Troilus and Cressida [5] -

“Following the theft of Helen from Menelaus by the Trojan Paris, the Greek army has laid siege to Troy for seven years. Its energies are now paralysed by squabbles between its commanders, the chief of these having raged between Agamemnon and Achilles, who has retired to his tent with his friend Patroclus and refused to fight. Meanwhile, Calchas, the father of Cressida has defected from the Trojan to the Greek camp, leaving behind Cressida's uncle Pandarus to act as her guardian. As she falls in love with Troilus, the son of the king, it is only a matter of time before the opposing sides of this war must inevitably meet, entangling all concerned in the conflicting obligations they must try to meet.” - Shakespeare's Globe Theatresee less
