Jim found, upon rejoining the Blanco Encalada, that there was great excitement prevailing aboard that ship; for the fleet had received orders to sail, that very day, for the port of Arica, and the squadron was only waiting for Commodore Riveros, who had superseded Rebolledo Williams, to come aboard to start.
There were numerous rumours flying about the Blanco as to the object of the cruise northward; but the one which obtained most credence was to the effect that the Chilian fleet had been instructed to find and destroy the Huascar, Union, and Pilcomayo, which were waging a destructive war against the Chilian commerce, and which, it was very strongly suspected, had been guilty of certain acts against Chilian and other craft which more nearly resembled piracy than civilised warfare. So much damage, indeed, had been wrought by them that the Chilian Government had decided to hunt down the obnoxious craft; and for this purpose there were now assembled in Valparaiso harbour the Almirante Cochrane and Blanco Encalada, both battleships, the corvette O’Higgins, and the armed merchant-steamers Loa and Mathias Cousino. The little gunboat Covadonga had also been intended to sail with the squadron, but, as has been seen, she had been too badly damaged in her gallant fight with the Peruvian vessels to permit of her doing so.
Mid-day came, but it brought no sign of the commodore; and it was three o’clock in the afternoon before his launch was seen to steam away from the naval steps at the jetty. The side was then piped, and Riveros came on board, to the accompaniment of the flagship’s band and a crashing salute from the other vessels in the harbour. Upon his arrival on board he immediately went below to his cabin and sent for his captain, with whom he was in close conference for about an hour. Apparently he informed him as to the plan of campaign, for soon after Captain Castello came on deck it became known, all over the ship, that a telegram had been received from a Chilian spy in Arica to the effect that the Huascar and the Union were to call in at that port in about three days’ time, and that they would be detained there for about a week in order to effect certain repairs. Therefore, should the Chilians sail immediately, suggested the telegram, they would be almost certain to catch their prey without difficulty. It was also within the bounds of possibility that the Pilcomayo and Manco Capac might likewise be there; and in that case, since the opposing forces would be pretty evenly matched, there was every prospect of a general engagement being fought, a prospect which aroused the keenest enthusiasm of every man in the fleet, and more especially that of such young hot-bloods as Jim and his friend O’Meara, to say nothing of Lieutenant Montt, who was being transferred, to his great gratification, from the Covadonga to the Blanco Encalada.
A few minutes after Captain Castello had come on deck the bugles shrilled out, “Clear lower deck. Hands up anchor!” and the seamen came tumbling up from below, happy and eager as a parcel of schoolboys off for a holiday. A string of signal-flags soared aloft to the Blanco’s mainyard-arm, and half an hour later her screw began to revolve as she led the way out of the harbour, with the other ships following, in column of line ahead.
It was five o’clock in the afternoon of October 1, 1879, and the cruise had begun which was to prove so eventful for at least two of the ships comprising the squadron. As they passed out to sea with ever-increasing speed the forts on either side of the bay fired a farewell salute; and the spectacle of the sun sinking over Monte Bajo and the Centinela Alto, coupled with the lurid flashes of flame and clouds of white smoke from Forts San Antonio, Bueras, Valdivia, and the Citadel, constituted a picture the grandeur of which Jim never forgot.
A very careful look-out was maintained during the progress of the fleet up the coast, and Commodore Riveros took the precaution to look into Chañeral Bay, Cobija, and Iquique, to make quite sure that the Peruvians—who might possibly have got wind of the expedition—should have no chance of escaping by lying hidden until the Chilians were past, and then making a sudden dash southward upon the comparatively defenceless ports of the lower coast.
There was, however, no sign of the enemy anywhere in any of these places, and all the news that Riveros was able to pick up tended to confirm the telegram which he had received at Valparaiso, to the effect that the Peruvians would certainly be found at Arica. Having, therefore, made certain that they had left no enemy in their rear, the Chilians steamed away from Iquique on the 3rd of October, and arrived at a point ten miles to the south of Arica at three o’clock the next morning, where the fleet hove to, in order to allow of a council of war being held by the commodore and captains in the cabin of the Blanco Encalada.
The captains of the Cochrane and the O’Higgins were in favour of an attack by the whole squadron upon the Peruvian fleet supposed to be lying in the harbour, but the commodore, with the captains of the Loa and Mathias Cousino, opposed that plan, on the grounds that the harbour was very strongly defended by forts; consequently, if such an attack were carried out the Chilians would be obliged to silence the batteries before they could turn their attention to the Peruvian ironclads. The scheme favoured by Riveros, and which was ultimately carried out, was to send in a number of steam-launches from the ships, each armed with a couple of spar-torpedoes, and try to blow up the Peruvian ships. The commodore’s argument was that they would almost certainly be successful, if the attack were properly made; while, if it were to fail, the Peruvians would be certain to come out of port in pursuit of the torpedo-boats, and find themselves face to face with the Chilian fleet, and beyond the protection of the shore batteries.
This having been decided upon, the captains returned to their ships, and the squadron once more headed northward, at a speed of about five knots, finally coming to an anchor some four miles away from Arica, but completely hidden from it by the headland of Santa Catharina, which forms the southern extremity of the bay. The steam-launches of the Almirante Cochrane and the Blanco Encalada were then lowered into the water, together with a small Hereschoff torpedo-boat which the O’Higgins had brought up on her deck. These little craft all rendezvoused at the flagship, and spar-torpedoes were hastily fitted to all three, one projecting from the bow of each boat. As the expedition was likely to be an extremely hazardous one, Commodore Riveros decided to call for volunteers to man the torpedo-boats; and Jim Douglas and Jorge Montt were the first two officers who presented themselves for the service, while Terry O’Meara asked to be allowed to accompany his chum, should the latter be accepted, to take charge of the engines of the boat in which Jim was to go.
