=201.= The arrival of two new officers upon the Asiatic field of war turned the scale against Athens. The one was Cyrus, a son of the Persian king; the other was Lysander, the new Spartan _navarchus_, who took command of the Peloponnesian fleet at Ephesus. These two made common cause, and together took measures for severe and unrelenting war against the Athenians. The gold which the Persian prince lavished without stint, the Spartan applied to increasing the wages of his seamen. By this well-timed liberality, he drew over great numbers of men from the opposing fleet, and rendered even those who did not desert, discontented and mutinous.
=202.= Alcibiades arrived with his fleet to find the situation less favorable than he had hoped. The Spartan troops were better paid and equipped than his own, and to raise funds he resorted to levying forced contributions on friendly states. During his absence on one of these forays, the fleet became engaged in battle with the Spartans, and was defeated with considerable loss. The Athenians began to perceive that eight years’ exile and two or three years’ good behavior, had not altered the character of the man, but that he was as dissolute, fickle, and unscrupulous as ever. They dismissed him from his command, and appointed ten generals, with Conon at their head.
=203.= At the same time that Conon arrived to take command of the Athenians, Cal´licrat´idas succeeded Lysander as _navarchus_. He found an empty treasury and a cold reception, alike from his own countrymen and the Persians, whom Lysander had purposely prejudiced against him. Cyrus refused to see or aid him. Callicratidas now took bolder counsel. He sailed to Miletus, and urged its citizens to throw off the Persian alliance. Many rich men came forward with generous contributions of money, with which he equipped fifty new triremes, and sailed to Lesbos with a fleet twice as numerous as that of the Athenians.
=204.= He had a battle with Conon in the harbor of Mytilene, in which the Athenians lost nearly half their ships, and only saved the rest by drawing them ashore under the walls of the town. Callicratidas then blockaded the city by sea and land; and Cyrus, perceiving his success, assisted him with supplies of money. Great efforts were made at Athens, as soon as the condition of Conon was known. A large fleet was sent out in a few days, and being reinforced by the allies at Samos, arrived at the south-eastern extremity of Lesbos, numbering 150 vessels. Callicratidas left fifty ships to continue the blockade, and sailed to meet his enemy.
