Then, when the wind served, he suddenly launched his ships and put out to sea, and by sailing in the day time with his sails reefed and low, but in the night time under full canvas, he came safely to Rhodes. The Rhodians furnished him with more ships, and he induced the people of Cos and Cnidus to forsake the royal cause and join him in an expedition against Samos. Without any aid he also drove the royal forces out of Chios, 85 B.C. and set the Colophonians free from their tyrant, Epigonus, whom he arrested. It happened about this time that Mithridates abandoned Pergamum and shut himself up in Pitané. Since Fimbria held him in close siege there by land, he looked to make his escape by sea, and collected and summoned his fleets from every quarter for this purpose, renouncing all engagements in the field with a man so bold and victorious as Fimbria.
