On August 26, 1922, the Army of the Grand National Assembly ("Büyük Millet Meclisi Ordusu") launched the general offensive known as the Great Offensive ("Büyük Taarruz") against the Greek forces around Kara Hisâr-ı Sâhip. Nurettin Pasha's 1st Army and Yakup Şevki Pasha's 2nd Army encircled the main body of Major General Nikolaos Trikoupis's group and defeated it near Dumlupınar. Fahrettin Pasha's V Cavalry Corps entered Smyrna (Izmir) on September 9, 1922. Şükrü Naili Pasha's III Corps entered Constantinople (Istanbul) peacefully on October 6, 1923. Subsequently to the founding of the Republic of Turkey, the Army of the GNA was reorganized into three army inspectorates ("ordu müfettişliği", 1st, 2nd and 3rd army inspectorate).
