(25) The illustrative incidents narrated in chapter iv. 17 may belong to this period. VI B.C. 390-389. (1) At a later date the Achaeans, being in possession of Calydon, a town from old times belonging to Aetolia, and having further incorporated the Calydonians as citizens, (2) were under the necessity of garrisoning their new possession. The reason was, that the Arcarnanians were threatening the place with an army, and were aided by contingents from Athens and Boeotia, who were anxious to help their allies. (3) Under the strain of this combined attack the Achaeans despatched ambassadors to Lacedaemon, who on arrival complained of the unfair conduct of Lacedaemon towards themselves. "We, sirs," they said, "are ever ready to serve in your armies, in obedience to whatever orders you choose to issue; we follow you whithersoever you think fit to lead; but when it comes to our being beleaguered by the Acarnanians, with their allies the Athenians and Boeotians, you show not the slightest concern. Understand, then, that if things go on thus we cannot hold out; but either we must give up all part in the war in Peloponnesus and cross over in full force to engage the Arcarnanians, or we must make peace with them on whatever terms we can." This language was a tacit threat that if they failed to obtain the assistance they felt entitled to from Lacedaemon they would quit the alliance. (1) According to others (who suppose that the Isthmia and the events recorded in chapter v. 1-19 above belong to B.C. 392), we have now reached B.C. 391. (2) Or, "having conferred a city organisation on the Calydonians." (3) See Thuc. ii. 68.
