How Sulla’s outnumbered Roman legions crushed a massive Pontic army at Chaeronea in 86 BC
In 86 BC, Roman general Sulla faced a Pontic force vastly outnumbering his own. Despite the overwhelming odds, Sulla used clever field fortifications and tactical positioning to secure a decisive victory. The battle remains a masterclass in military discipline, though the official Roman casualty reports were likely heavily exaggerated.
The Battle of Chaeronea in 86 BC pitted Sulla’s Roman forces against the army of Mithridates, commanded by Archelaus and Taxiles. Estimates of the Pontic strength vary wildly, with some sources suggesting up to 120,000 troops, while others, like N.G.L. Hammond, favor a figure of 60,000. In contrast, Sulla commanded roughly 30,000 men, of which fewer than 17,000 were Roman, with the remainder being Greek and Macedonian allies.
Sulla’s tactical brilliance was evident before the fighting began. He secured a commanding position near the Elatean plain and ordered his men to construct defensive palisades and entrenchments. These fortifications proved vital, as they neutralized the Pontic scythed chariots and prevented the enemy's larger cavalry force from enveloping the Roman line. When the Pontic phalanx of freed slaves advanced, the Roman legionaries, fueled by indignation, fought with such intensity that they infiltrated the hedge of pikes, eventually routing the entire enemy army.
The aftermath of the battle was marked by Sulla’s propaganda. He claimed that 100,000 Pontic soldiers were killed while only 14 of his own men were missing, figures that historians consider highly suspect. To cement his victory, Sulla erected trophies on Mount Thurium and the plain near the Molos. Archaeological excavations in 1990 on Isoma Hill uncovered fragments of the Thurium trophy, providing physical evidence of the monument that once honored the gods Ares, Nike, and Aphrodite.
