The Battle of the Gediz was fought between pro-Turkish Kuva-yi Milliye forces and the Greek forces near the Gediz River in the city of Gediz. The Turkish forces attacked Gediz in order to find out if a force composed mainly of irregular forces could compete with the Greek army in a larger battle. Although the battle temporarily stopped the Greek advance towards Ankara, it also showed that the irregular forces lacked discipline and experience; they had no chance in open field battles against the Greeks. The experiences gained in this battle, lead the GNA to the conclusion that it would be necessary from now on to establish and fight with a regular army against the Greek army instead of irregular forces.
