How a city of iron spikes defeated the war elephants of a Macedonian regent
During the chaotic power vacuum following Alexander the Great's death, the regent Polyperchon attempted to crush the defiant city of Megalopolis. Despite deploying advanced siege towers and war elephants, he suffered a humiliating defeat that shifted the balance of power across the entire Macedonian Empire, ultimately reducing him to a minor player.
Following Alexander the Great’s death in 323 BC, his generals engaged in decades of infighting known as the Wars of the Diadochi. By 319 BC, the regency fell to Polyperchon, a choice that infuriated Antipater’s son, Cassander. Seeking to consolidate his authority, Polyperchon marched into the Peloponnese to subdue Megalopolis, a city that had aligned itself with Cassander under the leadership of the veteran commander Damis.
Polyperchon employed sophisticated siege tactics, constructing wooden towers and mining tunnels to collapse the city’s fortifications. When these methods breached the walls, the defenders held firm, forcing the attackers to retreat with heavy losses. In a desperate bid to break the stalemate, Polyperchon deployed his war elephants against the city's makeshift stockades. However, Damis had anticipated this move, outfitting the defenses with iron spikes, hooks, and nails.
As the elephants approached, the animals were severely injured by the hidden hardware, causing them to panic and stampede through Polyperchon’s own ranks. This failure proved catastrophic for the regent's reputation. The defeat emboldened Cassander and his ally Antigonus, who subsequently seized the initiative. With his fleet defeated at Byzantium and his influence waning, Polyperchon was eventually driven from Macedon, marking the end of his status as a primary contender for the empire.
The siege serves as a stark example of how tactical ingenuity could overcome the sheer military might of the Diadochi. By neutralizing the psychological and physical terror of war elephants, Damis not only saved his city but also fundamentally altered the trajectory of the wars that defined the early Hellenistic period.
