The Thunderbolt, this is the name of the Black Corsair's glorious craft. It is night and the vessel is sailing with all its lights off in the waters of the Maracaibo’s harbour. Two men exhausted by the strain, their clothes in tatters, are getting close to the Thunderbolt in a lifeboat. The two men, Carmaux and Van Stiller, are buccaneers that managed to escape death by hanging to which they had been sentenced by the Governor of Maracaibo, Van Gould. The two survivors, were part of the crew on the ship of the Red Corsair, the brother of the commander of the Thunderbolt. The Red Corsair is now dangling from the gallows together with his faithful friends, in the main square of the city and is supposed to remain there for at least three days, exposed to the view and the scorn of the whole town. This is what Carmaux and Van Stiller relate to the commander of theThunderbolt, the Black Corsair. The man does not even shed one tear listening to the report of the death of his last brother by the hand of Van Gould, but in the look on his face there is a terrible thirst for vengeance. The Black Corsair decides to get into Maracaibo stealthly, led by the two escaped death by hanging, and to take away his brother's body to give him a proper burial at sea. The three men return in a lifeboat towards the little town, they hide the lifeboat far from the town in a bight behind a promontory near a thick forest of mangroves. The three men make their way in the forest meeting wild animals; they also come up against and capture a soldier of Van Gould's that had been especially put near the bay to stand guard as Van Gould feared the pirates might land there.
