Battle of Chaeronea (86 BCE)

Type of action: Ground battle in the First Mithridatic War

Date: 86 b.c.e.

Location: Boeotia, central Greece

Combatants: About 40,000 Romans vs. around 110,000 Pontics

Principal commanders:Roman, Proconsul Sulla (138-78 b.c.e.); Pontic, General Archelaus (fl. first century b.c.e.)

Result: Sulla destroyed two Pontic armies; both sides’ reported casualty figures are improbable

Corruption and oppression made Roman rule hated in Greece and Anatolia. The Social War (91-88 b.c.e.) in Italy enabled King Mithridates VI Eupator of Pontus to conquer territory while posing as a liberator. He eliminated Roman forces in western Anatolia, where the inhabitants massacred resident Italians. Invited by Athens, royal armies occupied Greece in 87 b.c.e.

Consul in 88 b.c.e. and then proconsul, Sulla crossed to Greece, where he besieged and sacked Athens and Piraeus (March 1, 86 b.c.e.). Short on food, Archelaus withdrew from Attica to Boeotia, where he joined another and then a third Pontic army moving south from Macedonia. Sulla followed Archelaus to Chaeronea, where he used entrenchments to prevent his troops from being surrounded and palisades to protect against chariots. Sulla repulsed the Pontic charge, then counterattacked, driving the Pontics from the battle site. The following year, Sulla again defeated the Pontics at Orchomenos.

Significance

In 85 b.c.e., Mithridates signed the Treaty of Dardanus, in which he agreed to vacate Greece and Roman possessions in Anatolia, surrender seventy warships, and pay an indemnity. Sulla’s pillage of Athens contributed to the Romans’ reputation as barbarians, but the campaign revealed him to be a skillful commander. He returned to Italy in 83 b.c.e., eliminated opponents by battle and proscription, and became dictator.
