To stop this invasion the Greeks held counsel and resolved to send a Greek force to Theropylae. This force consisted of 4,200 Greeks and 300 Spartans, and at its head was Leonidas.Thermopylae was a very narrow passage being only 50 feet wide. On one side there is a steep cliff face, on the other was a straight drop into the ocean. This was an ideal place for the Greeks to fight for it would make their phalanx more effective, and nullify the Persian's superior numbers.
