At Port San Julián, Magellan’s fleet—battered by storms and demoralized by hardship—faced open mutiny, as Spanish captains seized control of three ships. The uprising quickly turned violent when the master of the San António, Juan de Elorriaga, was stabbed. Mutineers justified their actions as a defence against Magellan’s tyranny, demanding he share his planned route. Magellan, however, responded shrewdly—luring mutinous crews into negotiations, severing their communications, and launching surprise counterattacks. His loyalists quickly regained control, and the revolt’s leaders met different fates: Cartagena was marooned alongside chaplain Bernard Calmette, Quesada was executed and quartered, and Mendoza was killed in the fighting. The grim punishments cemented Magellan’s authority but at a tall cost, deepening fear and resentment.
