"Now, hombres," he said, "when the mines explode, the French in the houses will be destroyed, and those behind them dismayed. We must seize that very moment to rush into the Casa Vega. I shall go first. You must follow close upon me as rapidly as you can. I intend to make for the guns. We shall spike them. We shall then rush back through the ruins and the houses beyond the Casa Vallejo and take the French there in the rear. Don Cristobal will still defend his barricade. Antonio here will hold the rest of you in readiness to sweep upon the French in Vallejo and the street. If I am overcome, and you cannot hold the second barricades, retreat to the Casa Alvarez and fight to the death." The Spaniards were eager to start, and almost too impatient to wait for the explosion. When that occurred, the larger débris hurled into the air had scarcely reached the ground before Jack, followed by his devoted fifty, dashed through the dust that was swirling in vast eddies from the ruins. Entering the Casa Vega by a low side doorway, almost suffocated by the pungent fumes and the clouds of dust, they scrambled through the ruins, springing over stones and beams, broken furniture, burning draperies, every man taking his own course and trying to avoid impeding his comrades. A few seconds brought them to what had been the party-wall of the house. Bearing to the left, Jack dashed into the charred ruins of the adjoining house, through the midst of a few Frenchmen who, injured but not killed by the explosion, were crawling painfully away. A glance to the right!—he saw that the next clearing was still held by the force supporting those who had rushed the houses; but they were in no sort of order, having scattered to seek shelter from the beams and stones that had descended upon them as from the crater of a volcano. A glance in front!—across the narrow street, in the wrecked house nearest the gun, Jack saw in an instant that he had a more formidable foe to reckon with. The French there, some 150 in number, had not been affected materially by the explosion; but it had taken them by surprise, and for the moment they were at a loss what they should do. Before they could realize what was happening, a band of fifty fierce yelling Spaniards, led by a young officer with sword in one hand and pistol in the other, was among them. A score fell at the first onset; the rest scattered to right and left of the Spaniards, and by the time they had collected their wits, and perceived how small was the party engaged in this desperate sortie, Jack and the first of his men were already engaged with the gunners. The onslaught was so sudden, and Jack was so intent on the work in hand, that he was scarcely conscious of what happened until afterwards. One of the gunners, in the urgency of the moment, picked up a linstock and raised it as a kind of club. Jack sprang straight at him, toppled him over by the mere force of his
