Then they went forward in a body, and by diligent effort learned of his capture, and sent word of it to the cities of the Achaeans. The Achaeans felt that they had suffered a great calamity, and determined to send an embassy and demand Philopoemen from the Messenians, while they themselves prepared an expedition against the city. The Achaeans, then, were thus engaged. But Deinocrates, who feared that delay was the one thing most likely to save Philopoemen, and wished to forestall the efforts of the Achaeans, when night came on and the multitude of Messene had dispersed, opened the prison and sent in a public official with poison, ordering him to give it to Philopoemen and to stand by his side until he had drunk it.
