Agis and Cleomenes

And so Cleomenes, finding Xenares averse, and thinking that everybody else was of like mind with him, began to arrange his project all by himself. And because he thought that he could better bring about his reforms in time of war than in the midst of peace, he embroiled the state with the Achaeans, who were themselves giving grounds for complaint. For Aratus, the most powerful man among the Achaeans, was from the outset desirous of bringing all the Peloponnesians into one confederation, and this was the end pursued by him during his many generalships and his long political activity,

since he was of the opinion that in this way alone would they be safe from the attacks of their enemies without. Nearly all the other Peloponnesians adopted his views, but the Lacedaemonians, the Eleians, and the Arcadians who sided with the Lacedaemonians held aloof. Therefore, as soon as Leonidas was dead, Aratus began to harass the Arcadians, and ravaged the territories of those especially who were adjacent to Achaea. His object was to put the Lacedaemonians to the test, and he despised Cleomenes as a young and inexperienced man.

Upon this, the ephors began operations by sending Cleomenes to occupy the precinct of Athena at Belbina. This commands an entrance into Laconia, and was at that time a subject of litigation with the Megalopolitans. After Cleomenes had occupied and fortified this place, Aratus made no public protest, but led out his forces one night and tried to surprise Tegea and Orchomenus.
