Tom’s suspicions were confirmed, when in another minute a hot fire was again opened, the bullets just clearing the edge of the platform; and directly afterwards the chief and several of his followers sprang up upon it. Once having gained possession of the ground, it was easy enough for the rest. Matters were now becoming far more serious than before. From another opening in the rock, Tom, although still concealed from the Arabs, was able to look down upon the anchorage. “Hurrah!” he exclaimed; “Mr Matson has not been asleep; there comes the boat from the island, and if the slavers are not sharp about getting under way, she’ll have the whole of them; but one or two are pretty sure to be caught.”

As he spoke, the report of a gun was heard, and it was seen that the boat, as she pulled towards the slavers, was firing at them from her bow. The Arabs on the hillside, startled by the sound, looked round; those who were in a position to see what was happening below, shouted to their companions, who speedily began to leap down the rocks; most of those on the platform, in their hurry and fright, springing down a distance by which they ran an imminent risk of breaking their necks; others bounded down the pathway in a mode terror alone could have prompted them to venture on.

“Now’s our time!” exclaimed Desmond, seizing several large stones which lay in the hollow; “if our bullets can’t reach them, these will;” and he and Tom, leaping from under cover on to the platform, while their men kept up a brisk fire, began to pelt the retreating Arabs, three of whom were knocked over, several others having broken their legs or necks in their flight, till the hillside presented the appearance of a battlefield. All this time the midshipmen and sailors were shouting and hallooing at their flying foes. The larger number of the Arabs, however, reached the bottom of the hill unhurt, and were seen hurrying down to the shore, apparently with the intention of shoving off to the dhows to assist their countrymen. They were all collected together, engaged in launching a boat, when a shell plunged right in among them, killing and wounding several. The rest, fearing the visit of another missile, took to flight. The desire, however, of preventing the slaves being captured, either by bringing them on shore or beating off the English, induced them to go back and make a second attempt; but scarcely had they collected when another shell pitched right into the boat, shattering her to pieces, and laying low two more of their number.

This was more than their greed of gain could stand; again they took to flight, following their chief, who made towards the only shady spot in the neighbourhood, where a horse was left tethered. Mounting, he galloped off, followed by the rest of his gang on foot.

The party on the hill were at first doubtful whether they ought to follow the fugitives, as Desmond had suggested. Tom, however, thought that they decidedly ought to prevent any slaves who might be landed from escaping. One of the dhows was seen hoisting her sail. Having cut her cable, she stood out to sea, while the other two, in order to give her a better chance of escaping, commenced firing at the boat, expecting that she would at once attack them. The lieutenant, however, had made up his mind to have all three, and, disregarding their shots, he pulled away after the first, at the same time firing his bow-gun at her rigging. She was a fast vessel, and was leading the boat out of harbour. The other two dhows, seeing this, began to hoist their sails for the purpose of slipping out astern of her. As he might possibly lose all three, the lieutenant now put back, and managed to run on board one of the dhows.

The Arabs fought desperately, and it seemed doubtful who would gain the victory. “I wish we were on board to help them!” exclaimed Desmond; “if I thought we could swim as far, I should propose going off to her.”

“Better stay where we are,” said Tom; “we shall have work enough to do. See, the other dhow is coming round with the intention of running on shore; probably those on board don’t see their friends scampering off, and they hope to re-land their slaves. It is fortunate we are here to prevent them escaping; perhaps they have been so busily engaged that they may not have seen us, and I propose that we hide ourselves behind those rocks out there, and, if the slaves land, we can rush out and surprise them.” The plan suggested by Tom was instantly put into execution. Notwithstanding the opposition of the crew, the dhow attacked by the lieutenant was quickly captured, and again brought to an anchor; when, leaving some of his people on board, he made sail after the first dhow, which there was still a possibility he might overtake. The midshipmen could hear his gun rapidly fired, showing that he was trying to bring down her sail.

The last of the three dhows had now stranded, and the cries and shrieks which arose showed that the Arabs were throwing the unfortunate blacks into the water, and compelling them to make their way on shore. Tom and Desmond agreed that it would be no easy matter to stop the blacks and to fight the Arabs at the same time, as they would be certain to try and make off with as many of the negroes as they could. Looking out from their hiding-place, they saw the beach covered with blacks, who had swum and waded on shore; but the Arabs themselves were waiting on board till all were out of the vessel, intending to come on shore in their boat. Probably they expected that their friends would hurry down and assist them in securing their captives.

Just as the boat left the side of the dhow, the midshipmen, uttering loud shouts, rushed out of their hiding-place; while the blacks, seeing them, ran on either side like a flock of scared sheep. The sailors in vain tried to reassure them; as they had not much time to do it, it was necessary to attack the boat before the Arabs reached the shore. The latter were evidently taken by surprise, and, cramped in the boat, which was tossing about, were unable to use their firearms to any effect. A few shots were fired wildly, and the next instant, as she was thrown on the beach, the midshipmen and their followers, rushing into the water, attacked the crew so vigorously with their cutlasses that half their number were killed or wounded before they could defend themselves; while the rest, as they were dragged out, were made prisoners. The wounded were allowed to lie on the shore, while the rest were secured by ropes, which had been brought on shore to bind any refractory slaves.

No victory could have been more complete. The next business was to stop the blacks, who were hurrying away in different directions. In vain the sailors shouted to them, some persisted in running off into the wilderness; but a considerable number were at length turned back to the seashore, where they all stood crowded together, too much alarmed to know what to do, and gazing at their late masters with astonishment. Still, should they attempt to break loose, it would be no easy task to stop them. Every now and then Tom kept looking out for Mr Matson’s boat, and was not sorry to see her returning, though one of the dhows had escaped.
