When they joined battle with the Hellenes, they fared neither better nor worse than the Median army, since they used shorter spears than the Hellenes and could not use their numbers fighting in a narrow space.

The Lacedaemonians fought memorably, showing themselves skilled fighters amidst unskilled on many occasions, as when they would turn their backs and feign flight. The barbarians would see them fleeing and give chase with shouting and noise, but when the Lacedaemonians were overtaken, they would turn to face the barbarians and overthrow innumerable Persians. A few of the Spartans themselves were also slain. When the Persians could gain no inch of the pass, attacking by companies and in every other fashion, they withdrew.
