Iphigenia is thrilled at the prospect of marrying one of the great heroes of the Greek army, but she, her mother, and the ostensible groom-to-be soon discover the truth. Furious at having been used as a prop in Agamemnon's plan, Achilles vows to defend Iphigenia, initially more for the purposes of his own honour than to save the innocent girl. However, when he tries to rally the Greeks against the sacrifice, he finds out that "the entirety of Greece"—including the Myrmidons under his personal command—demand that Agamemnon's wishes be carried out, and he barely escapes being stoned.
