Like a flash Terry disappeared to rouse the crew, while Douglas continued to watch the approach of the launch, in a perfect agony of apprehension. The little craft was very close indeed now, and, steaming at the rate of some nine knots, she would be alongside the Blanco Encalada in a couple of minutes; and once alongside the battleship, nothing could save the latter from destruction.
But anxiety lent wings to Terry’s feet, and in a few seconds the men made their appearance on deck, in all stages of undress, for they fully appreciated the dangers of the situation and had not waited to clothe themselves. Their officers also had dashed up from below, and hurried words of command flew from one quarter of the ship to another. Admiral Williams himself rushed up from below, upon the alarm being given, and he now instructed the ship’s bugler to sound the alarm, and to sound it with all his strength, while at the same time a blank charge was fired as a warning to the other ships to be on the alert. Immediately afterward a bugle was heard shrilling from the Almirante Cochrane, and this was taken up by every ship in the squadron, for the whole fleet was now thoroughly alarmed and on the alert.
For a few moments a state nearly approaching to panic reigned aboard the flagship; but the men were quickly at their quarters, and every gun in the ship was promptly trained upon the position indicated by Douglas. It was too dark to enable the gunners to aim with precision, but the sound guided them to some extent, and suddenly a perfect volcano of machine-gun fire broke out on board the Blanco Encalada, followed by a hoarse scream of agony from the torpedo-launch. An iron bucket was partly filled with paraffin and this was lighted as a flare, throwing a lurid glare over the sea and disclosing plainly to view a couple of rapidly approaching launches, each of which carried a spar over her bows, from which a torpedo was suspended, the launches heading directly for the Blanco Encalada. But upon the nearest launch the effect of the flagship’s fire was terrible. The helmsman had been cut nearly to pieces by the hail of bullets, and he now hung dead over the tiller of the little steamer, which was consequently yawing wildly about. The remainder of her crew were in the well abaft the boiler, some lying huddled up on the floor, while others hung loosely, like half-empty sacks, over the launch’s bulwarks, their arms trailing in the water. Indeed it appeared as though the Blanco Encalada, by a lucky fluke, had concentrated her whole fire upon that one devoted craft. For a moment it appeared as though the little steamer, with her crew of dead, would still effect her purpose, for the torpedo was still intact at the end of its spar, and the launch was heading straight for the battleship; but just at the last moment the corpse of the helmsman was jerked from the tiller by the motion of the sea, and the launch’s head immediately fell off a point or two. She rushed past the Blanco Encalada’s bows, missing them by no more than a few feet, and a few minutes later a deafening report from the shore told those on board the flagship that the torpedo-launch had rushed at full speed upon the rocks, thus exploding her torpedo and blowing herself to pieces.
The second launch, which had been steaming about a hundred yards astern of her consort, had miraculously escaped that whirlwind of shot, and now, seeing the fate of her consort, she described a wide circle, and headed away to the north-west, out of the bay, at full speed. In a few minutes she would be beyond the circle of light thrown by the flagship’s brazier of fire, and would be in safety; but she was not to escape so easily. The Blanco Encalada’s gunners carefully laid their machine-guns on the craft, and opened a furious fire upon her. The rattle of the Nordenfeldts sounded like a continuous roar of thunder, and the stream of fire from their muzzles itself illuminated the darkness of the night with a fitful glare.
The gunners got the range almost immediately, and those on board the flagship could see that the water was lashed into foam round the launch by the pelting rain of missiles. There was no escape from that iron hail, not even for those desperate members of the crew who dived overboard, for the men of the Blanco made a target of every face that appeared upon the surface of the water.
Then the end came, suddenly and dreadfully. A bullet must have passed in advance of the launch and struck the torpedo itself, for the onlookers saw a dazzling burst of whitish-blue flame, which was followed by a deafening, stunning explosion, and the launch seemed to disappear, as if by magic, in a tornado of flame, for not even a fragment of her appeared on the water afterwards. The roar of the machine-guns at once ceased, and every man on board the ship wiped away the cold sweat of fear which had burst out on his forehead at the prospect of being torpedoed; for there is no arm in the naval service so dreaded by the sailor.
Tranquillity was now gradually restored, and half an hour later peace once more reigned; but not a single man in the whole squadron could bring himself to go below again until day dawned. On every ship huge fires were lighted, and boats were sent to patrol the fleet in order to prevent a repetition of the occurrence; but it was not until daylight revealed a sea empty of craft save those of the Chilians that the fearful strain of suspense was relaxed.
Admiral Williams personally thanked Douglas and O’Meara for their quick action, which had undoubtedly saved the flagship, and very probably some of the other vessels of the squadron. He also questioned the lads closely, in order to ascertain whether they had heard or seen anything which would furnish a clue to the nationality of the occupants of the launches, but they could tell him nothing; and the Admiral was at length driven to the conclusion that his assailants must have come down the coast from Antofagasta, and must have consisted of a couple of the ancient torpedo-launches which the Bolivians were known to possess, but which Williams had left out of his calculations as being too unimportant to be taken into consideration. How dearly this oversight might have cost him has already been seen.
The following, or rather, the same morning, the ships’ boats were lowered, and, assisted by flat-bottomed craft from the shore, began the work of embarking the remainder of the troops. It continued during the whole morning, and by mid-day the balance of the military contingent was distributed among the ships, which then got up their anchors and turned their bows to the northward once more, still under easy steam for the benefit of the old and rotten Esmeralda, two of whose boilers were so eaten away by rust as to be useless. A particularly keen look-out for hostile ships was kept, in view of the alarming incident in Caldera Bay, but nothing of a suspicious character was sighted, and on the evening of the 13th of February the fleet anchored before the town of Antofagasta, the principal seaport of Bolivia, lying in a half-circle at a distance of about a mile and a half from the shore.
The obnoxious tax was to come into force on the following day, if Bolivia adhered to her original resolution; and Admiral Williams had orders that, should such prove to be the case, he was to seize the Custom House, invest the town, and in the event of resistance being offered, to bombard it. Chili did not intend to submit tamely to the high-handed action of Bolivia, which constituted a serious and intolerable infraction of treaty.
