In the immediate aftermath of the battle Sulla erected a trophy which he dedicated to the Roman gods Mars, for delivering victory to Rome, and also to Venus, in the spirit of fortune for the luck granted to the Romans. 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. 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. 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. 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. 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. 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. 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. Here, Sulla once more, and once again outnumbered, faced off against Archelaus at the Battle of Orchomenus.
