The roof was, like those of most of the houses in the Residency, flat, and intended for the inmates to sit and enjoy the evening breeze. The parapet was very low, but this had been raised by a line of sandbags, and behind them five or six of the defenders were lying, firing through the openings between the bags, in answer to the storm of musketry which the enemy were keeping up on the post. Stooping low to avoid the bullets which were singing overhead, the Warreners moved across the terrace, and lying down, peered out through the holes which had been left for musketry. Gubbins' house stood on one of the highest points of the ground inclosed in the defenses, and from it they could obtain a view of nearly the whole circle of the enemy's batteries. They were indeed higher than the roofs of most of the houses held by the enemy, but one of these, distant only some fifty yards from the Sikh Square, dominated the whole line of the British defenses on that side, and an occasional crack of a rifle from its roof showed that the advantage was duly appreciated. "What do they call that house?" Ned asked one of the officers on the terrace. "That is Johannes' house," he answered. "It was a terrible mistake that we did not destroy it before the siege began; it is an awful thorn in our side. There is a black scoundrel, a negro, in the service of the king of Oude, who has his post there; he is a magnificent shot, and he has killed a great number of ours. It is almost certain death to show a head within the line of his fire." "I wonder we have not made a sortie, and set fire to the place," said Ned. "The scoundrels are so numerous that we could only hope to succeed with considerable loss, and we are so weak already that we can't afford it. So the chief sets his face against sorties, but I expect that we shall be driven to it one of these days. That new battery is terribly troublesome also. There, do you see, it lies just over that brow, so that the shot from our battery cannot touch it, while it can pound away at our house, and indeed at all the houses along this line." "I should have thought," Dick said, "that a rush at night might carry it, and spike the guns." "No; we should be certain to make some sort of noise, however quiet we were. There are six guns, all loaded at nightfall to the muzzle with grape; we know that, for once they fancied they heard us coming, and they fired such a storm of grape that we should have been all swept away; besides which, there are a large number of the fellows sleeping round; and although sometimes the battery ceases firing for some hours, the musketry goes on more or less during the night."
