Platæa (Third Persian Invasion).
Fought B.C. 479, between the Greeks, about 100,000 strong, under Pausanias the Spartan, and 300,000 Persians, with 50,000 Greek auxiliaries, under Mardonius. The Persians fought bravely, but were overborne by the superior discipline and heavier armour of the Greeks, and Mardonius falling, a panic ensued, and they fled to their entrenched camp. This was stormed by the Athenians, and no quarter was given, with the result, it is said, that with the exception of a body of 40,000 which left the field early in the battle, only 3,000 Persians escaped.
