Then, re-enforced by forty galleys from Athens, and twenty-five from Lesbos and Chios, he landed on the island, defeated the Samians in a pitched battle, drove them into their city, invested it with a triple line of ramparts, and simultaneously blockaded the city by sea. The besieged were not, however, too discouraged to sally out; and, under Melissus, who was at once a philosopher and a hero, they even obtained advantage in a seafight. But these efforts were sufficiently unimportant to permit Pericles to draw off sixty of his vessels, and steer along the Carian coast to meet the expected fleet of the Phoenicians. The besieged did not suffer the opportunity thus afforded them to escape--they surprised the naval blockading force, destroyed the guard-ships, and joining battle with the rest of the fleet, obtained a decisive victory (B. C. 440), which for fourteen days left them the mastery of the open sea, and enabled them to introduce supplies. IV. While lying in wait for the Phoenician squadron, which did not, however, make its appearance, tidings of the Samian success were brought to Pericles. He hastened back and renewed the blockade--fresh forces were sent to his aid--from Athens, forty-eight ships, under three generals, Thucydides [312], Agnon, and Phormio; followed by twenty more under Tlepolemus and Anticles, while Chios and Lesbos supplied an additional squadron of thirty. Still the besieged were not disheartened; they ventured another engagement, which was but an ineffectual struggle, and then, shut up within their city, stood a siege of nine months.
