One of these strategies was shown in the battle between Greek city states and Persia. The Battle of Thermopylae in which the Greek forces were outnumbered stood as a good military strategy. The Greek allied forces ultimately lost the battle, but the training, use of armor, and location allowed them to defeat many Persian troops before losing. In the end, the Greek alliance lost the battle but not the war as a result of that strategy which continued on to the battle of Plataea. The Battle of Plataea in 479 BC resulted in a victory for the Greeks against Persia, which exemplified that military strategy was extremely beneficial to defeating a numerous enemy.
