Captain Nemo and the Avenger
Captain Nemo's identity is inextricably bound to the warship Avenger, a vessel whose history he recites with solemn precision and whose wreck he visits in a ritual of remembrance and justification. The Avenger, originally named the Marseillais, was a 74-gun ship launched in 1762 that fought in the American Revolutionary War under admirals d'Estaing and de Grasse, notably at the Battle of Chesapeake Bay in 1781. Renamed by the French Republic in 1794, it joined Admiral Villaret de Joyeuse's squadron at Brest. On the 11th and 12th days of the Month of Pasture in the second year of the Revolutionary Calendar—corresponding to June 1, 1868—the ship sank after a heroic battle, its three masts gone, water in its hold, a third of its crew out of action. Rather than surrender, it went to the bottom with its 356 seamen, its flag nailed to the afterdeck, to shouts of "Long live the Republic!" Captain Nemo reveals this history to Professor Aronnax while the Nautilus lies at rest beside the wreck, 833 meters down in latitude 47° 24' and longitude 17° 28'. He concludes with the ship's name: "The Avenger! A splendid name!"
The Roots of Vengeance
The Avenger is not merely a historical relic for Captain Nemo; it is the symbol of everything he has lost and the engine of his implacable hate. When Aronnax presses him on the nationality of the warship that later attacks the Nautilus, Nemo refuses to answer, saying only: "You don't know? Fine, so much the better! At least its nationality will remain a secret to you." But moments before the attack, he shouts at the vessel: "O ship of an accursed nation, you know who I am! And I don't need your colors to recognize you! Look! I'll show you mine!" He then unfurls a black flag, identical to the one he planted at the South Pole. The captain's personal history, hinted at throughout the voyage, crystallizes in this confrontation. He declares to Aronnax: "I'm the law, I'm the tribunal! I'm the oppressed, and there are my oppressors! Thanks to them, I've witnessed the destruction of everything I loved, cherished, and venerated—homeland, wife, children, father, and mother! There lies everything I hate!" This outburst connects the Avenger's republican martyrdom to Nemo's own family tragedy, which the novel's introduction reveals was originally conceived as the slaughter of his entire family by Russian troops during the 1863 Polish Uprising—a political context that Verne's publisher forced him to obscure.
The Act of Retribution
The sinking of the warship is the culmination of Nemo's vengeance and the moral crisis of the novel. When the unidentified vessel begins cannonading the Nautilus, Nemo refuses to let Ned Land signal for rescue, knocking the harpooner to the deck. He then maneuvers his submersible below the warship's waterline, where its armor does not protect it, and drives the Nautilus's steel spur through its hull "like a sailmaker's needle through canvas." Aronnax watches in horror as the ship sinks, its decks covered with "dark, quivering shadows," its crew leaping into the shrouds and clinging to the masts before being dragged under by "fearsome eddies." Nemo watches until the end, then retreats to his stateroom, where he kneels before a portrait of a young woman with two children and melts into sobs. The act of vengeance is complete, but it brings no peace—only the captain's final, anguished cry: "O almighty God! Enough! Enough!"
Thematic Significance
The relationship between Captain Nemo and the Avenger transforms the Nautilus from a vessel of scientific exploration into an instrument of political retribution. The Avenger's history as a ship of the French Republic that chose death over surrender provides Nemo with a heroic precedent for his own war against oppression. Yet the novel's conclusion leaves the moral calculus unresolved: Nemo's vengeance, however justified by his personal losses, makes him an executioner rather than a liberator. The manuscript he prepares, containing his life story and sealed in an unsinkable contrivance, suggests that he recognizes the need for his actions to be judged by posterity. The Avenger thus stands as both the inspiration for Nemo's crusade and the warning of its tragic cost.
