Nicias

On October 10, 413 BC, Nicias, Athens politician and general who made the Peace of Nicias with Sparta, was executed by the Syracusans at about the age of 57. An excerpt from the article:

"Nicias, or Nikias (c. 470-413 BCE), was a wealthy Athenian politician and general during the Peloponnesian War (431-404 BCE). He became established as a prominent political leader of the aristocratic faction in Athenian politics and generally recommended a cautious line in opposition to the more hawkish anti-Spartan attitudes of popular leaders such as Cleon and Alcibiades. After the death of Cleon (422 BCE), he negotiated the Peace of Nicias with Sparta, temporarily ending the Peloponnesian War. As a general he was known for his prudence, and he argued against launching the Sicilian Expedition. Nonetheless, he still joined the campaign when chosen as one of its generals. Despite the high risks involved, the campaign came close to success; however, when the tide turned against Athens, Nicias' indecision hindered the Athenian escape. Captured by the Syracusans, Nicias and his fellow general Demosthenes were executed."
