"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."

The Warreners lay wistfully watching the battery, whose shots frequently struck the house, and two or three times knocked down a portion of the sandbag parapet—the damage being at once repaired with bags lying in readiness, but always under a storm of musketry, which opened in the hopes of hitting the men engaged upon the work; these were, however, accustomed to it, and built up the sandbags without showing a limb to the enemy's shot.

"There were two children killed by that last shot," an officer said, coming up from below and joining them; "it made its way through the earth and broke in through a blocked-up window."

"We must silence that battery, Ned, whatever comes of it," Dick said in his brother's ear.

"I agree with you, Dick; but how is it to be done? have you got an idea?"

"Well, my idea is this," the midshipman said. "I think you and I might choose a dark night, as it will be to-night. Take the bearings of the battery exactly; then when they stop firing, and we think the gunners are asleep, crawl out and make for the guns. When we get there we can make our way among them, keeping on the ground so that the sentry cannot see us against the sky; and then with a sponge full of water we can give a squeeze on each of the touchholes, so there would be no chance of their going off till the charges were drawn. Then we could make our way back and tell Gubbins the guns are disabled, and he can take out a party, carry them with a rush, and spike them permanently."

"Capital, Dick; I'm with you, old boy."

"Now let us take the exact bearings of the place. There was a lane, you see, before the houses were pulled down, running along from beyond that corner nearly to the guns. When we get out we must steer for that, because it is comparatively clear from rubbish, and we ain't so likely to knock a stone over and make a row. We must choose some time when they are pounding away somewhere else, and then we shan't be heard even if we do make a little noise. We will ask Mrs. Hargreaves for a couple of pieces of sponge; we need not tell her what we want them for."
