One of the fronts in the War of Independence is the Western Front. Against the Greek invasion that started in Izmir on 15 May 1919, Kuva-yı Milliye units were formed on this front and the resistance was initiated. However, the negativities of these unions were also seen. It was decided to establish a regular army in order to win a decisive victory over the Greek army. Mustafa Kemal Pasha assigned Ali Fuat Pasha, the commander of Umum Kuva-yı Milliye, to the Moscow Embassy. It divided the Western Front into two. He appointed Colonel İsmet Bey to the western part of the front and Colonel Refet Bey to the southern part. Thus, the regular army was introduced. The troops of Kuva-yı Milliye also joined the regular army. However, there were some problems during this operation. Ethem and his forces did not want to join the regular army. They cooperated with the Greek army. Despite this, the First Battle of İnönü was won. At the invitation of the Entente States, both the Istanbul Government and the Ankara Government representatives attended the London Conference. When the conference failed, the Greek army attacked again. At the end of the heroic struggle of the Turkish army, the Second Battle of İnönü was won. The Greek army had to retreat once again. Mustafa Kemal Pasha was delighted with these victories on the Western Front. In this study, it is focused on the statements, thoughts and comments of Mustafa Kemal Pasha about the Battles of İnönü.
