[216-208 B.C.]
A year had elapsed since the alliance had been formed against Achaia, when Philip of Macedon, in the depth of winter, set out with the utmost secrecy to Corinth, where a part of his forces were stationed. He surprised a party of Eleans, who had gone forth to ravage the Sicyonian territories, and reduced Psophis, a stronghold within the confines of Arcadia, of which the Eleans had taken possession. He plundered Elis, one of the finest regions in Greece, in respect to cultivation, and rich in every kind of rural wealth. He next subdued under his power Triphylia, a district of Peloponnesus to the southward of Elis, and wrested the Ætolian yoke from the necks of the Messenians. Philip made a temperate use of all his victories. He granted peace to all who sued for it; and the whole of his conduct seemed to be directed by the same generous motives which had formerly directed that of Antigonus. But in the midst of these fair appearances, Philip began to manifest latent seeds of ambition. He restrained the pride and power of his ministers, who had been appointed to their offices by his predecessor Antigonus; and supported Eperatus in the election of general of Achaia, in opposition to Aratus. In order to counterbalance this unpopular measure, and to strengthen himself in the affections of the Achæan people, he besieged Teichos, and having taken that fortress, restored it to the Achæans, to whom it belonged. He also made an inroad into Elis, and presented the Dymeans and the cities in the neighbourhood with all the plunder. He now imagined that the wealth and vigour of the Achæan republic were at his disposal; but the new general had not provided any magazines, and the treasury was exhausted. Philip now affected to place great confidence in Aratus. By the advice of this statesman, he made an attempt on the island of Cephallenia, an island in the Ionian Sea, near the coast of Peloponnesus, and the great resort of the Ætolian pirates. His attempt, after it had been carried on almost to success, was baffled by the treachery of his ministers.
He now, following the advice of Aratus, invaded and ravaged Ætolia itself, returned into Peloponnesus, laid waste Laconia, and, flushed with success, meditated the subjection of all Greece, and a junction with Hannibal against the Romans. Aratus in vain attempted to dissuade him from this project. He sent ambassadors to the Carthaginian general, but they were intercepted, soon after their landing in Italy: as they gave out, however, that they were going to Rome, they, in a little time, obtained their release, and made their way to Hannibal, with whom they concluded a treaty. On their return they were again intercepted, and sent with all their papers to Rome. But Philip despatched other ambassadors, and a ratification of the treaty was obtained. It was stipulated that Philip should furnish a fleet of two hundred ships, to be employed in harassing the Italian coasts; and that he should also assist Hannibal with a considerable body of land-forces. In return for this assistance, when Rome and Italy should be finally reduced, which were to remain in the possession of the Carthaginians, Hannibal was to pass into Epirus at the head of a Carthaginian army, to be employed as Philip should desire; and, having made a conquest of the whole country, to give up to him such parts of it as lay convenient for Macedon.
In consequence of this agreement, the Macedonian king entered the Ionian Gulf, with a large fleet, fell down to the coast of Epirus, took Oricum, on the coast of Epirus, a defenceless seaport, but from which there was a short passage to Italy, and laid siege to Apollonia; but surprised and defeated by the Romans, secretly retreated homeward across the mountains.
ALLIANCE WITH ROME
The Romans, humbled by the victorious arms of Hannibal, were not in a condition in which they might prosecute a war with Macedon; they therefore determined, if possible, to raise up enemies against Philip in Greece, that he might be employed at home in the defence of his own dominions. They accordingly made overtures for this purpose to the Ætolians, who, confiding in the flattering declarations of the Roman ambassador, hastened to conclude a treaty, of which the following were the principal conditions: That the Ætolians should immediately commence hostilities against Philip by land, which the Romans were to support by a fleet of twenty galleys; that whatever conquests might be made, from the confines of Ætolia to Corcyra, the cities, buildings, and territory, should belong to the Ætolians, but every other kind of plunder to the Romans. The Spartans and Eleans, with other states, were included in this alliance; and the war commenced with the reduction of the island of Zacynthus, which, as an earnest of Roman generosity and good faith, was immediately annexed to the dominions of Ætolia. These transactions were dated about 208 B.C.
[208-205 B.C.]
It has already been observed, that Philip aimed at the subjection of all Greece. Aratus, who would have opposed him in this design, he took off by poison.[51] His interest in Greece was now strengthened by the introduction of the Romans: he was regarded by the Greeks as the champion of freedom, and as their defence against the Romans, whom they still considered and denominated barbarians. Not only the Greeks northward of the Corinthian isthmus, but even the Achæan League, prepared to take up arms in his support. Encouraged by these allies, he acted with uncommon vigour: he carried the war into Illyricum with success; marched to the relief of the Acarnanians, who were threatened by the Ætolians, and fortified himself in Thessaly. The Ætolians, notwithstanding these advantages gained over them by Philip, and that they were afterwards defeated by him in two hot engagements, remained undaunted, and prosecuted the war with an amazing obstinacy. The neighbouring states, now jealous of the successes of Philip, endeavoured to mediate a peace; nor did the Macedonian show himself unwilling to treat for that purpose.
A peace was ready to be concluded, when the Romans, deeply interested in the prolongation of war, sent their fleet to support the Ætolians; who, encouraged also by the prospect of acquiring another ally, Attalus, king of Pergamus, boldly set Philip at defiance, and talked of terms to which they knew he would not submit. The moderation of Philip strengthened the indignation of his Greek confederates against the Ætolians; a disposition which he soon found an opportunity of calling forth into action. Intelligence being brought to him, whilst he was assisting at the Nemean games, that the Romans had landed, and were laying waste the country from Corinth to Sicyon, he instantly set out, attacked and repulsed the enemy, and, before the conclusion of the games, returned again to Argos; an achievement which greatly distinguished him in the eyes of all Greece, assembled at that solemnity. After other vigorous, though unsuccessful, exertions against the Romans, he was called back, by domestic insurrections, to Macedon.
The Achæan states, though deprived of the powerful aid of the Macedonian king, still carried on their military operations under the conduct of Philopœmen of Megalopolis, in Arcadia, an enthusiast in the cause of liberty from his earliest years, and one who had been active in bringing over several of the Arcadians to join the Achæan League. Soon after the death of Aratus, to whom he was as much superior in military, as he was inferior in political abilities, he attained the chief sway in the Achæan councils. He saw with concern the humiliating condition to which a foreign yoke had reduced his countrymen, and conceived the noble resolution of relieving them from it. In the character of general of Achaia, he improved their discipline, inured them to hardship and toil, and gave them weightier armour, and more powerful weapons. The effect of this discipline soon appeared: the armies of Ætolia and Elis, which attacked them in Philip’s absence, were totally defeated. In the meantime, the Romans, supported by Attalus, attacked Eubœa, of all the provinces of Greece, though an island, one of the most considerable for fertility of soil, extent of territory, and advantage of situation. Philip, on his part, kept a watchful eye on his enemies: his military preparations were vigorous, and not without success. The war was prolonged, with various success, for six years, when the Romans and Attalus retired from Greece. A peace was now concluded between the Ætolians and Romans, on the one part, and Philip on the other, whose successful ambition led him, by a natural progress, to attack the dominions of the king of Egypt.
