Patroclus

In Greek mythology, Patroclus was a Greek hero of the Trojan War and an important character in Homer's Iliad. Born in Opus, Patroclus was the son of the Argonaut Menoetius. When he was a child, he was exiled from his hometown and was adopted by Peleus, king of Phthia.

There, he was raised alongside Peleus' son, Achilles, of whom he was a childhood friend. When the tide of the war turned against the Achaeans, Patroclus, disguised as Achilles and defying his orders to retreat in time, led the Myrmidons in battle against the Trojans and was eventually killed by the Trojan prince, Hector. Enraged by Patroclus's death, Achilles ended his refusal to fight, resulting in significant Greek victories.
