Archelaus commanded an estimated 60,000 men, comprising diverse units such as Macedonian-style phalanxes, Greek mercenaries, Oriental troops, and scythed chariots. These elements reflected Pontus' ambition to project power across the eastern Mediterranean. In contrast, Sulla’s forces numbered about 30,000, including hardened Roman legions and allied Greek contingents. Despite the disparity, Sulla's leadership and tactical brilliance turned the tide in favor of Rome.
Sulla carefully selected the battlefield, exploiting its terrain to neutralize the scythed chariots' devastating potential. When the battle began, he employed disciplined formations to withstand the Pontic charge and countered with coordinated infantry assaults. Sulla’s troops quickly advanced, closing ranks to disrupt the phalanxes and overwhelming the chariots before they could wreak havoc. The disciplined Roman veterans, seasoned by earlier campaigns, capitalized on Pontic disarray, delivering precise and relentless blows.
The battle concluded with a decisive Roman victory, inflicting severe casualties on Archelaus’ forces and causing their complete rout. While Pontic losses were staggering, Sulla's forces remained intact, a testament to their superior training and strategy. The victory was not merely tactical but also strategic, as it solidified Roman dominance in Greece and demoralized Pontic forces across the region.
This triumph also bolstered Sulla's political and military standing, enabling him to impose harsh terms on Greek cities that had supported Pontus and secure vital resources for Rome. The Battle of Chaeronea underscored the effectiveness of Roman military doctrine against diverse and numerically superior opponents, marking a turning point in the First Mithridatic War. It reaffirmed Roman hegemony in the Hellenistic world, paving the way for further consolidation of power in the eastern Mediterranean.
