M. Tullius Cicero Pro L. Murena 33

[33] And when two consuls had been sent to that war, with the view of one pursuing Mithridates, and the other protecting Bithynia, the disasters which befell one of them by land and sea greatly increased the power and reputation of the king. But the exploits of Lucius Lucullus were such that it is impossible to mention any war which was more important, or in which greater abilities and valour were displayed. For when the violence of the entire war had broken against the walls of Cyzicus, and as Mithridates thought that he should find that city the door of Asia, and that if that were once broken down and forced, the whole province would be open to him, everything was so managed by Lucullus that the city of our most faithful allies was defended, and all the forces of the king were wasted away by the length of the siege, what more need I say? Do you think that that naval battle at Tenedos, when the enemy's fleet were hastening on with rapid course and under most eager admirals towards Italy, full of hope and courage, was a trifling engagement—an insignificant contest? I will say nothing of battles; I pass over the sieges of towns. Being at length expelled from his kingdom, still his wisdom and his influence were so great that combining his forces with those of the king of Armenia, he reappeared with new armies and new resources of every kind.
  16 And if it wore my business now to speak of the achievements of our army and of our general, I might mention many most important battles. But that is not the present question.
