These operations against the inland neighbors of Macedonia must have occupied a year or two. During that interval, Philip left Amphipolis to itself, having withdrawn from it the Macedonian garrison as a means of conciliating the Athenians. We might have expected that they would forthwith have availed themselves of the opening and taken active measures for regaining Amphipolis. They knew the value of that city: they considered it as of right theirs; they had long been anxious for its repossession, and had even besieged it five years before, though seemingly only with a mercenary force, which was repelled mainly by the aid of Philip’s predecessor Perdikkas. Amphipolis was not likely to surrender to them voluntarily; but when thrown upon its own resources, it might perhaps have been assailed with success. Yet they remained without making any attempt on the region at the mouth of the river Strymon. We must recollect (as has been narrated in my last preceding volume[450]), that during 359 B. C., and the first part of 358 B. C., they were carrying on operations in the Thracian Chersonese, against Charidemus and Kersobleptes, with small success and disgraceful embarrassment. These vexatious operations in the Chersonese—in which peninsula many Athenians were interested as private proprietors, besides the public claims of the city—may perhaps have absorbed wholly the attention of Athens, so as to induce her to postpone the acquisition of Amphipolis until they were concluded; a conclusion which did not arrive (as we shall presently see) until immediately before she became plunged in the dangerous crisis of the Social War. I know no better explanation of the singular circumstance, that Athens, though so anxious, both before and after, for the possession of Amphipolis, made no attempt to acquire it during more than a year after its evacuation by Philip; unless indeed we are to rank this opportunity among the many which she lost (according to Demosthenes[451]) from pure negligence; little suspecting how speedily such opportunity would disappear.
