After the Carthaginian defeat at the Battle of Ilipa, the Turdetani flocked en masse to the Roman banner. Hasdrubal Gisco and Mago, son of Hamilcar, were thereafter confined with their troops to Gades where they were protected from a Roman assault. After the Revolt of Sucro and the Revolt of Indíbil and Mandonio, Publius Cornelius Scipio sent Lucius Marcius Septimus with a small force uninhibited by baggage so as to augment their speed down the Guadalquivir River to the river mouth where he encountered the Carthaginian prefect Hanno (not to be confused with Hanno the Elder) who was attempting to recruit mercenaries for Mago. The Battle of Guadalquivir ensued resulting in another Carthaginian defeat.
