[8] Mithridates' armies were a compound make-up of Greek and Oriental elements, the infantry was made up of Macedonian style phalanxes, with Pontic phalangists for missile units, and the cavalry a combination of horse and scythe-wheeled chariots.
[9] Sulla's forces are approximated to have been around 30,000 men,[1][2] with Baker commenting that of these less than 17,000 were Romans and the rest were composed of Macedonian and Greek allies.
[10] Baker, however, doesn't give a concrete value for the number of Macedonian and Greek soldiers involved in the battle, merely noting a disparity of "over three to one" between the Roman and Pontic troops once the allies are accounted for.
[4][5] Baker remarks that this movement put Sulla in a favourable position, his supplies were secure, wood and water were plentiful, the roads into Thessaly could be watched and guarded with ease, and the hills provided an advantage.
[9][14] When his troops came to him requesting battle, Sulla challenged the men, citing that their new found will to fight was a response to inherent laziness to work, to occupy the hill of Parapotamii.
[14] Baker describes this position as "almost impregnable", the occupier had no choice but to turn eastward towards Chaeronea to advance and if action took place here, one army or the other would be fighting at an angle.
[11] Murena's position was the weakest, possibly untenable, so to strengthen it Gabinius recruited some of the locals to help deal with the danger, a proposition which Sulla approved.
[19] The Romans there were resisting well, and when Sulla arrived they broke through the Pontic line and pursued them towards the Cephissus river and Mount Akontion.
The entire Pontic army routed, and the commander Taxiles fell into Roman hands, while Archelaus escaped with what remained of his force to Chalcis.
[24] In the immediate aftermath of the battle Sulla erected two trophies: one on the plain near the Molos, where Archelaus' forces had been routed, and the other on Mount Thurium to commemorate Homoloichus and Anaxidamus' dislodgement of the Pontic garrison there.
[29] After the battle, Archelaeus fled to the island of Euboea and immediately started using the fleet stationed there to harass his opponents naval traffic and sending raids against the Romans and their allies.
[30] When Sulla arrived at Thebes he held victory games, during which he may have been made aware of the approach of Lucius Valerius Flaccus who had recently landed in Epirus.
[31] Meanwhile, Archelaeus, who had wintered on the Island of Euboea, was reinforced by 80,000 men brought over from Asia Minor by Dorylaeus, another of Mithridates' generals.
[32] Sulla moved his army a few miles to the east of Chaeronea and into position near Orchomenos, a place he chose for its natural entrenchment.
