Gylippus was the Spartan leader who commanded forces supporting Syracuse during Athens’ Sicilian Expedition.
Athens launched the Sicilian Expedition in 415 BCE, hoping to conquer Syracuse and expand its influence in the western Mediterranean. Sparta sent Gylippus to help the threatened Sicilian city. He organized Syracuse’s defenses, encouraged the creation of counter-walls, and helped coordinate allied Greek troops against the Athenian army.
Gylippus’ intervention was crucial because the Athenian expedition had initially placed Syracuse under severe pressure. The defenders eventually trapped the Athenians on land and destroyed their fleet in the harbor. The Athenian commanders Nicias and Demosthenes were captured and executed, while many soldiers died or were imprisoned in the stone quarries.
The defeat at Syracuse was one of Athens’ greatest disasters in the Peloponnesian War. Gylippus later faced accusations of corruption after returning to Sparta, showing that military success did not protect a commander from political scrutiny.
