Battle of Mantinea
In 423 BCE, Laches successfully moved for an armistice with Sparta in the Athenian Assembly. It only lasted a year, but after Cleon died in 422 BCE, Laches, together with Nicias, was able to negotiate the Peace of Nicias. In 418 BCE the peace broke down because of Athens’s support for Spartan rebels. Laches was again appointed general and was killed in the Athenian defeat at the Battle of Mantinea.
