Leocrates, son of Stroebus, was a leading Athenian general of the First Peloponnesian War. He led the Athenian forces that conquered the island of Aegina, traditionally a naval rival of Athens. In 458 BC Leocrates led a large Athenian fleet that engaged the Aeginetan fleet in the Saronic Gulf near Aegina. After a major sea-battle in which reportedly the Athenians captured or sunk seventy ships, Leocrates led the Athenian forces ashore to besiege Aegina. The Aeginetans eventually surrendered to the Athenians and became subject allies of Athens.
