Pontic troops
One of Mithridates generals, Taxiles, and a large force were sent to join up with Archelaus and his forces in the Elatean plains.<ref name=":2">Template:Cite book</ref><ref name=":3">Template:Cite book</ref> Baker cites a Roman army of less than 17,000 thousand, excluding allied troops, and the enemy Pontic army outnumbering those troops 5 to 1, or around 85,000 troops.<ref>Template:Cite book</ref> Delbruck presents both a "supposed" figure of 120,000 troops and a reduced figure of a "more modest" 60,000 Asiatics.<ref name=":0">Template:Cite book</ref> Delbruck further makes comments on the available primary sources and specifically refers to "vague and boastful" memoirs of Sulla which were the primary source that other historians of the time used, such as Plutarch.<ref name=":0" /> Hammond preferred the figure of 60,000 soldiers, which is supplied by Memnon of Heraclea.Template:Sfn The Pontic forces are also said to have had 90 scythed chariots.<ref>Plutarch Life of Sulla 15</ref>
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.<ref name=":5" />
Sulla's troops
Sulla's forces are approximated to have been around 30,000 men,<ref name=":0" /><ref name=":6">Template:Cite book</ref> with Baker commenting that of these less than 17,000 were Romans and the rest were composed of Macedonian and Greek allies.<ref name=":1">Template:Cite book</ref> 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.<ref name=":1" /> The Roman forces were composed of veteran Roman legions and some cavalry.<ref name=":6" /><ref name=":7" />
Geography
Sulla advanced his army from Athens and into Boeotia, where he met up with Hortensius, who had advanced southward from Thessaly, at Philoboetus.<ref name=":2" /><ref name=":3" /> Hortensius himself had moved through the mountains with a guide, intent on avoiding an ambush.<ref name=":2" /><ref name=":3" /> 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.<ref name=":2" /><ref name=":3" /> Baker describes this position as "commanding the Elatean plain and the valley of Cephisus."<ref name=":2" /> Sulla was determined to dictate the time and place of the battle.<ref name=":1" />
Taxiles and his large force had to go north through a defile, before turning into the narrower valley, between Orchomenos and Chaeronea to meet up with Archelaus and his forces.<ref name=":2" /><ref name=":3" /> The consequence of this was that once Taxiles and his forces arrived, it became impossible for the forces to retreat and instead had to stand and fight.<ref name=":2" /> This force was encamped in the valley in a position which allowed the commanders to watch the Roman army.<ref name=":1" /> Archelaus intended to pursue a war of attrition, Taxiles with his far larger force, however, was determined to defeat the Romans in battle and insisted on an engagement and, given the circumstances, Archelaus was in no position to refuse.<ref>Template:Cite book</ref>
Prelude
The Pontic forces, encamped in the valley, sent out numerous foraging parties which plundered and burned the countryside.<ref name=":2" /><ref name=":3" /> Sulla was unable to defend the region with his far smaller force and instead was forced to stay camped up on the hill.<ref name=":2" /><ref name=":3" /> Instead of remaining idle, Sulla ordered his men to dig entrenchments on the flanks to protect against possible envelopment by cavalry and also ordered the construction of palisades in the front to defend against the chariots.<ref name=":8">Template:Cite book</ref> The exercise was twofold in intention, first Sulla sought to ensure the discipline of his soldiers and second, he hoped to tire the soldiers out so that they were more willing to battle.<ref name=":5">Template:Cite bookTemplate:Dead link</ref><ref name=":4">Template:Cite book</ref> 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.<ref name=":4" /> The men agreed to this task, Archelaus had already marked the position for his own men and it became a race between Archelaus' and Sulla's men to occupy the position first.<ref name=":4" /> 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.<ref name=":4" />
Order of battle
For Rome, Sulla was in command of the right flank of the Roman army, the legate Murena on the left, Hortensius and Galba commanded the reserve cohorts in the rear with Hortensius on the left and Galba on the right.<ref name=":3" /><ref name=":7">Template:Cite book</ref> Finally, Gabinius and one full legion were sent to occupy the town of Chaeronea itself.<ref name=":7" /> For Mithridates, Archelaus was in command.<ref name=":7" />
Battle
Sulla opened the engagement with an apparent retreat, leaving one unit under Gabinius to occupy and defend the town of Chaeronea and having Murena retreat back onto Mount Thurium, while he himself marched alongside the right bank of the river Cephisus.<ref name=":7" /> Archelaus in response marched forth to occupy a position facing Chaeronea and extended a flanking force to occupy Murena's troops at Thurium.<ref name=":7" /> Sulla linked up with Chaeronea and extended the Roman line across the valley.<ref name=":7" /> 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.<ref name=":7" /> By this point, Sulla had taken up his position on the right and the battle began.<ref>Template:Cite book</ref>
Murena, assisted by the force of natives from Chaeronea, cautiously launched an attack against the right flank, which, being attacked from above, was forced down the hill with disastrous consequences and possibly up to 3,000 casualties.<ref name=":3" /><ref name=":9">Template:Cite book</ref> In exchange, the Pontic chariots charged forth against Gabinius in the centre, who withdrew his troops behind the defensive stakes he had prepared, which stymied the chariots.<ref name=":9" /> The barrage of Roman javelins and arrows then brought down many of the chariots and caused the rest to retreat in panic. Many of the survivors crashed into the phalanx advancing behind them, leaving it vulnerable to attack.<ref name=":8" />
The Roman legions then came out of their entrenchment to face the Pontic phalanx of freed slaves, who were prevented from coming to a full charge by the field fortifications the Romans had in place.<ref name=":10">Template:Cite book</ref> The legionaries, indignant at having to fight against slaves instead of free men, fought with a terrible fury. They parried the enemy's long pikes with their short swords and shields and in some cases simply grappled them away with their bare hands.<ref name=":10" /> In the end the barrage of stones and bolts from the Roman catapults so disordered the phalanx that the Roman swordsmen were able to infiltrate the hedge of pikes and rout it.<ref name=":11">Template:Cite book</ref>
In the meantime, Archelaus continued extending his line rightward to outflank Murena on the Roman left wing.Template:SfnTemplate:Sfn Hortensius, with the reserve cohorts under his command, came to Murena's rescue, but Archelaus, with 2,000 cavalry, promptly wheeled and pushed him back to the foothills, whence Hortensius's force stood isolated and in danger of being annihilated.Template:SfnTemplate:Sfn Seeing this, Sulla raced across the field with his cavalry from the Roman right which was not yet engaged, forcing Archelaus to withdraw.Template:SfnTemplate:Sfn The Pontic commander now took the opportunity to ride against the weakened Roman right, left vulnerable by Sulla's absence, and at the same time left Taxiles with the bronze-shields to continue the attack on Murena, who was now exposed due to the retreat of Hortensius.Template:Sfn
Sending Hortensius with 4 cohorts to reinforce Murena, Sulla quickly returned to the right with his cavalry, bringing also one cohort from Hortensius' force and another two from (presumably) the other reserve under Galba.Template:Sfn 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.Template:SfnTemplate:Sfn The centre began advancing forward being led by Gabinius who was slaughtering the enemy troops.<ref name=":11" /> Seeing that Murena on the opposite wing was also successful, Sulla ordered a general advance. The entire Pontic army routed, and the commander Taxiles fell into Roman hands, while Archelaus escaped with what remained of his force to Chalcis.Template:Sfn It was said that only 10,000 Pontic soldiers were able to save themselves, and although this is probably an exaggeration, their losses were nonetheless substantial.Template:Sfn Sulla reported that 100,000 of Archelaus' troops were killed, that 14 of his own were missing at the end of the battle and that two of those made it back by the next day.<ref name=":5" /> These figures are, however, called into question as being wholly unconvincing.<ref name=":0" /><ref name=":5" /> Despite the odds, however, the Romans had emerged victorious.<ref name=":12">Template:Cite book</ref>
Aftermath
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. These trophies are mentioned by Plutarch and Pausanias,<ref>Plutarch, Life of Sulla 19.9-10; Pausanias 9.40.7</ref><ref>Template:Cite journal</ref> and seem to be depicted on coinage issued by Sulla after the battle.<ref name="Ieradi">Template:Cite journal</ref> Several fragments from the Thurium trophy were uncovered on Isoma Hill by archaeologists in 1990. It was a square base of whitish-gray marble with a double rebate at the bottom and a torus moulding on top, which supported an unfluted column, which would probably have culminated in a stone sculpture of a panoply (this was not found, but is indicated by parallels, depictions of a pair of trophies on Athenian coinage minted after the battle, and one has been found from this period at Orchomenus). An irregularly-spaced inscription on the front of the base reads: Template:Verse translation Plutarch, who came from Chaeronea, reports that the trophy was also inscribed with Sulla's name and the names of the gods Ares, Nike, and Aphrodite (= Mars, Victoria, and Venus), but this inscription does not survive.<ref>Template:Cite journal</ref>
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.<ref name=PMM77>Philip Matyszak, Mithridates the Great: Rome's Indomitable Enemy, p. 77.</ref> 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.<ref name=":3" /><ref name=":12" /> Flaccus and Sulla met at Melitaea in Thessaly, though neither army made a move, both armies set up camp and waited for the other to attack.<ref name=":13">Template:Cite book</ref> No attack came, and after some time Flaccus' soldiers began to desert in favour of Sulla, at first slowly but with time in increasing numbers, eventually Flaccus had to break camp or lose his entire army.<ref name=":13" /> 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. The Mithridatic army then embarked and sailed to Chalcis from where they marched back into Boeotia.<ref name=":3" /><ref name=":5" /><ref name=":13" /> Both Sulla and Flaccus were aware of these developments, so, rather than waste Roman troops to fight each other, Flaccus took his soldiers and headed for Asia Minor while Sulla turned back to face Archelaus once again.<ref name=":14">Template:Cite book</ref> 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.<ref name=":14" /> Here, Sulla once more, and once again outnumbered, faced off against Archelaus at the Battle of Orchomenus.<ref name=":8" />
