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.
The boat now contained only three able men. Carried on by the current, it shot through the channel with the rapidity of an arrow, passed before Harding and Herbert, who, not thinking it within range, withheld their fire, then, rounding the northern point of the islet with the two remaining oars, they pulled towards the brig.
Hitherto the settlers had nothing to complain of. Their adversaries had certainly had the worst of it. The latter already counted four men seriously wounded if not dead; they, on the contrary, unwounded, had not missed a shot. If the pirates continued to attack them in this way, if they renewed their attempt to land by means of a boat, they could be destroyed one by one.
It was now seen how advantageous the engineer’s arrangements had been. The pirates would think that they had to deal with numerous and well-armed adversaries, whom they could not easily get the better of.
Half an hour passed before the boat, having to pull against the current, could get alongside the Speedy. Frightful cries were heard when they returned on board with the wounded, and two or three guns were fired with no result.
But now about a dozen other convicts, maddened with rage, and possibly by the effect of the evening’s potations, threw themselves into the boat. A second boat was also lowered, in which eight men took their places, and whilst the first pulled straight for the islet, to dislodge the colonists from thence, the second manoeuvred so as to force the entrance of the Mercy.
The situation was evidently becoming very dangerous for Pencroft and Ayrton, and they saw that they must regain the mainland.
However, they waited till the first boat was within range, when two well-directed balls threw its crew into disorder. Then, Pencroft and Ayrton, abandoning their posts, under fire from the dozen muskets, ran across the islet at full speed, jumped into their boat, crossed the channel at the moment the second boat reached the southern end, and ran to hide themselves in the Chimneys.
They had scarcely rejoined Cyrus Harding and Herbert, before the islet was overrun with pirates in every direction. Almost at the same moment, fresh reports resounded from the Mercy station, to which the second boat was rapidly approaching. Two, out of the eight men who manned her, were mortally wounded by Gideon Spilett and Neb, and the boat herself, carried irresistibly onto the reefs, was stove in at the mouth of the Mercy. But the six survivors, holding their muskets above their heads to preserve them from contact with the water, managed to land on the right bank of the river. Then, finding they were exposed to the fire of the ambush there, they fled in the direction of Flotsam Point, out of range of the balls.
The actual situation was this: on the islet were a dozen convicts, of whom some were no doubt wounded, but who had still a boat at their disposal; on the island were six, but who could not by any possibility reach Granite House, as they could not cross the river, all the bridges being raised.
“Hallo,” exclaimed Pencroft as he rushed into the Chimneys, “hallo, captain! What do you think of it, now?”
“I think,” answered the engineer, “that the combat will now take a new form, for it cannot be supposed that the convicts will be so foolish as to remain in a position so unfavourable for them!”
“They won’t cross the channel,” said the sailor. “Ayrton and Mr. Spilett’s rifles are there to prevent them. You know that they carry more than a mile!”
“No doubt,” replied Herbert; “but what can two rifles do against the brig’s guns?”
“Well, the brig isn’t in the channel yet, I fancy!” said Pencroft.
“But suppose she does come there?” said Harding.
“That’s impossible, for she would risk running aground and being lost!”
“It is possible,” said Ayrton. “The convicts might profit by the high tide to enter the channel, with the risk of grounding at low tide, it is true; but then, under the fire from her guns, our posts would be no longer tenable.”
“Confound them!” exclaimed Pencroft. “It really seems as if the blackguards were preparing to weigh anchor.”
“Perhaps we shall be obliged to take refuge in Granite House!” observed Herbert.
“We must wait!” answered Cyrus Harding.
“But Mr. Spilett and Neb?” said Pencroft.
“They will know when it is best to rejoin us. Be ready, Ayrton. It is yours and Spilett’s rifles which must speak now.”
It was only too true. The Speedy was beginning to weigh her anchor, and her intention was evidently to approach the islet. The tide would be rising for an hour and a half, and the ebb current being already weakened, it would be easy for the brig to advance. But as to entering the channel, Pencroft, contrary to Ayrton’s opinion, could not believe that she would dare to attempt it.
In the meanwhile, the pirates who occupied the islet had gradually advanced to the opposite shore, and were now only separated from the mainland by the channel.
Being armed with muskets alone, they could do no harm to the settlers, in ambush at the Chimneys and the mouth of the Mercy; but, not knowing the latter to be supplied with long range rifles, they on their side did not believe themselves to be exposed. Quite uncovered, therefore, they surveyed the islet, and examined the shore.
Their illusion was of short duration. Ayrton’s and Gideon Spilett’s rifles then spoke, and no doubt imparted some very disagreeable intelligence to two of the convicts, for they fell backwards.
Then there was a general helter-skelter. The ten others, not even stopping to pick up their dead or wounded companions, fled to the other side of the islet, tumbled into the boat which had brought them, and pulled away with all their strength.
“Eight less!” exclaimed Pencroft. “Really, one would have thought that Mr. Spilett and Ayrton had given the word to fire together!”
“Gentlemen,” said Ayrton, as he reloaded his gun, “this is becoming more serious. The brig is making sail!”
“The anchor is weighed!” exclaimed Pencroft.
“Yes; and she is already moving.”
In fact, they could distinctly hear the creaking of the windlass. The Speedy was at first held by her anchor; then, when that had been raised, she began to drift towards the shore. The wind was blowing from the sea; the jib and the fore-topsail were hoisted, and the vessel gradually approached the island.
From the two posts of the Mercy and the Chimneys they watched her without giving a sign of life; but not without some emotion. What could be more terrible for the colonists than to be exposed, at a short distance, to the brig’s guns, without being able to reply with any effect? How could they then prevent the pirates from landing?
Cyrus Harding felt this strongly, and he asked himself what it would be possible to do. Before long, he would be called upon for his determination. But what was it to be? To shut themselves up in Granite House, to be besieged there, to remain there for weeks, for months even, since they had an abundance of provisions? So far good! But after that? The pirates would not the less be masters of the island, which they would ravage at their pleasure, and in time they would end by having their revenge on the prisoners in Granite House.
However, one chance yet remained;
