“Let’s—oh, do let’s cross over to the other side,” cried Punch. “There’s two places there where we could get shelter;” and he pointed to a couple of heaps of stone that diagonally were about forty yards in advance.

But as he spoke there was another rush of their friends round the curve, with the same tactics, while those who had come before now dashed across the great passage and occupied the two rough stoneworks themselves.

“Too late!” muttered Punch amidst the roar of musketry which now seemed to have increased in a vast degree, multiplied as the shots were by echoing repetitions as they crossed and recrossed from wall to wall.

“No!” shouted Pen. “Fire!” For half-a-dozen French chasseurs suddenly came running into sight in pursuit of the last little party of the Spaniards, dropped upon one knee, and, rapidly taking aim, fired at and brought down a couple more of the retreating men.

There was a sharp flash from Punch’s piece, and a report from Pen’s which sounded like an echo from the first, and two of the half-dozen chasseurs rolled over in the dust, while their comrades turned on the instant and ran back out of sight, followed by a tremendous yell of triumph from the Spaniards, who had now manned the two heaps of stones on the other side.

There was another yell, and another which seemed to fill the entry to the old mine with a hundred echoes, while as the boys were busily reloading a figure they did not recognise came running towards their coign of vantage at the top of his speed.

“Quick, Punch! An enemy! Bayonets!” cried Pen.

“Tain’t,” grumbled Punch. “Nearly ready. It’s Contrabando.”

The next minute the Spaniard was behind them, slapping each on the back.

“Bravo! Bravissimo!” he shouted, making his voice heard above the enemy’s firing, for his men now were making no reply. “Continuez! Continuez!” he cried, and then dashed off forward again and, heedless of the flying bullets, crossed to where his men were lying down behind the two farther heaps of stones, evidently encouraging some of them to occupy better places ready for the enemy when they made their attack in force.
