Caesar's masterly manipulation allows a triumphant Roman recapture of Sinessa. Gannicus stays behind to cover the retreat of Spartacus and most warriors onto the icy mountain ridge, where they are pinned down in dire conditions. Crassus rewards Heracleo with gold and 'traitor' Laeta, but Gannicus manages during his escape with Sibyl to kill the pirate captain and rescue the new 'slave'. Crassus orders Tiberius, who hoped to resume deputy command, to preside over the celebration of Caesar's victory and bribes senator Metellus to share the looting of the whole city. Instead of befriending Caesar, jealous Tiberius tries to trick his rival during the bloody execution of prisoners, but Caesar triumphs again.
