at the
Battle of Plataea in 479 BC. In 479 BC, Pausanias was leader of the Spartan army alongside
Euryanax, son of
Dorieus, as the Agiad king of Sparta
Pleistarchus, son of
Leonidas I, was too young to command. Pausanias led 5000 Spartans to the aid of the league of Greek cities created to resist the Persian invasion. At the Greek encampment at Plataea 110,000 men were assembled along the
Asopos River. Further down the river,
Mardonius, commander of the Persian forces, stationed 300,000 Persian forces alongside 50,000 Greek allies. After eleven days of stalemate, Mardonius offered a challenge that was ignored by the Greeks. With no answer to his challenge, Mardonius ordered his cavalry to pollute the
Asopos from which the Greeks were getting their water, so the Athenian forces decided in the night to move towards
Plataea. The forces led by Pausanias headed through the ridges and foothills of the
Cithaeron while the Athenian forces headed the opposite direction onto the plains. Seeing this, Mardonius thought the Athenians were fleeing, so he sent his Persian forces to charge Pausanias' army while dispatching his Greek allies to go after the Athenians. With the battle underway Pausanias sent a messenger to ask for Athenian aid, but they could not spare any. So Pausanias with 50,000
Lacedaemonians and 3,000
Tegeans prepared for battle at Plataea. In the subsequent
Battle of Plataea, Pausanias led the Greeks to a major victory over the Persians and their allies. While the Battle of Plataea is sometimes seen as a chaotic battle, others see evidence of both Pausanias' strategic and tactical skills in delaying the engagement with the Persians until the point where Spartan arms and discipline could have maximum impact.
Herodotus concluded that "Pausanias the son of Cleombrotus and grandson of
Anaxandridas won the most glorious victory of any known to us". After the victories at Plataea and the subsequent
Battle of Mycale, the Spartans lost interest in liberating the Greek cities of
Asia Minor until it became clear that
Athens would dominate the League in Sparta's absence. Sparta then sent Pausanias back to command the Greek military. ==Suspected pact with Persia==
