XIV. First of all the people of Mantinea made overtures to him. They admitted him to their city by night, aided him to drive out the Achæan garrison, and placed themselves unreservedly in his hands. He, however, restored them to the enjoyment of their own laws and original constitution, and marched away the same day to Tegea. Shortly afterwards by a circuitous march through Arcadia he arrived before the Achæan city of Pheræ, desiring either to fight a battle with the Achæans, or to make Aratus incur the disgrace of retreating and leaving him in possession of the country: for although Hyperbates was nominally in command, all real power over the Achæans was in the hands of Aratus. The Achæans took the field with their entire force, and encamped at Dymæ, near the temple called Hekatombæon. When Kleomenes arrived here he was unwilling to establish himself between the hostile city of Dymæ and the army of the Achæans, and challenged them, forced them to fight, and completely routed their phalanx. He killed many, took a large number of prisoners, and then, marching to Langon, drove out the Achæan garrison, and restored the city to the Eleans. XV. As the Achæan power was now quite broken, Aratus, who was usually elected general every other year, refused to take office, and excused himself when they besought him to do so: a dishonourable act, when the times became more stormy, to desert the helm, and give up his power to another. Kleomenes at first used very moderate language to the Achæan ambassadors, but sent others ordering them to acknowledge him for their sovereign, and promising that if they did so he would do them no further hurt, and would at once restore the prisoners and fortresses which he had taken. As the Achæans were willing to accept these terms they invited Kleomenes to a conference at Lerna. It happened, however, that Kleomenes, after a long march, drank a quantity of cold water, which caused him to bring up much blood, and to lose his voice. In consequence of this, although he sent back the most distinguished of his prisoners, he was obliged to postpone the conference, and went home to Lacedæmon.
