For Dorylaüs, having put in at Chalcis with a large fleet, on which he brought eighty thousand of the best trained and disciplined men in the army of Mithridates, at once burst into Boeotia and occupied the country. He was eager to entice Sulla to battle, disregarding the protests of Archelaüs, and giving it out that in the previous battle so many myriads had not perished without treachery. Sulla, however, turning swiftly back, showed Dorylaüs that Archelaüs was a man of prudence and best acquainted with the Roman valour, so that after a slight skirmish with Sulla near Tilphossium, he was first of those who thought it expedient not to decide the issue by a battle, but rather to wear out the war by dint of time and treasure. Nevertheless, Archelaüs was much encouraged by the nature of the country about Orchomenus, where they were encamped, since it was most favourable as a battle-field for an army superior in cavalry.
