The burly savage blustered and protested, but he was made to step into his canoe, which had been paddling alongside, and Hemming signified to him clearly that he must take himself off. They observed him watching them for some way; then he hauled up his canoe, and taking a path inland, they saw no more of him. They had pulled on for half an hour or more when Murray caught sight of a board floating in the water. He could scarcely account for the impulse which made him steer towards it and pick it up. His eye brightened as he looked at it.

“Hurrah!” he shouted joyfully; “hurrah! Jack Rogers is alive; here is a note from him. There is no doubt about it. It is short though—he says, ‘A prisoner. Up south branch. Jack R.’” The shout was taken up by his own crew and the crews of all the other boats, and the banks of the stream rang with their loud hurrahs. This brief notice instigated all hands to make still greater exertions to try and recover Jack, wherever he might be. On they went; reach after reach of the winding river was passed, and they had got a long way up, higher than any of them had been before, when a shot, seeming as if it came out of the bank, flew over their heads. Another and another followed.

“We are just in front of the pirates’ battery,” exclaimed Hemming; “on, lads, on! we’ll storm it without delay.” The seamen required no further encouragement. A shower of rockets was first fired into the enemy’s fort, and then on they dashed, in spite of the heavy fire of musketry, as well as of grape-shot and langrage, which was opened on them in return. To their rage and disappointment, the boats stuck on the mudbank just outside the stockades, which they only then discovered. Many of the seamen leaped out of the boats and attempted to wade onwards, but they either at once sank into the mud or fell forward into the deep ditch, where several were shot down before they could be rescued by their comrades, while others were drowned or smothered in the mud. It was horrible work. An enemy whom they despised was close to them, and yet could not be got at. Hemming, his heart burning with anger and grief at the loss of so many poor fellows and the almost hopelessness of success, ordered the boats to shove off, with the intention of making an attack on some other part of the fort. The blacks continued firing away under cover without much fear of being hit in return. It was melancholy to have to retire, and to see the bank, from off which the water had begun to recede, strewed with the bodies of those who a few minutes before were as full of life and energy as themselves. Before getting to any great distance, Murray thought he saw a channel to the right, which must run near the fort. He pointed it out to Hemming, who told him to lead the way. He was right; the negroes had neglected to fortify it, and in a few seconds the boats were close up to the stockades. Not a moment was lost in storming them and hauling them down. In rushed the gallant bluejackets, led on by Hemming, Murray, Adair, and other officers, and at length they got their black enemy face to face.

“There’s Rogers, there’s Rogers!” shouted Murray and Adair, for they both saw him at the same time. They were certain of it, though his features were considerably begrimed with powder, smoke, and dirt. This was incentive enough to make them push on with still greater haste, had they not been eager to punish the abominable slave-dealers and their crew of ruffians. The brave fellows little knew the terrible trap prepared for them. Murray and Adair had sprung on ahead, and believed that in another minute they would have rescued Jack from the grasp of his captors, when they felt themselves suddenly pulled back by Hemming and Will Needham.

“Back, back, lads, back!” sang out the lieutenant. At that moment up ascended right before them a mass of earth and stones and wood, with a dense cloud of smoke and dust, accompanied by a terrific roar, and they felt themselves lifted off their feet and sent heels over head, while down upon them came showering all the more solid portions of the above-mentioned materials about their ears, as they lay half stunned and stifled and vainly endeavouring to rise. Another foot in advance, and they would have been blown to destruction. Hemming had seen the old Spaniard fire his pistol into the tub, and guessed what was coming. Murray and Adair felt themselves very much hurt, so indeed were Hemming and Needham; while several poor fellows were maimed or killed outright. The two schoolfellows, after lying stupefied for a few seconds, lifted up their heads and began to crawl out from the mass of ruins which surrounded them.

“Where’s Jack?” exclaimed Murray.

“Where’s Jack?” cried Adair, getting upon his legs and helping Murray, who was hurt more than he was.

These were the first words they uttered. He had not been out of their thoughts, in spite of the dreadful commotion. As the smoke cleared away they caught sight of the group of fugitives, among whom they supposed he was, ascending the hill which rose beyond the fort. They were eager to pursue, but when they looked round and saw so many of their companions disabled, and Lieutenant Hemming himself on the ground, they could not help fearing that pursuit would be hopeless. Still they were moving on, when Hemming, recovering himself, called them back.

“It is of no use, lads,” he cried. “The scoundrels have escaped us this time. See, see, too, we have work here,” As he spoke, flames burst forth out of the barracoon, part of which had been blown up by the mine. The seamen who could stand, wounded or not, rushed forward, led by their officers, to help the miserable slaves. They hacked away desperately to get them free of their manacles, trying to cut through the solid iron or the beams to which the chains were secured. Meantime the hot flames were raging around them, and almost prevented them from performing their work of mercy. Still, in spite of the fire, the heat, and the smoke, and the possibility of being again blown up, the undaunted fellows laboured on. Numbers of the poor slaves had been liberated, and several children had been carried off who would otherwise have been left with their mothers to perish; but at last the terrific element gained the upper hand. The seamen’s clothes were literally scorched off their backs before they would quit the work of humanity on which they were engaged, but even they were at last obliged to retreat, leaving the miserable captives to their fate. Again and again, however, now one, now another, would make a dash in among the flames, and try to haul out some poor burning creature whose imploring cries their tender heart could not withstand. One gallant fellow was killed by the falling of a burning beam before they would desist altogether from their brave efforts.
