"I hope not, Hugh; but we must take our chance. I would rather that than be drowned gradually. But look, the water is up nearly to our waists now; and the boat must be pretty nearly sinking. I will take hold of the cord. Then both of us throw ourselves down to the floor, and I will pull the string. Three feet of water over us ought to save us; but mind, the instant you feel the shock, jump up and rush for the opening, for it is pretty sure to sink her.
"Now!"
The lads dived under water, and the instant afterwards there was a tremendous explosion. The deck of the boat was blown into the air in a hundred fragments, and at the same moment the boat sank under the water.
A few seconds later Rupert and Hugh were swimming side by side. For a while neither spoke--they were shaken and half stunned by the shock.
"It is a thick fog, Hugh. All the better; for if those scoundrels come back, as is likely enough, there is no chance of their finding us, for I can hardly see you, though I am touching you. Now we must paddle about, and try to get hold of a spar or a bit of plank."
[Chapter 12]: The Sad Side Of War.
Before firing the keg of powder, Rupert and Hugh had rid themselves of their jackboots, coats, and vests, and they therefore swam easily and confidently.
"Listen, Hugh! Here is the boat coming back again," Rupert exclaimed. "This thick mist is fortunate, for they can't see twenty yards. We can always dive when they come near. Mind you go down without making a splash. We are all right at present; the boat is going to our right, let us swim quietly in the other direction."
Presently they heard a voice in English say, "It is no use our troubling ourselves. It's a mere waste of time. The young rascals are dead. Drowned or blown up, what matters it? They will never trouble you again."
"You don't know the villains as well as I do. They have as many lives as cats. I could have sworn that they were burned at that mill, for I watched till it fell, and not a soul came out; and to this moment I don't know how they escaped, unless they flew away in the smoke. Then I thought at any rate the chief rogue was done for, when Muller wrote to tell me he was going to finish him for me the next day. Then they both got through that day's fighting by the Scheldt, though I hear they were in the front of it. And now, when I leave them fastened up like puppies in a basket, in a sinking boat, comes this explosion, and all is uncertain again."
