The Atahualpa was the next ship they came to, and to their unbounded satisfaction they found that she was unprotected by a boom. The Peruvians probably thought that a hostile craft would never get so far without being discovered. The Janequeo was therefore run right under her stem, and the torpedo was affixed without any difficulty, a fuse timed for an hour and a half being lighted. This fuse, too, Jim noticed, seemed to be burning away much faster than it ought, but there was no time to watch it, and the torpedo-boat swung off once more on her mission of destruction.
These two craft were, with the exception, perhaps, of the Union, which was a fast ship, the most formidable in the Peruvian fleet, and Jim experienced a thrill of satisfaction at the thought that the Manco Capac and Atahualpa would, at any rate, not trouble the Chilians again. There was another ship lying close at hand, which Douglas judged to be the fast transport Oroya, because of her paddle wheels, and he made up his mind to attend to her before running back to blow up the Union. He selected her paddle-box as the best place to which to attach the torpedo, and as she, too, was unprotected by any boom, he soon had the bomb fixed in position and the fuse lighted.
“Now, men,” he whispered excitedly to his delighted crew, “we will run down and attend to the only other ship of theirs which is of any use—the Union. Hard over with your helm, quartermaster, and we will get down the harbour again.”
The wheel spun round in Pedro’s sinewy grasp, and the Janequeo’s nose was presently pointing down the harbour.
“Full speed ahead,” Douglas whispered down the tube, “we haven’t much time to lose.” And the little engines began to throb more rapidly, while the screw thrashed the water up astern. They soon passed the Atahualpa again, and Jim could plainly make out the jumping sparks which came from the fuse and hissed into the water, but the sight was hidden from any one up above by the overhang of the ship’s counter, and he felt fairly certain that it could not possibly be discovered before the bomb had exploded and done its deadly work. As they slipped past the doomed monitor Douglas’s eye suddenly caught sight of a dark figure with a rifle over its shoulder silhouetted against the luminous haze thrown off by the lights of Callao, and his heart gave a great bound, for the figure had not been there when the torpedo-boat passed up, and she could now hardly hope to avoid detection.
Jim’s fears were only too well founded, for the sentry saw the Janequeo as quickly as Jim saw the sentry, and in a second the fellow roared a hoarse challenge across the water, discharging his rifle at the boat as she swept past, without waiting for any reply. And indeed there was no need for him to expect an answer to his hail, for he knew that no boat ought to be cruising about there if she were a Peruvian; while, if she were a Chilian—
The rifle-shot was the signal for an immediate uproar; it seemed as though every man must have been asleep at his post, for the Atahualpa’s decks suddenly became literally alive with figures, and rifles began to flash about her in scores, while the bullets pattered round and into the torpedo-boat with most unpleasant accuracy of aim.
“There is no time to destroy the Union now,” hissed Douglas between his teeth; “we shall have to be satisfied with what we have already done, and, caramba! we shall be fortunate if we get away with whole skins. Look out, all people with thin skulls; the Manco’s people are training her big guns on us! Full speed ahead, below there,” he roared, there being no more need now for secrecy; “give her all the steam she can carry, or they will have us for certain.”
The screw was already turning at its utmost speed, however, and not another knot could be got out of the flying little steamer; indeed, she was already doing sixteen, or one knot more than they had any right to expect. Just as Jim spoke, a red rocket leaped up into the still night air with a whistling roar, bursting high up in the sky with a shower of brilliant red stars.
“A signal to the patrols in the bay!” cried Jim; and at the same moment the huge 15-inch gun on board the Manco Capac roared out its vengeful message. “We shall have to hurry to get clear now, and no mistake.”
