The Greek league had risked the best of its forces in this rash undertaking, and had failed in its enterprise. It had cost the allies so dearly in men and galleys, that if the Persians had at once assumed the offensive, most of the Asiatic cities would have found themselves in a most critical situation; and Athens, then launched in a quarrel with the states of the Peloponnesus, would have experienced the greatest difficulty in succouring them. The feebleness of Artaxerxes, however, and possibly the intrigues at court and troubles in various other parts of the empire, prevented the satraps from pursuing their advantage, and when at length they meditated taking action, the opportunity had gone by. They nevertheless attempted to regain the ascendency over Cyprus; Artabazos with a Sidonian fleet cruised about the island, Megabyzos assembled troops in Cilicia, and the petty kings of Greek origin raised a cry of alarm. Athens, which had just concluded a truce with the Peloponnesians, at once sent two hundred vessels to their assistance under the command of Oimon (449). Cimon acted as though he were about to reopen the campaign in Egypt and despatched sixty of his triremes to King Amyrtceus, while he himself took Marion and blockaded Kition with the rest of his forces. The siege dragged on; he was perhaps about to abandon it, when he took to his bed and died. Those who succeeded him in the command were obliged to raise the blockade for want of provisions, but as they returned and were passing Salamis, they fell in with the Phoenician vessels which had just been landing the Cilician troops, and defeated them; they then disembarked, and, as at Mycale and Eurymedon, they gained a second victory in the open field, after which they joined the squadron which had been sent to Egypt, and sailed for Athens with the dead body of their chief. They had once more averted the danger of an attack on the AEgean, but that was all. The Athenian statesmen had for some time past realised that it was impossible for them to sustain a double conflict, and fight the battles of Greece against the common enemy, while half of the cities whose safety was secured by their heroic devotion were harassing them on the continent, but the influence of Cimon had up till now encouraged them to persist; on the death of Cimon, they gave up the attempt, and Callias, one of their leaders, repaired in state to Susa for the purpose of opening negotiations. The peace which was concluded on the occasion of this embassy might at first sight appear advantageous to their side. The Persian king, without actually admitting his reverses, accepted their immediate consequences. He recognised the independence of the Asiatic Creeks, of those at least who belonged to the league of Delos, and he promised that his armies on land should never advance further than three days' march from the AEgean littoral. On the seas, he forbade his squadrons to enter Hellenic waters
