At length the commodore decided to send Jim in charge of the Blanco’s torpedo-boat, with Terry O’Meara in charge of the engines. Montt was to take command of the Cochrane’s launch; and a man named Juarez was given the command of the Hereschoff torpedo-boat, which was a craft of about sixteen tons displacement. Jim, as being second lieutenant of the flagship, was given the command of the little squadron; and, after half an hour’s interview with the commodore, during which he received the most minute instructions as to how he was to proceed, he went over the Blanco Encalada’s side into her steam-launch, and gave the signal to start.
There was no cheering at their departure, for all those who were left behind felt that they might never see their comrades again; moreover, it was necessary to maintain the strictest silence, since, the night being very still, sounds would carry to an immense distance over the water. If suspicion were once aroused on shore, it would mean the absolute annihilation of the brave fellows who had started on their desperate errand. The fleet, of course, showed no lights, and neither did the three torpedo—boats; consequently, within a minute after the latter had started the darkness swallowed them up completely, and there was no telling whereabout they were, or what progress they were making.
Jim had, however, most carefully taken his bearings before leaving the flagship, and, by the help of the chart and compass, knew exactly where to find the fleet again when his perilous mission had been accomplished. He steamed along northward over the three or four miles which separated him from Arica in extended column of line abreast, so that the chances of detection should be as much reduced as possible, and so that they could pick up any small craft which might perchance be cruising about in the neighbourhood; and he had already arranged a simple code of signals, whereby the three small steamers might communicate with one another without attracting undue attention to themselves.
Half an hour after pushing off from the Blanco Encalada, the flotilla came abreast of the southern extremity of Santa Catharina island, and Jim knew that in another five minutes he would obtain a full view of the harbour, when he would also know whether his intended prey lay in the roads or not. The heart of every man in the little flotilla beat fast, and his breath came thickly under the stress of the intense excitement of the moment; and Jim, from his position in the stern of the Blanco’s launch, tried to pierce the darkness with his eyes to get the first glimpse of the Peruvian vessels.
A moment later the three boats, closer together now, swept round the northern end of the island, and Arica roadstead lay in full view before them.
It was now the hour before the dawn, and consequently the night was at its darkest, but Jim could hardly repress a cry of delight as he caught sight of four indistinct, dark masses, looming up on the surface of the bay. There were no lights showing anywhere, save in one or two isolated houses on shore, where sickness probably kept the inmates awake; but he had not expected to find any lights showing among the Peruvian fleet, since they would naturally desire to keep their whereabouts hidden from chance Chilian prowlers. But in Jim’s mind there was no doubt that the four shapeless blurs lying close together, about half a mile away, were the vessels of which he had come in search; and he passed the word to the other launches to select each her own particular vessel, torpedo her, and then steam away back to the Chilian fleet. He himself intended to be responsible for two of the Peruvians, while his consorts were instructed to take one a-piece. No conditions, he thought to himself, could have been more favourable to the enterprise. So far as he could make out, no suspicion had been aroused that the Chilians were in the vicinity; the night was dark, and the town seemed to be asleep. In fact, their enemies appeared to be indulging in a feeling of security from which they would awake—too late!
The order was now passed for the launches to ease down to half-speed, so that the sound of the churning propellers might be less perceptible, and the three boats crept forward almost in complete silence upon their prey. Jim could now plainly make out the brig-rig of the monitor Huascar, and the three masts and single funnel of the corvette Union, and these two ships he intended to account for with his own torpedo-boat. Away to the right, close under the forts, and about four hundred yards from the Huascar, lay what looked like a couple of other monitors. He had quite expected, or at least hoped, to find one other monitor there, the Manco Capac, but not a third; for, according to the information received, the fourth ship should have been the Pilcomayo gunboat. But, no matter; it would be as easy to blow up an ironclad monitor as a gunboat; and Jim ordered each of the other two torpedo-boats to select one of the monitors lying under the forts, while he himself steamed toward the vessels which he took to be the Huascar and the Union.
After waiting about five minutes, to allow of the other two launches getting close to their objectives, Jim inquired in a low tone if all was in readiness; and upon being informed that everything was prepared, called in a whisper to Terry O’Meara, “Full speed ahead, and give her every ounce of steam she can carry!”
In response to this command the little steamer’s propeller suddenly started to revolve at a tremendous rate under the pressure of steam which Terry let into the cylinders; her stern dipped several inches deeper into the water, and with a rippling noise like that of tearing silk at her bows, she darted toward the nearest ship, which Douglas took to be the Huascar, and which could not have been more than five hundred yards away.
Nearer and nearer they rushed, the men in the bows craning their necks eagerly forward to see where the torpedo would strike, and Jim, in the stern, crouching over the tiller and holding his boat’s bows fair and square for the middle of his prey. It occurred to him, for a moment, as being rather curious that even now he could detect no signs of life aboard either of the Peruvian ships, for he had fully calculated on the launches being seen and an alarm raised ere he had approached so close. But no suspicion entered his mind, and he thanked his lucky stars that he had been fortunate enough to catch the enemy totally unprepared. It would make his task so much the easier.
