The Council of Ministers took the decision to attack and on August 14, 1922, the corps marched for the attack, the attack started on August 26, the Turkish Army entered Izmir on September 9, and on September 18, when the Greek Army left Anatolia completely, the war has ended.
Although the Turkish Army won the Battle of Sakarya, it was not in a position to destroy the Greek armies by forcing them into war. The Turkish army had great deficiencies in order to launch an offensive. The public has been asked to make one last sacrifice to eliminate these. All financial resources were strained to the limit and preparations were started immediately; officers and soldiers began to be trained for the assault. All the resources of the country were placed at the disposal of the military. The troops on the East and South fronts, where the battles actually ended, were also shifted to the West front. On the other hand, the associations that supported the Turkish liberation struggle in Istanbul sent the weapons they smuggled from the Allied Powers' arsenals to Ankara. The Turkish army was to attack for the first time and therefore had to outnumber Greek troops. There were 200.000 Greek soldiers in Anatolia during this period. After a year of preparation, the Turkish army increased the number of soldiers in the army to 186.000 and approached the Greek troops. However, despite all these efforts, the Turkish army could not provide an advantage to the Greek troops, except for the cavalry units, but a balance was achieved.

For this reason, there is no need for the powers of our supreme assembly. He stated that there is no need for extraordinary articles in the law. The Commander-in-Chief law was extended indefinitely with the decision of the parliament. After the Battle of Sakarya, impatience arose in the public and in the Turkish Grand National Assembly for the attack. These developments on Mustafa Kemal Pasha, March 6, 1922 Turkey Grand National Assembly in a secret meeting and those concerned about unrest in the "decision of our army, we're offensive. But we postpone this attack. The reason is that we need a little more time to finish our preparation completely. An attack with half preparation and half measures is much worse than no attack at all. " On the one hand, while trying to eliminate the doubt in their minds, on the other hand, he prepared the army for an attack that would ensure the final victory.
