Hector, the king of Troy's eldest son, is confident. His sister, Cassandra, is much less so. She has always known that Paris would bring misfortune to the Trojans, and she forces her mother, Hecuba, to admit it. The battle resumes, and when Poseidon gets involved, so too does Zeus, weighing the two sides' fates and favouring the Trojans. The Greeks know that victory is impossible for them without Achilles their great hero. Agamemnon agrees to send a delegation to ask him to return to combat. But will Achilles accept their appeals?
