How a forgotten siege in 409 BC ended the dominance of a Greek city
The Battle of Selinus was a brutal turning point in the Second Sicilian War. When the Dorian Greeks of Selinus refused Carthaginian peace terms, they triggered a massive siege. Carthage, under Hannibal Mago, deployed advanced siege technology that shattered the city’s defenses and forever altered the balance of Mediterranean power.
In 409 BC, the city of Selinus found itself isolated after years of aggressive expansion against its neighbor, Segesta. Segesta, seeking survival, submitted to the Punic hegemony of Carthage. Hannibal Mago, a king of the Magonid family, saw an opportunity to secure Western Sicily. He initially attempted diplomacy, proposing a ceasefire, but the Selinute council rejected the offer, effectively sealing the city's fate.
Carthage lacked a standing army, so Hannibal mobilized a diverse force of mercenaries and levies from Africa, Sardinia, and Spain. While ancient accounts claimed 120,000 men, modern estimates suggest a more realistic strength of 30,000 to 40,000 soldiers. They arrived at Selinus with sophisticated siege equipment, including six wooden towers and iron-plated battering rams, which proved far superior to the defensive tactics of the Greeks, who had little experience with such warfare.
The siege lasted ten days. Despite the Selinute citizens mounting a desperate defense—with women and the elderly hurling tiles and bricks from rooftops—the Carthaginian towers cleared the walls of defenders, allowing the rams to create breaches. After the walls fell, a brutal nine-day street-by-street battle ensued. By the time the fighting ceased, 16,000 Greeks were dead, 6,000 were imprisoned, and only 3,000 managed to escape to Akragas. The city was sacked and never regained its former status.
This conflict highlighted a significant disparity in military capability. While Athens was considered the most formidable in siege warfare among Greek states, their skills were reportedly primitive compared to the expertise of Asian and African powers. The fall of Selinus effectively ended its influence, serving as a stark reminder of the shifting geopolitical landscape in Sicily as Carthage asserted its dominance over the Western Mediterranean.
