In either 460 or 459 BC, Athens fought a number of major battles against the combined forces of several Peloponnesian states. On land, the Athenians were defeated by the armies of Corinth and Epidaurus at Halieis, but at sea they were victorious at Cecryphaleia (a small island between Aegina and the coast of Epidaurus). Alarmed by this Athenian aggressiveness in the Saronic Gulf, Aegina entered into the war against Athens, combining its powerful fleet with that of the Peloponnesian allies. In the resulting sea battle, the Athenians won a commanding victory, capturing seventy Aeginetan and Peloponnesian ships. They then landed at Aegina and, led by Leocrates, laid siege to the city.
