Third, he taunted the Athenian generals over their failure to bring the war in Sphacteria to a rapid close, accusing them of cowardice, and declared that he could finish the job himself in twenty days, despite having no military knowledge. They gave him the job, expecting him to fail. Cleon shrank at being called to make good on his boast, and tried to get out of it, but he was forced to take the command. In fact, he succeeded—by getting the general Demosthenes to do it, now treating him with respect after previously slandering him behind his back. Three years later, Cleon and his Spartan counterpart Brasidas were killed at the Battle of Amphipolis, enabling a restoration of peace that lasted until the outbreak of the Second Peloponnesian War.
