When Sylla heard this, he came rapidly up to his succour from the right wing, which as yet had not engaged. But Archelaus, guessing the matter by the dust of his troops, turned to the right wing, from whence Sylla came, in hopes to surprise it without a commander. At the same instant, likewise, Taxiles, with his Brazen Shields, assailed Murena, so that a cry coming from both places, and the hills repeating it around, Sylla stood in suspense which way to move. Deciding to resume his own station he sent in aid to Murena four cohorts under Hortensius, and commanding the fifth to follow him, returned hastily to the right wing, which of itself held its ground on equal terms against Archelaus; and, at his appearance, with one bold effort forced them back, and, obtaining the mastery, followed them, flying in disorder to the river and Mount Acontium. Sylla, however, did not forget the danger Murena was in; but hasting thither and finding him victorious also, then joined in the pursuit. Many barbarians were slain in the field, many more were cut in pieces as they were making into the camp. Of all the vast multitude, ten thousand only got safe intoe Chalcis. Sylla writes that there were but fourteen of his soldiers missing, and that two of these returned towards evening;he, therefore, inscribed on the trophies the names of Mars, Victory, and Venus, as having won the day no less by good fortune than by management and force of arms. This trophy of the battle in the plain stands on the place where Archelaus first gave way, near the stream of the Molus; another is erected high on the top of Thurium, where the barbarians were environed, with an inscription in Greek, recording that the glory of the day belonged to Homoloichus and Anaxidamus.
Sylla celebrated his victory at Thebes with spectacles, for which he erected a stage, near Oedipus's well. The judges of the performances were Greeks chosen out of other cities; his hostility to the Thebans being implacable, half of whose territory he took away and consecrated to Apollo and Jupiter, ordering that out of the revenue compensation should be made to the gods for the riches himself had taken from them.
After this, hearing that Flaccus, a man of the contrary faction, had been chosen consul, and was crossing the Ionian Sea with an army, professedly to act against Mithridates, but in reality against himself, he hastened towards Thessaly, designing to meet him, but in his march, when near Melitea, received advices from all parts that the countries behind him were overrun and ravaged by no less a royal army than the former. For Dorylaus, arriving at Chalcis with a large fleet, on board of which he brought over with him eighty thousand of the best appointed and best disciplined soldiers of Mithridates's army, at once invaded Boeotia, and occupied the country in hopes to bring Sylla to a battle, making no account of the dissuasions of Archelaus, but giving it out as to the last fight, that without treachery so many thousand men could never have perished. Sylla, however, facing about expeditiously, made it clear to him that Archelaus was a wise man, and had good skill in the Roman valour;insomuch that he himself, after some small skirmishes with Sylla near Tilphossium, was the first of those who thought it not advisable to put things to the decision of the sword, but rather to wear out the war by expense of time and treasure. The ground, however, near Orchomenus, where they then lay encamped, gave some encouragement to Archelaus, being a battlefield admirably suited for any army superior in cavalry. Of all the plains in Boeotia that are renowned for their beauty and extent, this alone, which commences from the city of Orchomenus, spreads out unbroken and clear of trees to the edge of the fens in which the Melas, rising close under Orchomenus, loses itself, the only Greek river which is a deep and navigable water from the very head, increasing also about the summer solstice like the Nile, and producing plants similar to those that grow there, only small and without fruit. It does not run far before the main stream disappears among the blind and woody marsh-grounds; a small branch, however, joins the Cephisus, about the place where the lake is thought to produce the best flute-reeds.
Now that both armies were posted near each other, Archelaus lay still, but Sylla employed himself in cutting ditches from either side;that if possible, by driving the enemies from the firm and open champaign, he might force them into the fens. They, on the other hand, not enduring this, as soon as their leaders allowed them the word of command, issued out furiously in large bodies; when not only the men at work were dispersed, but most part of those who stood in arms to protect the work fled in disorder. Upon this, Sylla leaped from his horse, and snatching hold of an ensign, rushed through the midst of the rout upon the enemy, crying out aloud, "To me, O Romans, it will be glorious to fall here. As for you, when they ask you where you betrayed your general, remember and say, at Orchomenus." His men rallying again at these words, and two cohorts coming to his succour from the right wing, he led them to the charge and turned the day.
