he other hand the occupation of Demetrias was successful, for the
Magnetes to whom the city had been assigned were, not without reason,
apprehensive that it had been promised by the Romans to Philip as a
prize in return for his aid against Antiochus; several squadrons of
Aetolian horse moreover managed to steal into the town under the
pretext of forming an escort for Eurylochus, the recalled head of the
opposition to Rome. Thus the Magnetes passed over, partly of their
own accord, partly by compulsion, to the side of the Aetolians, and
the latter did not fail to make use of the fact at the court of the
Seleucid.

Rupture between Antiochus and the Romans

Antiochus took his resolution. A rupture with Rome, in spite of
endeavours to postpone it by the diplomatic palliative of embassies,
could no longer be avoided. As early as the spring of 561 Flamininus,
who continued to have the decisive voice in the senate as to eastern
affairs, had expressed the Roman ultimatum to the envoys of the king,
Menippus and Hegesianax; viz. that he should either evacuate Europe
and dispose of Asia at his pleasure, or retain Thrace and submit to
the Roman protectorate over Smyrna, Lampsacus, and Alexandria Troas.
These demands had been again discussed at Ephesus, the chief place of
arms and fixed quarters of the king in Asia Minor, in the spring of
562, between Antiochus and the envoys of the senate, Publius Sulpicius
and Publius Villius; and they had separated with the conviction on
both sides thata peaceful settlement was no longer possible.
Thenceforth war was resolved on in Rome. In that very summer of 562
a Roman fleet of 30 sail, with 3000 soldiers on board, under Aulus
Atilius Serranus, appeared off Gythium, where their arrival
accelerated the conclusion of the treaty between the Achaeans
and Spartans; the eastern coasts of Sicily and Italy were strongly
garrisoned, so as to be secure against any attempts at a landing; a
land army was expected in Greece in the autumn. Since the spring of
562 Flamininus, by direction of the senate, had journeyed through
Greece to thwart the intrigues of the opposite party, and to
counteract as far as possible the evil effects of the ill-timed
evacuation of the country. The Aetolians had already gone so far as
formally to declare war in their diet against Rome. But Flamininus
succeeded In saving Chalcis for the Romans by throwing into it a
garrison of 500 Achaeans and 500 Pergamenes. He made an
