But the leaders of affairs in Achaia with the new -strategus- Critolaus at their head -strategus- (from May 607 to May 608), as men versed in state affairs and familiar with political arts, merely drew from that fact the inference that the position of Rome with reference to Carthage and Viriathus could not but be very unfavourable, and continued at once to cheat and to affront the Romans.

Caesar was requested to arrange a conference of deputies of the contending parties at Tegea for the settlement of the question.
He did so; but, after Caesar and the Lacedaemonian envoys had waited there long in vain for the Achaeans, Critolaus at last appeared alone and informed them that the general assembly of the Achaeans was solely competent in this matter, and that it could only be settled at the diet or, in other words, in six months.

Caesar thereupon returned to Rome; and the next national assembly of the Achaeans on the proposal of Critolaus formally declared war against Sparta.
Even now Metellus made an attempt amicably to settle the quarrel, and sent envoys to Corinth; but the noisy -ecclesia-, consisting mostly of the populace of that wealthy commercial and manufacturing city, drowned the voice of the Roman envoys and compelled them to leave the platform.
The declaration of Critolaus, that they wished the Romans to be their friends but not their masters, was received with inexpressible delight; and, when the members of the diet wished to interpose, the mob protected the man after its own heart, and applauded the sarcasms as to the high treason of the rich and the need of a military dictatorship as well as the mysterious hints regarding an impending insurrection of countless peoples and kings against Rome.

The spirit animating the movement is shown by the two resolutions, that all clubs should be permanent and all actions for debt should be suspended till the restoration of peace.
The Achaeans thus had war; and they had even actual allies, namely the Thebans and Boeotians and also the Chalcidians.

At the beginning of 608 the Achaeans advanced into Thessaly to reduce to obedience Heraclea near to Oeta, which, in accordance with the decree of the senate, had detached itself from the Achaean league.
