7. Mors Indecepta

Complete story — includes the ending

With the rebel forces trapped on an impassable, snowbound ridge, Spartacus and Crixus argue with each other over the method of escape. Crassus is confident the trench and palisade he had secretly built will contain Spartacus's army and successfully sets a trap by advancing his general's tent perilously close. To see his debts paid, Caesar accepts being relegated to lower command, while Tiberius is reinstated as Crassus's right hand general. Meanwhile, Kore conspires with Caesar to expose Tiberius's rape, but hearing her lover admit that his paternal pride will forgive any filial flaw, decides instead to defect to the rebel camp. There Spartacus overcomes Crixus's impatience, which peaks at a bloody brawl. A snow storm kills a thousand rebels, but their frozen bodies are used to bridge the trench, allowing the living to break free and escape again.
