After the First Punic War, Carthage is unable to fulfill promises made to its army of mercenaries, and finds itself under attack. The fictional title character, a priestess and the daughter of Hamilcar Barca, the foremost Carthaginian general, is the object of the obsessive lust of Matho, a leader of the mercenaries. With the help of the scheming freed slave, Spendius, Matho steals the sacred veil of Carthage, the Zaïmph, prompting Salammbô to enter the mercenaries' camp in an attempt to steal it back. The Zaïmph is an ornate bejewelled veil draped about the statue of the goddess Tanit in the sanctum sanctorum of her temple: the veil is the city's guardian and touching it will bring death to the perpetrator.
Chapter 1. "The Feast". During a victory banquet, the mercenaries destroy Hamilcar's garden for sport in his absence. Hamilcar's daughter Salammbô tries to quell the riot. Matho falls in love with her. The slave Spendius is released, and he tries to persuade Matho to take Carthage for the mercenaries.
Chapter 2. "At Sicca". The mercenaries leave the city unpaid and travel to Sicca. Later, Hanno comes and speaks to the mercenaries about delays in recompensing them, but he is driven off when Zarxas arrives and tells them of a treacherous massacre of 300 slingers who had stayed behind.

Chapter 12. "The Aqueduct". The Carthaginians return to their city with the mercenaries in pursuit. Spendius cuts off the water supply to Carthage.
