Why did Sparta execute the entire male population of the small town of Hysiae?
In 417 BC, the Peloponnesian War took a brutal turn. Following a major defeat at Mantinea, the Spartan king Agis II launched a punitive campaign against Argos. While the city itself held firm, the nearby fortress of Hysiae was not so lucky, leading to a grim historical footnote.
The conflict at Hysiae occurred in 417 BC, shortly after the Spartan victory at Mantinea. The tension began when an Athenian force, led by Alcibiades, intervened in Argos to expel a pro-Spartan faction and install a democratic government. In retaliation, King Agis II marched into Argive territory. Although he failed to breach the city of Argos, he successfully demolished the walls the Argives were building toward the sea, effectively cutting off their strategic expansion.
The fate of Hysiae remains a stark example of ancient warfare's ruthlessness. According to the historian Thucydides, who served as a soldier during the Peloponnesian War, the Spartans captured the town and took its male citizens as hostages. These men were subsequently executed. Diodorus Siculus, writing over two centuries later in the 1st century BC, corroborates the destruction of the fortress and the killing of its male inhabitants. The event highlights the volatile nature of the Peloponnesian conflict, where small towns often bore the brunt of larger geopolitical power struggles.
The aftermath of the destruction saw the Spartans leave a garrison at the nearby town of Orneae before withdrawing from the region. This prompted an immediate Athenian response: a force of 40 triremes and 1,200 hoplites was dispatched to neutralize the garrison and reclaim the area. The subsequent Battle of Orneae underscored the ongoing cycle of retaliation between the Athenian and Spartan alliances. While Thucydides provides a contemporary account of these maneuvers, the differing perspectives of ancient historians remind us that even well-documented military actions are often filtered through the lens of time and political bias.
