Lampsacus had already fallen, and Thasos had been treated like Cius; no time was to be lost. Theophiliscus, the vigilant -strategus- of Rhodes, exhorted his citizens to meet the common danger by common resistance, and not to suffer the towns and islands to become one by one a prey to the enemy. Rhodes resolved on its course, and declared war against Philip. Byzantium joined it; as did also the aged Attalus king of Pergamus, personally and politically the enemy of Philip. While the fleet of the allies was mustering on the Aeolian coast, Philip directed a portion of his fleet to take Chios and Samos. With the other portion he appeared in person before Pergamus, which however he invested in vain; he had to content himself with traversing the level country and leaving the traces of Macedonian valour on the temples which he destroyed far and wide. Suddenly he departed and re-embarked, to unite with his squadron which was at Samos. But the Rhodo-Pergamene fleet followed him, and forced him to accept battle in the straits of Chios. The number of the Macedonian decked vessels was smaller, but the multitude of their open boats made up for this inequality, and the soldiers of Philip fought with great courage. But he was at length defeated. Almost half of his decked vessels, 24 sail, were sunk or taken; 6000 Macedonian sailors and 3000 soldiers perished, amongst whom was the admiral Democrates; 2000 were taken prisoners. The victory cost the allies no more than 800 men and six vessels. But, of the leaders of the allies, Attalus had been cut off from his fleet and compelled to let his own vessel run aground at Erythrae; and Theophiliscus of Rhodes, whose public spirit had decided the question of war and whose valour had decided the battle, died on the day after it of his wounds. Thus while the fleet of Attalus went home and the Rhodian fleet remained temporarily at Chios, Philip, who falsely ascribed the victory to himself, was able to continue his voyage and to turn towards Samos, in order to occupy the Carian towns. On the Carian coast the Rhodians, not on this occasion supported by Attalus, gave battle for the second time to the Macedonian fleet under Heraclides, near the little island of Lade in front of the port of Miletus. The victory, claimed again by both sides, appears to have been this time gained by the Macedonians; for while the Rhodians retreated to Myndus and thence to Cos, the Macedonians occupied Miletus, and a squadron under Dicaearchus the Aetolian occupied the Cyclades. Philip meanwhile prosecuted the conquest of the Rhodian possessions on the Carian mainland, and of the Greek cities: had he been disposed to attack Ptolemy in person, and had he not preferred to confine himself to the acquisition of his own share in the spoil, he would now have been able to think even of an expedition to Egypt. In Caria no army confronted the Macedonians, and Philip traversed without hindrance the country from Magnesia to Mylasa; but every town in that country was a fortress, and the siege-warfare was protracted without yielding or promising any considerable results. Zeuxis the satrap of Lydia supported the ally of his master with the same lukewarmness as Philip had manifested in promoting the interests of the Syrian king, and the Greek cities gave their support only under the pressure of fear or force. The provisioning of the army became daily more difficult; Philip was obliged today to plunder those who but yesterday had voluntarily supplied his wants, and then he had reluctantly to submit to beg afresh. Thus the good season of the year gradually drew to an end, and in the interval the Rhodians had reinforced their fleet and had also been rejoined by that of Attalus, so that they were decidedly superior at sea. It seemed almost as if they might cut off the retreat of the king and compel him to take up winter quarters in Caria, while the state of affairs at home, particularly the threatened intervention of the Aetolians and Romans, urgently demanded his return. Philip saw the danger; he left garrisons amounting together to 3000 men, partly in Myrina to keep Pergamus in check, partly in the petty towns round Mylasa--Iassus, Bargylia, Euromus and Pedasa --to secure for him the excellent harbour and a landing place in Caria; and, owing to the negligence with which the allies guarded the sea, he succeeded in safely reaching the Thracian coast with his fleet and arriving at home before the winter of 553-4.
Diplomatic Intervention Of Rome
In fact a storm was gathering against Philip in the west, which did not permit him to continue the plundering of defenceless Egypt. The Romans, who had at length in this year concluded peace on their own terms with Carthage, began to give serious attention to these complications in the east. It has often been affirmed, that after the conquest of the west they forthwith proceeded to the subjugation of the east; a serious consideration will lead to a juster judgment. It is only dull prejudice which fails to see that Rome at this period by no means grasped at the sovereignty of the Mediterranean states, but, on the contrary, desired nothing further than to have neighbours that should not be dangerous in Africa and in Greece; and Macedonia was not really dangerous to Rome. Its power certainly was far from small, and it is evident that the Roman senate only consented with reluctance to the peace of 548-9, which left it in all its integrity; but how little any serious apprehensions of Macedonia were or could be entertained in Rome, is best shown by the small number of troops--who yet were never compelled to fight against a superior force--with which Rome carried on the next war. The senate doubtless would have gladly seen Macedonia humbled; but that humiliation would be too dearly purchased at the cost of a land war carried on in Macedonia with Roman troops; and accordingly, after the withdrawal of the Aetolians, the senate voluntarily concluded peace at once on the basis of the -status quo-. It is therefore far from made out, that the Roman government concluded this peace with the definite design of beginning the war at a more convenient season; and it is very certain that, at the moment, from the thorough exhaustion of the state and the extreme unwillingness of the citizens to enter into a second transmarine struggle, the Macedonian war was in a high degree unwelcome to the Romans.
