=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. BATTLE OF ARGINUSÆ. A long and obstinate combat followed; but Callicratidas was at length thrown overboard and drowned, and victory declared for the Athenians. The Spartans had lost seventy-seven vessels, and their fleet at Mytilene hastily withdrew, leaving the harbor open for the escape of Conon. [Sidenote: B. C. 405.] =205.= At the beginning of the next year, Lysander was again placed in command of the Spartan fleet. His numbers being still inferior, he avoided an engagement, but he crossed the Ægean to the coast of Attica, for a personal Consultation with Agis, and thence proceeded to the Hellespont, where he commenced the siege of Lampsacus. The Athenian fleet followed, but arrived too late to save the town. Conon stationed himself, however, at Ægos-Potami (Goat’s River), on the northern side of the channel, with the intention of bringing the Spartan to an engagement. The Athenians were upon a barren plain; while the Spartans, better situated and abundantly supplied with provisions, were in no haste to begin the battle. Alcibiades, who was living near in his own castle, saw the danger of his countrymen, and advised their generals to remove to Sestus, but his counsels were resented as impertinence; and attributing the Spartan delay to cowardice, the Athenians became every day more neglectful of discipline.
