring that even at this distance he had distinguished the characteristic head-dress of the Cossacks. Wang Shih was disposed to remain in cover until the time came for him to carry out Ah Lum's orders. In his present position he ran little risk of being seen by the oncoming party, and being entirely without imagination it did not occur to him that the situation was now perhaps radically altered. But to Jack the discovery seemed to be serious. The line of advance taken by the second body of Cossacks would bring them within an hour across Ah Lum's rear. The position had been strangely reversed. While Ah Lum believed that Wang Shih was cutting off the retreat of the first body, his own rear was in process of being threatened by a force twice as numerous as the one he could dispose of. He was probably in ignorance of the danger, for the advancing Cossacks were shut from his view by the contours of the hills, and there was little likelihood now of a warning being conveyed to him by a Chinese villager. It was impossible for a messenger to reach him from Wang Shih, for the first Russian force lay between.
Jack pointed out to Wang Shih the peril in which his chief lay. The Chunchuse admitted it, but asked what he could do. With his assistance Ah Lum might beat the first body of the enemy before the second could arrive, and then could turn his attention to it in its turn.
"But suppose the fight takes a long time? And suppose we do not succeed in beating the first Russian force? If they hold us until the second arrives, Mr. Ah's men will be attacked from the rear, and they will certainly be crushed between the two."
"It is as you say. But the chief has given me orders; he will be angry if I disobey. It is better to carry out orders."
It was evident that Wang Shih was disinclined to assume any responsibility. Jack was by no means satisfied that things must be allowed to take their course. It appeared to him of the utmost importance that the second Russian force should be held in check until the first had been disposed of. He went through the clump of bare trees until he reached the summit of the crest, and looked anxiously towards the advancing band.
About a mile away the hill path it was following disappeared in a cleft in the hills, reappearing a quarter of a mile farther on. It seemed to Jack that at this spot, resembling somewhat the position Ah Lum had taken up, it was possible to hold the Russians in check. So far as he could see, there was no better place along their route for such an attempt, and he instantly made up his mind that the attempt must be made. It was doubtful whether the Chunchuses could reach the cleft in time to occupy it before the Cossacks arrived, but there was a bare chance, and he resolved to take it.
Hastening back to Wang Shih he explained that he proposed with his own division of men to make for the cleft, leaving the rest to carry out Ah Lum's instructions. Wang Shih raised no objection; he merely stipulated that Jack should accept the full responsibility for his action. In a few minutes, therefore, Jack rode off at the head of his band; almost immediately after starting he heard the dull sound of firing in Ah Lum's direction; the fight in the pass had begun. Clearly there was no time to lose, for the same sound would certainly quicken the approach of the second body of Russians.
Keeping down the hill in order to screen his movements as long as possible from the enemy, Jack led the way at as rapid a trot as the rugged ground allowed. Only a few minutes had passed when the little force rode out on to the open hillside, where they must be seen by the Russians. Jack fancied that the enemy was at this time nearer to the cleft than his own men; but the Chunchuses were riding downhill, the Russians up, which gave room for hope that he might reach the position first. He was helped also by the more open character of the ground on his side, and by the fact that for some time the Russians failed to recognize the object of the horsemen riding at full speed towards them. During these precious moments Jack's party gained several hundred yards. Keeping one eye on the rough ground and the other on the enemy, Jack noticed that the leading files broke from a walk into a trot and then into a headlong scramble. It was now neck or nothing. Throwing caution to the winds, he dug his spurs into his pony, and clattered at breakneck speed down the slope, the Chunchuses hard at his heels. Several ponies stumbled and came to their knees, flinging their riders; but the rest, intoxicated with the excitement of the race, rode unheeding after their leader. A dip in the ground now hid the two forces from one another; they would not again come in sight until the cleft was reached. Between the Chunchuses and the point they aimed at lay a comparatively clear space, dotted by a few single boulders without any of the smaller stones that for most of their ride had impeded their progress. Now Jack urged his panting steed to a mad gallop; the quarter-mile was covered in a few seconds; he dashed into the cleft, the foremost of his men but a length behind.
