"Into the house!" shouted Jack.

The men burst into the building. Taking advantage of the cover afforded by heaps of shattered masonry, woodwork, and furniture, they stood firm to meet the attack of the French, who, as soon as the dust and smoke began to clear, charged furiously up to the ruined wall. Their front ranks were mowed down by the withering fire of the Spaniards, but the gaps were instantly filled, and the undaunted enemy pressed on again. The volumes of smoke and the heaped wreckage of the house made it difficult sometimes for the combatants to see one another. For the moment the advantage was with the Spaniards. Nothing could dislodge them from behind their barricades of brickwork, furniture, even piles of books. But the French were swarming in at the other end of the block of buildings, and some, mounting on heaps of débris, were able to fire over the heads of the men in front of them into the Spanish position. Jack saw that with the fall of the party-wall of Vallejo the remains of the roof and front wall of the house beyond had also come down. Profiting by this circumstance, he sent a number of men on to the roof of Tobar, whence they were able to enfilade the French marksmen. They were assisted by a strong fire from the front barricade, where Antonio, now the leader of the guerrilleros, was doing yeoman service. Finding that after repeated charges no impression had been made on the Spanish defences, the French drew back disheartened, and, unwilling to face the risk of meeting again such heavy losses, made no further serious attempt during the morning to carry the position. The action degenerated into a fitful exchange of musket-shots, whenever a Frenchman or a Spaniard incautiously exposed himself.

"Well done, hombres!" said Jack, who had gone from point to point cheering them on, reinforcing weak spots, narrowly escaping the enemy's bullets as he moved at times across the line of fire. He had been quick to mark instances of special bravery or skill, and the few words of praise he spoke nerved the ardent Spaniards to still more strenuous exertions.

In the afternoon, as he was resting in the Casa Alvarez, news was brought that the French had been seen clearing away parts of the débris in the ruins at the farther end of the Vallejo block.

"What does that mean?" he exclaimed, starting up. "They will only expose themselves to direct fire from the roofs and the barricade."

Hastening with Don Cristobal to the roof of the Casa Tobar, he sought for an explanation of the new movement. Suddenly it occurred to him: the French were about to bring the gun, which had been driven away from the angle of the street, to a position whence it would bear upon Vallejo, and the work they were doing was for the purpose of clearing away anything that might intercept its fire.

"We can't hold Vallejo against a bombardment," he remarked. "Stay! Perhaps Don Casimir would lend us a gun from his ramparts. Things have been pretty quiet with him lately. Antonio, run off with twenty men and ask Don Casimir to let you have an eight-pounder, with grape and round-shot. If we can get a gun to bear, Señor, the work the French are doing will assist us as much as themselves."

"Can we mount the gun?" asked Don Cristobal, descending with Jack.

"We can but try. 'Where there's a will there's a way', as we say in England."

Twenty minutes later Antonio returned with his men, hauling the eight-pounder briskly along towards the barricade. It was easily taken into the patio of the Casa Vallejo, but to move it thence into a position facing the French would necessitate the breaking of the wall of one of the ground-floor rooms.
