(Greek: Παγώνδας) son of Aeolidas, was a Theban general and statesman, who is best known for his command of the Boeotian forces at the Battle of Delium during the Peloponnesian War. His modification of the standard hoplite formation and his use of reserve cavalry in that battle constitute what most historians agree is the first recorded use of formal military tactics in human history.
