Bob at once went off to make the necessary arrangements. He first sent a number of the Chunchuses down the hillside to a clump of trees on the right, some distance below the wall, to cover the water-carriers and take the Manchus in flank in the event of a sudden assault. Then, under guidance of one of the monks, he himself with twenty men stole out to the left. He stationed the men at equal distances apart down the slope, then started six buckets along the line. As these were filled they were passed up from hand to hand, and returned in the same way when empty to be filled again. Within the walls the monks received the full buckets as they arrived, and emptied them into a large tank behind the temple. The work was done as quickly and quietly as possible, but every now and then one of the men as he moved up the slope to the man above him struck the edge of his bucket against a rock, causing a sound that could hardly escape attentive ears. Such accidents could not be avoided, but at last they occurred so frequently as the men grew tired that Bob thought it time to make good a retreat. Just as he was giving the order, there was an outburst of yells from lower down the slope, and some hundreds of Manchus on foot came surging upwards. Seizing the muskets that lay ready to their hands Bob’s men made a break for the wall, the enemy only a few yards behind them. From the Chunchuses in the clump of trees there was a sharp discharge of musketry, but it was ineffectual to check the rush, which had evidently been prepared with some skill, or the movement could scarcely have been unobserved by Bob’s scouts. It was now nearly dark, and as the men of Bob’s party scrambled in hot haste over the wall they were in imminent danger of being shot down by the excited garrison in mistake for Manchus. Bob was glad that he had been able to leave in command so cool and experienced a warrior as Kobo. As he vaulted over the low wall, pursued by a Manchu, he heard Kobo’s clear voice, incisive amid the tumult, addressing the Chunchuses in their own tongue. Not a man of them fired his piece: it was clear that Kobo had ordered them to await his command. At last, just as Bob, unrecognized in the darkness, had followed the last of his men across the wall, he heard Kobo give a sharp order. There was a rush of Chunchuses to the wall; they had stood some paces back in order to allow their comrades room to get across. Muskets and rifles flashed all along the line; and the cries of wounded men mingled with shouts of rage and defiance as the whole mass of the enemy swarmed up to the low breastwork.
