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. But now it was inevitable. They might have acquiesced in the Macedonian state as a neighbour, such as it stood in 549; but it was impossible that they could permit it to acquire the best part of Asiatic Greece and the important Cyrene, to crush the neutral commercial states, and thereby to double its power. Further, the fall of Egypt and the humiliation, perhaps the subjugation, of Rhodes would have inflicted deep wounds on the trade of Sicily and Italy; and could Rome remain a quiet spectator, while Italian commerce with the east was made dependent on the two great continental powers? Rome had, moreover, an obligation of honour to fulfil towards Attalus her faithful ally since the first Macedonian war, and had to prevent Philip, who had already besieged him in his capital, from expelling him from his dominions. Lastly, the claim of Rome to extend her protecting arm over all the Hellenes was by no means an empty phrase: the citizens of Neapolis, Rhegium, Massilia, and Emporiae could testify that that protection was meant in earnest, and there is no question at all that at this time the Romans stood in a closer relation to the Greeks than any other nation - one little more remote than that of the Hellenized Macedonians. It is strange that any should dispute the right of the Romans to feel their human, as well as their Hellenic, sympathies revolted at the outrageous treatment of the Cians and Thasians.

Thus in reality all political, commercial, and moral motives concurred in inducing Rome to undertake the second war against Philip - one of the most righteous, which the city ever waged. It greatly redounds to the honour of the senate, that it immediately resolved on its course and did not allow itself to be deterred from making the necessary preparations either by the exhaustion of the state or by the unpopularity of such a declaration of war. The propraetor Marcus Valerius Laevinus made his appearance as early as 553 with the Sicilian fleet of 38 sail in the eastern waters. The government, however, were at a loss to discover an ostensible pretext for the war; a pretext which they needed in order to satisfy the people, even although they had not been far too sagacious to undervalue, as was the manner of Philip, the importance of assigning a legitimate ground for hostilities. The support, which Philip was alleged to have granted to the Carthaginians after the peace with Rome, manifestly could not be proved. The Roman subjects, indeed, in the province of Illyria had for a considerable time complained of the Macedonian encroachments. In 551 a Roman envoy at the head of the Illyrian levy had driven Philip's troops from the Illyrian territory; and the senate had accordingly declared to the king's envoys in 552, that if he sought war, he would find it sooner than was agreeable to him. But these encroachments were simply the ordinary outrages which Philip practised towards his neighbours; a negotiation regarding them at the present moment would have led to his humbling himself and offering satisfaction, but not to war. With all the belligerent powers in the east the Roman community was nominally in friendly relations, and might have granted them aid in repelling Philip's attack. But Rhodes and Pergamus, which naturally did not fail to request Roman aid, were formally the aggressors; and although Alexandrian ambassadors besought the Roman senate to undertake the guardianship of the boy king, Egypt appears to have been by no means eager to invoke the direct intervention of the Romans, which would put an end to her difficulties for the moment, but would at the same time open up the eastern sea to the great western power. Aid to Egypt, moreover, must have been in the first instance rendered in Syria, and would have entangled Rome simultaneously in a war with Asia and with Macedonia; which the Romans were naturally the more desirous to avoid, as they were firmly resolved not to intermeddle at least in Asiatic affairs. No course was left but to despatch in the meantime an embassy to the east for the purpose, first, of obtaining - what was not in the circumstances difficult - the sanction of Egypt to the interference of the Romans in the affairs of Greece; secondly, of pacifying king Antiochus by abandoning Syria to him; and, lastly, of accelerating as much as possible a breach with Philip and promoting a coalition of the minor Graeco-Asiatic states against him (end of 553). At Alexandria they had no difficulty in accomplishing their object; the court had no choice, and was obliged gratefully to receive Marcus Aemilius Lepidus, whom the senate had despatched as "guardian of the king" to uphold his interests, so far as that could be done without an actual intervention. Antiochus did not break off his alliance with Philip, nor did he give to the Romans the definite explanations which they desired; in other respects, however - whether from remissness, or influenced by the declarations of the Romans that they did not wish to interfere in Syria - he pursued his schemes in that direction and left things in Greece and Asia Minor to take their course.

Meanwhile, the spring of 554 had arrived, and the war had recommenced. Philip first threw himself once more upon Thrace, where he occupied all the places on the coast, in particular Maronea, Aenus, Elaeus, and Sestus; he wished to have his European possessions secured against the risk of a Roman landing. He then attacked Abydus on the Asiatic coast, the acquisition of which could not but be an object of importance to him, for the possession of Sestus and Abydus would bring him into closer connection with his ally Antiochus, and he would no longer need to be apprehensive lest the fleet of the allies might intercept him in crossing to or from Asia Minor. That fleet commanded the Aegean Sea after the withdrawal of the weaker Macedonian squadron: Philip confined his operations by sea to maintaining garrisons on three of the Cyclades, Andros, Cythnos, and Paros, and fitting out privateers. The Rhodians proceeded to Chios, and thence to Tenedos, where Attalus, who had passed the winter at Aegina and had spent his time in listening to the declamations of the Athenians, joined them with his squadron. The allies might probably have arrived in time to help the Abydenes, who heroically defended themselves; but they stirred not, and so at length the city surrendered, after almost all who were capable of bearing arms had fallen in the struggle before the walls. After the capitulation a large portion of the inhabitants fell by their own hand - the mercy of the victor consisted in allowing the Abydenes a term of three days to die voluntarily. Here, in the camp before Abydus. the Roman embassy, which after the termination of its business in Syria and Egypt had visited and dealt with the minor Greek states, met with the king, and submitted the proposals which it had been charged to make by the senate, viz. that the king should wage no aggressive war against any Greek state, should restore the possessions which he had wrested from Ptolemy, and should consent to an arbitration regarding the injury inflicted on the Pergamenes and Rhodians. The object of the senate, which sought to provoke the king to a formal declaration of war, was not gained; the Roman ambassador, Marcus Aemilius Lepidus, obtained from the king nothing but the polite reply that he would excuse what the envoy had said because he was young, handsome, and a Roman.
