As the siege was not going on favourably for him, and the enemy were blockading him with an increasing number of decked vessels, he felt uncertain and uneasy as to the result. But as the state of affairs left him no choice, he suddenly put to sea quite unexpectedly to the enemy; for Attalus expected that he would persist in pushing on the mines he had commenced. But Philip was especially keen to make his putting to sea a surprise, because he thought that he would thus be able to outstrip the enemy, and complete the rest of his passage along the coast to Samos in security. But he was much disappointed in his calculations; for Attalus and Theophiliscus (of Rhodes), directly they saw him putting to sea, lost no time in taking action. And although, from their previous conviction that Philip meant to stay where he was, they were not in a position to put to sea quite simultaneously, still by a vigorous use of their oars they managed to overtake him, and attacked,—Attalus the enemy’s right wing, which was his leading squadron, and Theophiliscus his left. Thus intercepted and surrounded, Philip gave the signal to the ships of his right wing, ordering them to turn their prows towards the enemy and engage them boldly; while he himself retreated under cover of the smaller islands, which lay in the way, with some light galleys, and thence watched the result of the battle. The whole number of ships engaged were, on Philip’s side, fifty-three decked, accompanied by some undecked vessels, and galleys and beaked ships to the number of one hundred and fifty; for he had not been able to fit out all his ships in Samos. On the side of the enemy there were sixty-five decked vessels, besides those which came from Byzantium, and along with them nine triemioliae (light-decked vessels), and three triremes.
