“I know nothing of filibuster customs.” The gentleman was disdainful.

“But you are learning quickly.”

“What do you mean, you rogue? I am a leader of armies, not of plundering thieves.”

“Oh, but of course!” Blood's irony laughed in his eyes. “Yet, whatever you may be, I warn you that unless you yield to a demand that I consider just and therefore uphold, you may look for trouble, and it would not surprise me if you never leave Cartagena at all, nor convey a single gold piece home to France.”

“Ah, pardieu! Am I to understand that you are threatening me?”

“Come, come, M. le Baron! I warn you of the trouble that a little prudence may avert. You do not know on what a volcano you are sitting. You do not know the ways of buccaneers. If you persist, Cartagena will be drenched in blood, and whatever the outcome the King of France will not have been well served.”

That shifted the basis of the argument to less hostile ground. Awhile yet it continued, to be concluded at last by an ungracious undertaking from M. de Rivarol to submit to the demands of the buccaneers. He gave it with an extreme ill-grace, and only because Blood made him realize at last that to withhold it longer would be dangerous. In an engagement, he might conceivably defeat Blood's followers. But conceivably he might not. And even if he succeeded, the effort would be so costly to him in men that he might not thereafter find himself in sufficient strength to maintain his hold of what he had seized.

The end of it all was that he gave a promise at once to make the necessary preparations, and if Captain Blood and his officers would wait upon him on board the Victorieuse to-morrow morning, the treasure should be produced, weighed in their presence, and their fifth share surrendered there and then into their own keeping.

Among the buccaneers that night there was hilarity over the sudden abatement of M. de Rivarol's monstrous pride. But when the next dawn broke over Cartagena, they had the explanation of it. The only ships to be seen in the harbour were the Arabella and the Elizabeth riding at anchor, and the Atropos and the Lachesis careened on the beach for repair of the damage sustained in the bombardment. The French ships were gone. They had been quietly and secretly warped out of the harbour under cover of night, and three sails, faint and small, on the horizon to westward was all that remained to be seen of them. The absconding M. de Rivarol had gone off with the treasure, taking with him the troops and mariners he had brought from France. He had left behind him at Cartagena not only the empty-handed buccaneers, whom he had swindled, but also M. de Cussy and the volunteers and negroes from Hispaniola, whom he had swindled no less.

The two parties were fused into one by their common fury, and before the exhibition of it the inhabitants of that ill-fated town were stricken with deeper terror than they had yet known since the coming of this expedition.
