Regular army: 9,167 killed 2,474 died of wounds or non-combat causes 31,097 wounded 11,150 missing 6,522 prisoners**	19,362 killed 4,878 died outside of combat 48,880 wounded 18,095 missing ~13,740 prisoners*
according to Turkish sources 20,826 Greek prisoners were taken. Of those about 740 officers and 13,000 soldiers arrived in Greece during the prisoner exchange in 1923. The rest presumably died in captivity and are listed among the "missing". **Greece took 22,071 military and civilian prisoners. Of those were 520 officers and 6,002 soldiers. During the prisoner exchange in 1923, 329 officers, 6,002 soldiers and 9,410 civilian prisoners arrived in Turkey. The remaining 6,330, mostly civilian prisoners, presumably died in Greek captivity. The Turkish Grand National Assembly was opened in 1920. Kuva-yi Milliye operated independently between 1919–20 until it was put under the control of the Grand National Assembly.

The Greco-Turkish War of 1919–1922, known as the Western Front (Turkish: Batı Cephesi, Ottoman Turkish: Garb Cebhesi گرب جابهاسی‎) of the Turkish War of Independence in Turkey and the Asia Minor Campaign (Greek: Μικρασιατική Εκστρατεία) or the Asia Minor Catastrophe (Greek: Μικρασιατική Καταστροφή) in Greece, was fought between Greece and the Turkish National Movement during the partitioning of the Ottoman Empire after World War I between May 1919 and October 1922.

The Greek campaign was launched primarily because the western Allies, particularly British Prime Minister David Lloyd George, had promised Greece territorial gains at the expense of the Ottoman Empire, recently defeated in World War I. The armed conflict started when the Greek forces landed in Smyrna (now Izmir), on 15 May 1919. They advanced inland and took control of the western and northwestern part of Anatolia, including the cities of Manisa, Balıkesir, Aydın, Kütahya, Bursa and Eskişehir. Their advance was checked at the Battle of Sakarya in 1921 by forces of the Turkish national movement. The Greek front collapsed with the Turkish counter-attack in August 1922, and the war effectively ended with the capture of Smyrna by the Turkish forces and the Great Fire of Smyrna.
