"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.
