This was the first great victory (in September, 376 B.C.[278]) which the Athenians had gained at sea since the Peloponnesian war; and while it thus filled them with joy and confidence, it led to a material enlargement of their maritime confederacy. The fleet of Chabrias,—of which a squadron was detached under the orders of Phokion, a young Athenian now distinguishing himself for the first time and often hereafter to be mentioned,—sailed victorious round the Ægean, made prize of twenty other triremes in single ships, brought in three thousand prisoners with one hundred and ten talents in money, and annexed seventeen new cities to the confederacy, as sending deputies to the synod and furnishing contributions. The discreet and conciliatory behavior of Phokion, especially obtained much favor among the islanders, and determined several new adhesions to Athens.[279] To the inhabitants of Abdêra in Thrace, Chabrias rendered an inestimable service, by aiding them to repulse a barbarous horde of Triballi, who quitting their abode from famine, had poured upon the sea-coast, defeating the Abderites and plundering their territory. The citizens, grateful for a force left to defend their town, willingly allied themselves with Athens, whose confederacy thus extended itself to the coast of Thrace.[280] [278] Plutarch, Phokion, c. 6; Plutarch, Camillus, c. 19.
