The Athenians forestalled the attack--made a descent on Haliae, in Argolis--were met by the Corinthians and Epidaurians, and the result of battle was the victory of the latter. This defeat the Athenians speedily retrieved at sea. Off Cecryphalea, in the Saronic gulf, they attacked and utterly routed the Peloponnesian fleet. And now Aegina openly declared war and joined the hostile league. An important battle was fought by these two maritime powers with the confederates of either side. The Athenians were victorious--took seventy ships-- and, pushing the advantage they had obtained, landed in Aegina and besieged her city. Three hundred heavy-armed Peloponnesians were despatched to the relief of Aegina; while the Corinthians invaded the Megarian territory, seized the passes of Geranea, and advanced to Megara with their allies. Never was occasion more propitious. So large a force in Egypt, so large a force at Aegina--how was it possible for the Athenians to march to the aid of Megara? They appeared limited to the choice either to abandon Megara or to raise the siege of Aegina: so reasoned the Peloponnesians. But the advantage of a constitution widely popular is, that the whole community become soldiers in time of need. Myronides, an Athenian of great military genius, not unassisted by Pericles, whose splendid qualities now daily developed themselves, was well adapted to give direction to the enthusiasm of the people. Not a man was called from Aegina. The whole regular force disposed of, there yet remained at Athens those too aged and those too young for the ordinary service. Under Myronides, boys and old men marched at once to the assistance of their Megarian ally. A battle ensued; both sides retiring, neither considered itself defeated. But the Corinthians retreating to Corinth, the Athenians erected a trophy on the field. The Corinthian government received its troops with reproaches, and, after an interval of twelve days, the latter returned to the scene of contest, and asserting their claim to the victory, erected a trophy of their own. During the work the Athenians sallied from Megara, where they had ensconced themselves, attacked and put to flight the Corinthians; and a considerable portion of the enemy turning into ground belonging to a private individual, became entangled in a large pit or ditch, from which was but one outlet, viz., that by which they had entered. At this passage the Athenians stationed their heavy-armed troops, while the light-armed soldiers surrounded the ditch, and with the missiles of darts and stones put the enemy to death. The rest (being the greater part) of the Corinthian forces effected a safe but dishonourable retreat.
