Certainly, Bob Harvey and his crew would not be able easily to give an account of what had happened during the night on board the brig.Had this half-naked man, who had forced the door of the powder-magazine, and with whom they had struggled, who had six times discharged his revolver at them, who had killed one and wounded two others, escaped their shot? Had he been able to swim to shore? Whence did he come? What had been his object? Had his design really been to blow up the brig, as Bob Harvey had thought? All this must be confused enough to the convicts' minds.But what they could no longer doubt was that the unknown island before which the "Speedy" had cast anchor was inhabited, and that there was, perhaps, a numerous colony ready to defend it.And yet no one was to be seen, neither on the shore, nor on the heights.The beach appeared to be absolutely deserted.At any rate, there was no trace of dwellings.Had the inhabitants fled into the interior? Thus probably the pirate captain reasoned, and doubtless, like a prudent man, he wished to reconnoiter the locality before he allowed his men to venture there.
During an hour and a half, no indication of attack or landing could be observed on board the brig.Evidently Bob Harvey was hesitating.Even with his strongest telescopes he could not have perceived one of the settlers crouched among the rocks.It was not even probable that his attention had been awakened by the screen of green branches and creepers hiding the windows of Granite House, and showing rather conspicuously on the bare rock.Indeed, how could he imagine that a dwelling was hollowed out, at that height, in the solid granite? From Claw Cape to the Mandible Capes, in all the extent of Union Bay, there was nothing to lead him to suppose that the island was or could be inhabited.
At eight o'clock, however, the colonists observed a movement on board the "Speedy." A boat was lowered, and seven men jumped into her.They were armed with muskets; one took the yoke-lines, four others the oars, and the two others, kneeling in the bows, ready to fire, reconnoitered the island.
Their object was no doubt to make an examination but not to land, for in the latter case they would have come in larger numbers.The pirates from their look-out could have seen that the coast was sheltered by an islet, separated from it by a channel half a mile in width.However, it was soon evident to Cyrus Harding, on observing the direction followed by the boat, that they would not attempt to penetrate into the channel, but would land on the islet.
Pencroft and Ayrton, each hidden in a narrow cleft of the rock, saw them coming directly towards them, and waited till they were within range.
The boat advanced with extreme caution.The oars only dipped into the water at long intervals.It could now be seen that one of the convicts held a lead-line in his hand, and that he wished to fathom the depth of the channel hollowed out by the current of the Mercy.This showed that it was Bob Harvey's intention to bring his brig as near as possible to the coast.
About thirty pirates, scattered in the rigging, followed every movement of the boat, and took the bearings of certain landmarks which would allow them to approach without danger.The boat was not more than two cables-lengths off the islet when she stopped.The man at the tiller stood up and looked for the best place at which to land.
At that moment two shots were heard.Smoke curled up from among the rocks of the islet.The man at the helm and the man with the lead-line fell backwards into the boat.Ayrton's and Pencroft's balls had struck them both at the same moment.
Almost immediately a louder report was heard, a cloud of smoke issued from the brig's side, and a ball, striking the summit of the rock which sheltered Ayrton and Pencroft, made it fly in splinters, but the two marksmen remained unhurt.
Horrible imprecations burst from the boat, which immediately continued its way.The man who had been at the tiller was replaced by one of his comrades, and the oars were rapidly plunged into the water.However, instead of returning on board as might have been expected, the boat coasted along the islet, so as to round its southern point.The pirates pulled vigorously at their oars that they might get out of range of the bullets.
They advanced to within five cables-lengths of that part of the shore terminated by Flotsam Point, and after having rounded it in a semicircular line, still protected by the brig's guns, they proceeded towards the mouth of the Mercy.
Their evident intention was to penetrate into the channel, and cut off the colonists posted on the islet, in such a way, that whatever their number might be, being placed between the fire from the boat and the fire from the brig, they would find themselves in a very disadvantageous position.
A quarter of an hour passed while the boat advanced in this direction.
Absolute silence, perfect calm reigned in the air and on the water.
Pencroft and Ayrton, although they knew they ran the risk of being cut off, had not left their post, both that they did not wish to show themselves as yet to their assailants, and expose themselves to the "Speedy's" guns, and that they relied on Neb and Gideon Spilett, watching at the mouth of the river, and on Cyrus Harding and Herbert, in ambush among the rocks at the Chimneys.
Twenty minutes after the first shots were fired, the boat was less than two cables-lengths off the Mercy.As the tide was beginning to rise with its accustomed violence, caused by the narrowness of the straits, the pirates were drawn towards the river, and it was only by dint of hard rowing that they were able to keep in the middle of the channel.But, as they were passing within good range of the mouth of the Mercy, two balls saluted them, and two more of their number were laid in the bottom of the boat.Neb and Spilett had not missed their aim.
The brig immediately sent a second ball on the post betrayed by the smoke, but without any other result than that of splintering the rock.
