Plataea was one of the biggest and most important land battles of pre-20th century history. Close to 100,000 hoplite and light-armed Greeks took on an even larger barbarian army that included elite Asian cavalry and infantry from as far away as India, with thousands of Greek hoplites and cavalry also fighting on the Persian side. At points in the several days of battle, the Persians with their more fluid, missile tactics came close to breaking the Greek defensive line and cutting off their supplies.
