"Fire!" he cried, and the order was executed as promptly as before.

Ten minutes later not a single pane of glass was left on the island. The stones trembled and burst in pieces; the cannon-balls knocked holes in the walls, and were flattened on the great flags; a dense smoke overhung the fort, and the air was filled with shrieks and threats and groans.

Canolles saw that Monsieur de La Rochefoucauld's artillery was doing the greatest amount of damage. "Vibrac," said he, "do you look out for Ravailly, and see that he doesn't gain an inch of ground in my absence. I am going to our battery."

He ran to the two pieces which were returning Monsieur de La Rochefoucauld's fire, and himself attended to loading and sighting them; in an instant three of the six guns on shore were dismounted, and fifty men were stretched on the ground. The others, who were not anticipating such a resistance, began to scatter and fly.

Monsieur de La Rochefoucauld, trying to rally them, was struck by a fragment of stone, which knocked his sword out of his hands.

Canolles, content with this result, left the captain of the battery to do the rest, and ran back to repel the assault, which was continued by the Navailles regiment, supported by Espagnet's men.

Vibrac had maintained his ground, but had received a bullet in his shoulder.

Canolles, by his mere presence, redoubled the courage of his troops, who welcomed him with joyful shouts.

"Pray pardon me," he cried to Ravailly, "for leaving you for a moment, my dear friend; I did it, as you may see, to dismount Monsieur de La Rochefoucauld's guns; but be of good cheer, here I am again."

As the captain, who was too excited to reply to the jest,—indeed, it may be that he failed to hear it amid the terrific uproar of artillery and musketry,—led his men to the assault for the third time, Canolles drew a pistol from his belt, and taking aim at his former comrade, now his enemy, fired.
