The south, on the other hand, was still in the main retained under the power of Macedonia by the fortresses of Chalcis and Corinth, which maintained communication with each other through the territory of the Boeotians who were friendly to the Macedonians, and by the Achaean neutrality; and as it was too late to advance into Macedonia this year, Flamininus resolved to direct his land army and fleet in the first place against Corinth and the Achaeans. The fleet, which had again been joined by the Rhodian and Pergamene ships, had hitherto been employed in the capture and pillage of two of the smaller towns in Euboea, Eretria and Carystus; both however, as well as Oreus, were thereafter abandoned, and reoccupied by Philocles the Macedonian commandant of Chalcis. The united fleet proceeded thence to Cenchreae, the eastern port of Corinth, to threaten that strong fortress. On the other side Flamininus advanced into Phocis and occupied the country, in which Elatea alone sustained a somewhat protracted siege: this district, and Anticyra in particular on the Corinthian gulf, were chosen as winter quarters. The Achaeans, who thus saw on the one hand the Roman legions approaching and on the other the Roman fleet already on their own coast, abandoned their morally honourable, but politically untenable, neutrality. After the deputies from the towns most closely attached to Macedonia --Dyme, Megalopolis, and Argos--had left the diet, it resolved to join the coalition against Philip. Cycliades and other leaders of the Macedonian party went into exile; the troops of the Achaeans immediately united with the Roman fleet and hastened to invest Corinth by land, which city--the stronghold of Philip against the Achaeans --had been guaranteed to them on the part of Rome in return for their joining the coalition. Not only, however, did the Macedonian garrison, which was 1300 strong and consisted chiefly of Italian deserters, defend with determination the almost impregnable city, but Philocles also arrived from Chalcis with a division of 1500 men, which not only relieved Corinth but also invaded the territory of the Achaeans and, in concert with the citizens who were favourable to Macedonia, wrested from them Argos. But the recompense of such devotedness was, that the king delivered over the faithful Argives to the reign of terror of Nabis of Sparta. Philip hoped, after the accession of the Achaeans to the Roman coalition, to gain over Nabis who had hitherto been the ally of the Romans; for his chief reason for joining the Roman alliance had been that he was opposed to the Achaeans and since 550 was even at open war with them. But the affairs of Philip were in too desperate a condition for any one to feel satisfaction in joining his side now. Nabis indeed accepted Argos from Philip, but he betrayed the traitor and remained in alliance with Flamininus, who, in his perplexity at being now allied with two powers that were at war with each other, had in
