The Greco-Turkish War of 1919–1922 was fought between Greece and the Turkish National Movement during the partitioning of the Ottoman Empire in the aftermath of 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. Greek claims stemmed from the fact that Anatolia had been part of Ancient Greece and the Byzantine Empire before the Turks conquered the area in the 12th-15th centuries. The armed conflict started when the Greek forces landed in Smyrna (now İzmir), 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 by Turkish forces at the Battle of the Sakarya in 1921. The Greek front collapsed with the Turkish counter-attack in August 1922, and the war effectively ended with the recapture of Smyrna by Turkish forces and the great fire of Smyrna.

As a result, the Greek government accepted the demands of the Turkish National Movement and returned to its pre-war borders, thus leaving Eastern Thrace and Western Anatolia to Turkey. The Allies abandoned the Treaty of Sèvres to negotiate a new treaty at Lausanne with the Turkish National Movement. The Treaty of Lausanne recognized the independence of the Republic of Turkey and its sovereignty over Anatolia, Istanbul, and Eastern Thrace. The Greek and Turkish governments agreed to engage in a population exchange.

Background

Geopolitical context

Map of the Megali Idea

The geopolitical context of this conflict is linked to the partitioning of the Ottoman Empire which was a direct consequence of World War I and involvement of the Ottomans in the Middle Eastern theatre. The Greeks received an order to land in Smyrna by the Triple Entente as part of the partition. During this war, the Ottoman government collapsed completely and the Ottoman Empire was divided amongst the victorious Entente powers with the signing of the Treaty of Sèvres on 10 August 1920.

There were a number of secret agreements regarding the partitioning of the Ottoman Empire at the end of World War I. The Triple Entente had made contradictory promises about post-war arrangements concerning Greek hopes in Asia Minor.

The western Allies, particularly British Prime Minister David Lloyd George, had promised Greece territorial gains at the expense of the Ottoman Empire if Greece entered the war on the Allied side. These included Eastern Thrace, the islands of Imbros (İmroz, since 29 July 1979 Gökçeada) and Tenedos (Bozcaada), and parts of western Anatolia around the city of Smyrna, which contained sizable ethnic Greek populations.

The Italian and Anglo-French repudiation of the Agreement of St.-Jean-de-Maurienne signed on 26 April 1917, which settled the "Middle Eastern interest" of Italy, was overridden with the Greek occupation, as Smyrna (İzmir) was part of the territory promised to Italy. Before the occupation the Italian delegation to the Paris Peace Conference, 1919, angry about the possibility of the Greek occupation of Western Anatolia, left the conference and did not return to Paris until 5 May. The absence of the Italian delegation from the Conference ended up facilitating Lloyd George's efforts to persuade France and the United States to support Greece and prevent Italian operations in Western Anatolia.

According to some historians, it was the Greek occupation of Smyrna that created the Turkish National movement. Arnold J. Toynbee argues: "The war between Turkey and Greece which burst out at this time was a defensive war for safeguarding of the Turkish homelands in Anatolia. It was a result of the Allied policy of imperialism operating in a foreign state, the military resources and powers of which were seriously under-estimated; it was provoked by the unwarranted invasion of a Greek army of occupation." According to others, the landing of the Greek troops in Smyrna was part of Eleftherios Venizelos's plan, inspired by the Megali Idea, to liberate the large Greek populations in the Asia Minor. Prior to the Great Fire of Smyrna, Smyrna had a bigger Greek population than the Greek capital, Athens. Athens, before the Population exchange between Greece and Turkey, had a population of 473,000, while the central kaza of Smyrna, according to Ottoman Census, in 1914, had a Greek population of 73.676 and the entire Aydın Vilayet including modern day İzmir, Manisa, Aydın and Denizli provinces had a Greek population of 299,096. While the sanjak of Muğla had a Greek population of 19,923

The Greek community in Anatolia

One of the reasons proposed by the Greek government for launching the Asia Minor expedition was that there was a sizeable Greek-speaking Orthodox Christian population inhabiting Anatolia that needed protection. Greeks had lived in Asia Minor since antiquity, and in 1912, there were 2.5 million Greeks in the Ottoman Empire. The Ottoman Census of 1906-1907 gives a higher figure for the entire Greek Orthodox population including Orthodox Albanians, Slavic-speakers, Vlachs, Arab Orthodox Christians, of the empire amounted to 2,823,063. According to the Ottoman Census of 1914 the Greek Orthodox population of Ottoman Empire after losing its Balkan & Aegean Island provinces, including 188,047 Arab Orthodox Christians from modern day Syria, Lebanon & Israel was 1,729,738. The suggestion that the Greeks constituted the majority of the population in the lands claimed by Greece has been contested by a number of historians. Cedric James Lowe and Michael L. Dockrill also argued that Greek claims about Smyrna were at best debatable, since Greeks constituted perhaps a bare majority, more likely a large minority in the Smyrna Vilayet, "which lay in an overwhelmingly Turkish Anatolia." Precise demographics are further obscured by the Ottoman policy of dividing the population according to religion rather than descent, language, or self-identification. On the other hand, contemporaneous British and American statistics (1919) support the point that the Greek element was the most numerous in the region of Smyrna, counting 375,000, while Muslims were 325,000.

Greek Prime Minister Venizelos stated to a British newspaper that "Greece is not making war against Islam, but against the anachronistic Ottoman Government, and its corrupt, ignominious, and bloody administration, with a view to expelling it from those territories where the majority of the population consists of Greeks."

To an extent, the above danger may have been overstated by Venizelos as a negotiating card on the table of Sèvres, in order to gain the support of the Allied governments. For example, the Young Turks were not in power at the time of the war, which makes such a justification less straightforward. Most of the leaders of that regime had fled the country at the end of World War I and the Ottoman government in Constantinople was already under British control. Furthermore, Venizelos had already revealed his desires for annexation of territories from the Ottoman Empire in the early stages of World War I, before these massacres had taken place. In a letter sent to Greek King Constantine in January 1915, he wrote that: "I have the impression that the concessions to Greece in Asia Minor ... would be so extensive that another equally large and not less rich Greece will be added to the doubled Greece which emerged from the victorious Balkan wars."

Through its failure, the Greek invasion may have instead exacerbated the atrocities that it was supposed to prevent. Arnold J. Toynbee blamed the policies pursued by Great Britain and Greece, and the decisions of the Paris Peace conference as factors leading to the atrocities committed by both sides during and after the war.

Greek irredentism

One of the main motivations for initiating the war was to realize the Megali (Great) Idea, a core concept of Greek nationalism. The Megali Idea was an irredentist vision of a restoration of a Greater Greece on both sides of the Aegean that would incorporate territories with Greek populations outside the borders of the Kingdom of Greece, which was initially very small — roughly half the size of the present-day Greek Republic. From the time of Greek independence from the Ottoman Empire in 1830, the Megali Idea had played a major role in Greek politics. Greek politicians, since the independence of the Greek state, had made several speeches on the issue of the "historic inevitability of the expansion of the Greek Kingdom." For instance, Greek politician Ioannis Kolettis voiced this conviction in the assembly in 1844: "There are two great centres of Hellenism. Athens is the capital of the Kingdom. Constantinople is the great capital, the City, the dream and hope of all Greeks."

The Great Idea was not merely the product of 19th century nationalism. It was, in one of its aspects, deeply rooted in many Greeks' religious consciousnesses. This aspect was the recovery of Constantinople for Christendom and the reestablishment of the Christian Byzantine Empire which had fallen in 1453. "Ever since this time the recovery of St. Sophia and the City had been handed down from generation to generation as the destiny and aspiration of the Greek Orthodox." The Megali Idea, besides Constantinople, included most traditional lands of the Greeks including Crete, Thessaly, Epirus, Macedonia, Thrace, the Aegean Islands, Cyprus, the coastlands of Asia Minor and Pontus on the Black Sea. Asia Minor was an essential part of the Greek world and an area of enduring Greek cultural dominance. In antiquity, from late Bronze Age up to the Roman conquest, Greek city-states had even exercised political control of most of the region, except the period ca. 550–470 BC when it was part of the Achaimenid Persian Empire. Later, during Middle Ages, the region had belonged to the Byzantine Empire until the 12th century, when the first Seljuk Turk raids reached it.

The National Schism in Greece

The National Schism in Greece was the deep split of Greek politics and society between two factions, the one led by Eleftherios Venizelos and the other by King Constantine, that predated World War I but escalated significantly over the decision on which side Greece should support during the war.

The United Kingdom had hoped that strategic considerations might persuade Constantine to join the cause of the Allies, but the King and his supporters insisted on strict neutrality, especially whilst the outcome of the conflict was hard to predict. In addition, family ties and emotional attachments made it difficult for Constantine to decide which side to support during World War I. The King's dilemma was further increased when the Ottomans and the Bulgarians, both having grievances and aspirations against the Greek Kingdom, joined the Central Powers.

Though Constantine did remain decidedly neutral, Prime Minister of Greece Eleftherios Venizelos had from an early point decided that Greece's interests would be best served by joining the Entente and started diplomatic efforts with the Allies to prepare the ground for concessions following an eventual victory. The disagreement and the subsequent dismissal of Venizelos by the King resulted in a deep personal rift between the two, which spilled over into their followers and the wider Greek society. Greece became divided into two radically opposed political camps, as Venizelos set up a separate state in Northern Greece, and eventually, with Allied support, forced the King to abdicate. In May 1917, after the exile of Constantine, Venizélos returned to Athens and allied with the Entente. Greek military forces (though divided between supporters of the monarchy and supporters of "Venizelism") began to take part in military operations against the Bulgarian Army on the border.

The act of entering the war and the preceding events resulted in a deep political and social division in post–World War I Greece. The country's foremost political formations, the Venizelist Liberals and the Royalists, already involved in a long and bitter rivalry over pre-war politics, reached a state of outright hatred towards each other. Both parties viewed the other's actions during the First World War as politically illegitimate and treasonous. This enmity inevitably spread throughout Greek society, creating a deep rift that contributed decisively to the failed Asia Minor campaign and resulted in much social unrest in the inter war years.

Greek expansion

The military aspect of the war began with the Armistice of Mudros. The military operations of the Greco-Turkish war can be roughly divided into three main phases: the first phase, spanning the period from May 1919 to October 1920, encompassed the Greek Landings in Asia Minor and their consolidation along the Aegean Coast. The second phase lasted from October 1920 to August 1921, and was characterised by Greek offensive operations. The third and final phase lasted until August 1922, when the strategic initiative was held by the Turkish Army.

Landing at Smyrna (May 1919)

On 15 May 1919, twenty thousand Greek soldiers landed in Smyrna and took control of the city and its surroundings under cover of the Greek, French, and British navies. Legal justifications for the landings was found in Article 7 of the Armistice of Mudros, which allowed the Allies "to occupy any strategic points in the event of any situation arising which threatens the security of Allies." The Greeks had already brought their forces into Eastern Thrace (apart from Constantinople and its region).

The Christian population of Smyrna (mainly Greeks and Armenians), according to different sources, either formed a minority or a majority compared to Muslim Turkish population of the city. The Greek army also consisted of 2,500 Armenian volunteers. The majority of the Greek population residing in the city greeted the Greek troops as liberators.

Greek summer offensives (Summer 1920)

During the summer of 1920, the Greek army launched a series of successful offensives in the directions of the Büyük Menderes River (Meander) Valley, Bursa (Prusa) and Alaşehir (Philadelphia). The overall strategic objective of these operations, which were met by increasingly stiff Turkish resistance, was to provide strategic depth to the defence of Izmir (Smyrna). To that end, the Greek zone of occupation was extended over all of Western and most of North-Western Anatolia.

Treaty of Sèvres (August 1920)

Partition of the Ottoman Empire according to the Treaty of Sèvres

In return for the contribution of the Greek army on the side of the Allies, the Allies supported the assignment of eastern Thrace and the millet of Smyrna to Greece. This treaty ended the First World War in Asia Minor and, at the same time, sealed the fate of the Ottoman Empire. Henceforth, the Ottoman Empire would no longer be a European power.

On 10 August 1920, the Ottoman Empire signed the Treaty of Sèvres ceding to Greece Thrace, up to the Chatalja lines. More importantly, Turkey renounced to Greece all rights over Imbros and Tenedos, retaining the small territories of Constantinople, the islands of Marmara, and "a tiny strip of European territory". The Straits of Bosporus were placed under an International Commission, as they were now open to all.

Turkey was furthermore forced to transfer to Greece "the exercise of her rights of sovereignty" over Smyrna in addition to "a considerable Hinterland, merely retaining a 'flag over an outer fort'." Though Greece administered the Smyrna enclave, its sovereignty remained, nominally, with the Sultan. According to the provisions of the Treaty, Smyrna was to maintain a local parliament and, if within five years time she asked to be incorporated within the Kingdom of Greece, the provision was made that the League of Nations would hold a plebiscite to decide on such matters.

The treaty was never ratified by the Ottoman Empire nor Greece.

Greek advance (October 1920)

In October 1920, the Greek army advanced further east into Anatolia, with the encouragement of Lloyd George, who intended to increase pressure on the Turkish and Ottoman governments to sign the Treaty of Sèvres. This advance began under the Liberal government of Eleftherios Venizelos, but soon after the offensive began, Venizelos fell from power and was replaced by Dimitrios Gounaris. The strategic objective of these operations was to defeat the Turkish Nationalists and force Mustafa Kemal into peace negotiations. The advancing Greeks, still holding superiority in numbers and modern equipment at this point, had hoped for an early battle in which they were confident of breaking up ill-equipped Turkish forces. Yet they met with little resistance, as the Turks managed to retreat in an orderly fashion and avoid encirclement. Churchill said: "The Greek columns trailed along the country roads passing safely through many ugly defiles, and at their approach the Turks, under strong and sagacious leadership, vanished into the recesses of Anatolia."

Change in Greek government (November 1920)

Anastasios Papoulas, commander-in-chief of the Greek Army of Asia Minor

During October 1920, King Alexander, who had been installed on the Greek throne on 11 June 1917 when his father Constantine was pushed into exile by the Venizelists, was bitten by a monkey kept at the Royal Gardens and died within days from sepsis. After King Alexander died without heirs, the legislative elections scheduled to be held on 1 November 1920, suddenly became the focus of a new conflict between the supporters of Venizelos and the Royalists. The anti-Venizelist faction campaigned on the basis of accusations of internal mismanagement and authoritarian attitudes of the government, which, due to the war, had stayed in power without elections since 1915. At the same time they promoted the idea of disengagement in Asia Minor, without though presenting a clear plan as to how this would happen. On the contrary, Venizelos was identified with the continuation of a war that did not seem to go anywhere. The majority of the Greek people were both war-weary and tired of the almost dictatorial regime of the Venizelists, so opted for change. To the surprise of many, Venizelos won only 118 out of the total 369 seats. The crushing defeat obliged Venizelos and a number of his closest supporters to leave the country. To this day his rationale to call elections at that time is questioned.

The new government under Dimitrios Gounaris prepared for a plebiscite on the return of King Constantine. Noting the King's hostile stance during World War I, the Allies warned the Greek government that if he should be returned to the throne they would cut off all financial and military aid to Greece .

A month later a plebiscite called for the return of King Constantine. Soon after his return, the King replaced many of the World War I Venizelist officers and appointed inexperienced monarchist officers to senior positions. The leadership of the campaign was given to Anastasios Papoulas, while King Constantine himself assumed nominally the overall command. The High Commissioner in Smyrna, Aristeidis Stergiadis, however was not removed. In addition, many of the remaining Venizelist officers resigned, appalled by the regime change.

A group of officers, headed by Georgios Kondylis, formed in Constantinople a "National Defence" organization, which reinforced with Venizelist deserters, soon started to criticize the royalist government of Athens.

The Greek Army which had secured Smyrna and the Asia Minor coast was purged of most of Venizelos's supporters, while it marched on Ankara. However, tension inside the Army between the two factions remained.

Battles of İnönü (December 1920 – March 1921)

Map showing the advance of the Greek army on the western front

By December 1920, the Greeks had advanced on two fronts, approaching Eskişehir from the North West and from Smyrna, and had consolidated their occupation zone. In early 1921 they resumed their advance with small scale reconnaissance incursions that met stiff resistance from entrenched Turkish Nationalists, who were increasingly better prepared and equipped as a regular army.

The Greek advance was halted for the first time at the First Battle of İnönü on 11 January 1921. Even though this was a minor confrontation involving only one Greek division, it held political significance for the fledgling Turkish revolutionaries. This development led to Allied proposals to amend the Treaty of Sèvres at a conference in London where both the Turkish Revolutionary and Ottoman governments were represented.

Although some agreements were reached with Italy, France and Britain, the decisions were not agreed to by the Greek government, who believed that they still retained the strategic advantage and could yet negotiate from a stronger position. The Greeks initiated another attack on 27 March, the Second Battle of İnönü, where the Turkish troops fiercely resisted and finally halted the Greeks on 30 March. The British favoured a Greek territorial expansion but refused to offer any military assistance in order to avoid provoking the French. The Turkish forces received arms assistance from Soviet Russia.

Shift of support towards the Turkish national movement

By this time all other fronts had been settled in favour of the Turks, freeing more resources for the main threat of the Greek Army. France and Italy concluded private agreements with the Turkish revolutionaries in recognition of their mounting strength. They viewed Greece as a British client, and sold military equipment to the Turks. The new Bolshevik government of Russia became friendly to the Turkish revolutionaries, as shown in the Treaty of Moscow (1921). The Bolsheviks supported Mustafa Kemal and his forces with money and ammunition. In 1920 alone, Bolshevik Russia supplied the Kemalists with 6,000 rifles, over 5 million rifle cartridges, and 17,600 shells as well as 200.6 kg (442.2 lb) of gold bullion. In the subsequent two years the amount of aid increased.

Battle of Afyonkarahisar-Eskişehir (July 1921)

Between 27 June and 20 July 1921, a reinforced Greek army of nine divisions launched a major offensive, the greatest thus far, against the Turkish troops commanded by İsmet İnönü on the line of Afyonkarahisar-Kütahya-Eskişehir. The plan of the Greeks was to cut Anatolia in two, as the above towns were on the main rail-lines connecting the hinterland with the coast. Eventually, after breaking the stiff Turkish defences, they occupied these strategically important centres. Instead of pursuing and decisively crippling the nationalists' military capacity, the Greek Army halted. In consequence, and despite their defeat, the Turks managed to avoid encirclement and made a strategic retreat on the east of the Sakarya River, where they organised their last line of defence.

This was the major decision that sealed the fate of the Greek campaign in Anatolia. The state and Army leadership, including King Constantine, Prime Minister Dimitrios Gounaris, and General Anastasios Papoulas, met at Kütahya where they debated the future of the campaign. The Greeks, with their faltering morale rejuvenated, failed to appraise the strategic situation that favoured the defending side; instead, pressed for a 'final solution', the leadership was polarised into the risky decision to pursue the Turks and attack their last line of defence close to Ankara. The military leadership was cautious and asked for more reinforcements and time to prepare, but did not go against the politicians. Only a few voices supported a defensive stance, including Ioannis Metaxas. Constantine by this time had little actual power and did not argue either way. After a delay of almost a month that gave time to the Turks to organise their defence, seven of the Greek divisions crossed east of the Sakarya River.

Battle of Sakarya (August and September 1921)

Following the retreat of the Turkish troops under İsmet İnönü in the battle of Kütahya-Eskişehir the Greek Army advanced afresh to the Sakarya River (Sangarios in Greek), less than 100 kilometres (62 mi) west of Ankara. Constantine's battle cry was "to Angira" and the British officers were invited, in anticipation, to a victory dinner in the city of Kemal. It was envisaged that the Turkish Revolutionaries, who had consistently avoided encirclement would be drawn into battle in defence of their capital and destroyed in a battle of attrition.

Despite the Soviet help, supplies were short as the Turkish army prepared to meet the Greeks. Owners of private rifles, guns and ammunition had to surrender them to the army and every household was required to provide a pair of underclothing and sandals. Meanwhile, the Turkish parliament, not happy with the performance of İsmet İnönü as the Commander of the Western Front, wanted Mustafa Kemal and Chief of General Staff Fevzi Çakmak to take control.

Greek forces marched 200 kilometres (120 mi) for a week through the desert to reach attack positions, so the Turks could see them coming. Food supplies were 40 tons of bread and salt, sugar and tea, the rest to be found on the way.

The advance of the Greek Army faced fierce resistance which culminated in the 21-day Battle of Sakarya (23 August – 13 September 1921). The Turkish defense positions were centred on series of heights, and the Greeks had to storm and occupy them. The Turks held certain hilltops and lost others, while some were lost and recaptured several times over. Yet the Turks had to conserve men, for the Greeks held the numerical advantage. The crucial moment came when the Greek army tried to take Haymana, 40 kilometres (25 mi) south of Ankara, but the Turks held out. Greek advances into Anatolia had lengthened their lines of supply and communication and they were running out of ammunition. The ferocity of the battle exhausted both sides but the Greeks were the first to withdraw to their previous lines. The thunder of cannon was plainly heard in Ankara throughout the battle.

That was the furthest in Anatolia the Greeks would advance, and within a few weeks they withdrew in an orderly manner back to the lines that they had held in June. The Turkish Parliament awarded both Mustafa Kemal and Fevzi Çakmak with the title of Field Marshal for their service in this battle. To this day no other person has received this five-star general title from the Turkish Republic.

Zvonarev, ambassador of Soviet Russia S.I. Aralov, Mustafa Kemal Pasha, ambassador of Azerbaijan SSR Ibrahim Abilov, commander of First Army Mirliva Ali Ihsan Pasha (Sâbis), in the morning of 31 March 1922.

Having failed to reach a military solution, Greece appealed to the Allies for help, but early in 1922 Britain, France and Italy decided that the Treaty of Sèvres could not be enforced and had to be revised. In accordance with this decision, under successive treaties, the Italian and French troops evacuated their positions, leaving the Greeks exposed.

In March 1922, the Allies proposed an armistice. Feeling that he now held the strategic advantage, Mustafa Kemal declined any settlement while the Greeks remained in Anatolia and intensified his efforts to re-organise the Turkish military for the final offensive against the Greeks. At the same time, the Greeks strengthened their defensive positions, but were increasingly demoralised by the inactivity of remaining on the defensive and the prolongation of the war. The Greek government was desperate to get some military support from the British or at least secure a loan, so it developed an ill-thought plan to force the British diplomatically, by threatening their positions in Constantinople, but this never materialised. The occupation of Constantinople would have been an easy task at this time because the Allied troops garrisoned there were much fewer than the Greek forces in Thrace (two divisions). The result though was instead to weaken the Greek defences in Smyrna by withdrawing troops. The Turkish forces, on the other hand, were recipients of significant assistance from Soviet Russia. On 29 April, the Soviet authorities supplied the Turkish consul critical quantities of arms and ammunition, sufficient for three Turkish divisions. On 3 May, the Soviet government handed over 33,500,000 gold rubles to Turkey—the balance of the credit of 10,000,000 gold rubles.

Voices in Greece increasingly called for withdrawal, and demoralizing propaganda spread among the troops. Some of the removed Venizelist officers organised a movement of "National Defense" and planned a coup to secede from Athens, but never gained Venizelos's endorsement and all their actions remained fruitless.

Historian Malcolm Yapp wrote that:

After the failure of the March negotiations the obvious course of action for the Greeks was to withdraw to defensible lines around Izmir but at this point fantasy began to direct Greek policy, the Greeks stayed in their positions and planned a seizure of Constantinople, although this latter project was abandoned in July in the face of Allied opposition.

Turkish counter-attack

The Turks finally launched a counter-attack on 26 August, what has come to be known to the Turks as the "Great Offensive" (Büyük Taarruz). The major Greek defense positions were overrun on 26 August, and Afyon fell next day. On 30 August, the Greek army was defeated decisively at the Battle of Dumlupınar, with many of its soldiers captured or slain and a large part of its equipment lost. This date is celebrated as Victory Day, a national holiday in Turkey and salvage day of Kütahya. During the battle, the Greek generals Nikolaos Trikoupis and Kimon Digenis were captured by the Turkish forces. General Trikoupis learned only after his capture that he had been recently appointed Commander-in-Chief in General Hatzianestis' place. According to the Greek Army General Staff, major generals Nikolaos Trikoupis and Kimon Digenis surrendered on 30 August 1922 by the village of Karaja Hissar due to lack of ammunitions, food and supplies On 1 September, Mustafa Kemal issued his famous order to the Turkish army: "Armies, your first goal is the Mediterranean, Forward!"

Turkish advance on Smyrna

On 2 September, Eskişehir was captured and the Greek government asked Britain to arrange a truce that would at least preserve its rule in Smyrna. However Mustafa Kemal Atatürk had categorically refused to acknowledge even a temporary Greek occupation of Smyrna, calling it a foreign occupation, and pursued an aggressive military policy instead. Balıkesir and Bilecik were taken on 6 September, and Aydın the next day. Manisa was taken on 8 September. The government in Athens resigned. Turkish cavalry entered Smyrna on 9 September. Gemlik and Mudanya fell on 11 September, with an entire Greek division surrendering. The expulsion of the Greek Army from Anatolia was completed on 18 September. As historian George Lenczowski has put it: "Once started, the offensive was a dazzling success. Within two weeks the Turks drove the Greek army back to the Mediterranean Sea."

The Burning of Smyrna as seen from an Italian ship, 14 September 1922

The vanguards of Turkish cavalry entered the outskirts of Smyrna on 9 September. On the same day, the Greek headquarters had evacuated the town. The Turkish cavalry rode into the town around eleven o'clock on the Saturday morning of 9 September. On 10 September, with the possibility of social disorder, Mustafa Kemal was quick to issue a proclamation, sentencing to death any Turkish soldier who harmed non-combatants. A few days before the Turkish capture of the city, Mustafa Kemal's messengers distributed leaflets with this order written in Greek. Mustafa Kemal said that the Ankara government would not be held responsible for any occurrence of a massacre.

Atrocities were committed against Greek and Armenian populaces, and their properties were pillaged. Most of the eye-witness reports identified troops from the Turkish army having set the fire in the city. The Greek and Armenian quarters of the city were burned, the Turkish as well as Jewish quarters stood.

Chanak Crisis

After re-capturing Smyrna, Turkish forces headed north for the Bosporus, the sea of Marmara, and the Dardanelles where the Allied garrisons were reinforced by British, French and Italian troops from Constantinople. In an interview with George Ward Price published in the Daily Mail, 15 September, Mustafa Kemal stated that: "Our demands remain the same after our recent victory as they were before. We ask for Asia Minor, Thrace up to the river Maritsa and Constantinople... We must have our capital and I should in that case be obliged to march on Constantinople with my army, which will be an affair of only a few days. I must prefer to obtain possession by negotiation though, naturally I cannot wait indefinitely."

Around this time, several Turkish officers were sent to infiltrate secretly into Constantinople to help organize Turkish population living in the city in the event of a war. For instance, Ernest Hemingway, who was at the time a war correspondent for the newspaper Toronto Star, reported that:

"Another night a [British] destroyer... stopped a boatload of Turkish women who were crossing from Asia Minor...On being searched for arms it turned out all the women were men. They were all armed and later proved to be Kemalist officers sent over to organize the Turkish population in the suburbs in case of an attack on Constantinople"

The British cabinet initially decided to resist the Turks if necessary at the Dardanelles and to ask for French and Italian help to enable the Greeks to remain in eastern Thrace. The British government also issued a request for military support from its Dominions. The response from the Dominions was negative (with the exception of New Zealand). Furthermore, Italian and French forces abandoned their positions at the straits and left the British alone to face the Turks. On 24 September, Mustafa Kemal's troops moved into the straits zones and refused British requests to leave. The British cabinet was divided on the matter but eventually any possible armed conflict was prevented. British General Charles Harington, allied commander in Constantinople, kept his men from firing on Turks and warned the British cabinet against any rash adventure. The Greek fleet left Constantinople upon his request. The British finally decided to force the Greeks to withdraw behind the Maritsa in Thrace. This convinced Mustafa Kemal to accept the opening of armistice talks.

Resolution

The Armistice of Mudanya was concluded on 11 October 1922. The Allies (Britain, France and Italy) retained control of eastern Thrace and the Bosporus. The Greeks were to evacuate these areas. The agreement came into force starting 15 October 1922, one day after the Greek side agreed to sign it.

The Armistice of Mudanya was followed by the Treaty of Lausanne. Separate from this treaty, Turkey and Greece came to an agreement covering an exchange of populations. Over one million Greek Orthodox Christians were displaced; most of them were resettled in Attica and the newly incorporated Greek territories of Macedonia and Thrace and were exchanged with about 500,000 Muslims displaced from Greek territories.

Factors contributing to the outcome

The Greeks estimated, despite warnings from the French and British not to underestimate the enemy, that they would need only three months to defeat the already weakened Turks on their own. Exhausted from four years of bloodshed, no Allied power had the will to engage in a new war and relied on Greece. During the Conference of London in February 1921, the Greek prime minister Kalogeropoulos revealed that the morale of the Greek army was excellent and their courage was undoubted, he added that in his eyes the Kemalists were "not regular soldiers; they merely constituted a rabble worthy of little or no consideration". Still, the Allies had doubts about Greek military capacity to advance in Anatolia, facing vast territories, long lines of communication, financial shortcomings of the Greek treasury and above all the toughness of the Turkish peasant/soldier. After the Greek failure to rout and defeat the new established Turkish army in the First and Second Battle of İnönü the Italians began to evacuate their occupation zone in southwestern Anatolia in July 1921. Furthermore, the Italians also claimed that Greece had violated the limits of the Greek occupation laid down by the Council of Four. France, on the other hand, had its own front in Cilicia with the Turkish nationalists. The French, like the other Allied powers, had changed their support to the Turks in order to build a strong buffer state against the Bolsheviks and were looking to leave. After the Greeks had failed again to knock out the Turks in the decisive Battle of Sakarya, the French finally signed the Treaty of Ankara (1921) with the Turks in late October 1921. In addition, the Allies did not fully allow the Greek Navy to effect a blockade of the Black Sea coast, which could have restricted Turkish imports of food and material. Still, the Greek Navy bombarded some larger ports (June and July 1921 Inebolu; July 1921 Trabzon, Sinop; August 1921 Rize, Trabzon; September 1921 Araklı, Terme, Trabzon; October 1921 Izmit; June 1922 Samsun). The Greek Navy was able to blockade the Black Sea coast especially before and during the First and Second İnönü, Kütahya–Eskişehir and Sakarya battles, preventing weapon and ammunition shipments.

Having adequate supplies was a constant problem for the Greek Army. Although it was not lacking in men, courage or enthusiasm, it was soon lacking in nearly everything else. Due to her poor economy, Greece could not sustain long-term mobilisation. According to a British report from May 1922, 60,000 Anatolian Greeks, Armenians and Circassians served under arms in the Greek occupation (of this number, 6,000–10,000 were Circassians). In comparison, the Turks also had difficulties to find enough fit men, as a result of 1.5 million military casualties during World War I. Very soon, the Greek Army exceeded the limits of its logistical structure and had no way of retaining such a large territory under constant attack by initially irregular and later regular Turkish troops. The idea that such large force could sustain offensive by mainly "living off the land" proved wrong. Although the Greek Army had to retain a large territory after September 1921, the Greek Army was more motorized than the Turkish Army. The Greek Army had in addition to 63,000 animals for transportation, 4,036 trucks and 1,776 automobiles/ambulances,(according to the Greek Army History Directorate total number of trucks, including ambulances, was 2500). Only 840 of them have been used for the advance to Angora, also 1.600 camels and a great number of ox and horse carts, whereas the Turkish Army relied on transportation with animals. They had 67,000 animals (of whom were used as: 3,141 horse carts, 1,970 ox carts, 2,318 tumbrels and 71 phaetons), but only 198 trucks and 33 automobiles/ambulances.

As the supply situation worsened for the Greeks, things improved for the Turks. After the Armistice of Mudros, the Allies had dissolved the Ottoman army, confiscated all Ottoman weapons and ammunition, hence the Turkish National Movement which was in the progress of establishing a new army, was in desperate need of weapons. In addition to the weapons not yet confiscated by the Allies, they enjoyed Soviet support from abroad, in return for giving Batum to the Soviet Union. The Soviets also provided monetary aid to the Turkish National Movement, not to the extent that they promised but almost in sufficient amount to make up the large deficiencies in the promised supply of arms. One of the main reasons for Soviet support was that Allied forces were fighting on Russian soil against the Bolshevik regime, therefore the Turkish opposition was much favored by Moscow. The Italians were embittered from their loss of the Smyrna mandate to the Greeks, and they used their base in Antalya to arm and train Turkish troops to assist the Kemalists against the Greeks.

A British military attaché, who inspected the Greek Army in June 1921, was quoted as saying, "more efficient fighting machine than I have ever seen it." Later he wrote: "The Greek Army of Asia Minor, which now stood ready and eager to advance, was the most formidable force the nation had ever put into field. Its morale was high. Judged by Balkan standards, its staff was capable, its discipline and organization good." Turkish troops had a determined and competent strategic and tactical command, manned by World War I veterans. The Turkish army enjoyed the advantage of being in defence, executed in the new form of 'area defence'.

Mustafa Kemal presented himself as revolutionary to the communists, protector of tradition and order to the conservatives, patriot soldier to the nationalists, and a Muslim leader for the religious, so he was able to recruit all Turkish elements and motivate them to fight. The Turkish National Movement attracted sympathizers especially from the Muslims of the far east countries. The Khilafet Committee in Bombay started a fund to help the Turkish National struggle and sent both financial aid and constant letters of encouragement. Not all of the money arrived, and Mustafa Kemal decided not use the money that was sent by the Khilafet Committee. The money was restored in the Ottoman Bank. After the war, it was later used for the founding of the Türkiye İş Bankası.

Atrocities and ethnic cleansing by both sides

Turkish genocides of Greeks and Armenians

Rudolph J. Rummel estimated that from 1900 to 1923, various Turkish regimes killed from 3,500,000 to over 4,300,000 Armenians, Greeks, and Assyrians. Rummel estimates that 440,000 Armenian civilians and 264,000 Greek civilians were killed by Turkish forces during the Turkish War of Independence between 1919 and 1922. However, he also gives the figures in his study of between 1.428 and 4.388 million dead of whom 2.781 millions were Armenian, Greek, Nestorians, Turks, Circassians and others, in line 488. British historian and journalist Arnold J. Toynbee stated that when he toured the region he saw numerous Greek villages that had been burned to the ground. Toynbee also stated that the Turkish troops had clearly, individually and deliberately, burned down each house in these villages, pouring petrol on them and taking care to ensure that they were totally destroyed. There were massacres throughout 1920–23, the period of the Turkish War of Independence, especially of Armenians in the East and the South, and against the Greeks in the Black Sea Region. Ultimately, by 1922, the majority of Ottoman Greeks of Anatolia had either become refugees or had died.

Greeks suffered in the Turkish labor battalions. Many of the Greek deportations involved chiefly women and children as, by early 1915, most army-age Greek men had been mobilized in Ottoman labor battalions or had fled their homes to avoid conscription. According to Rendel, atrocities such as deportations involving death marches, starvation in labour camps etc. were referred to as "white massacres". Ottoman official Rafet Bey was active in the genocide of the Greeks and in November 1916, Austrian consul in Samsun, Kwiatkowski, reported that he said to him "We must finish off the Greeks as we did with the Armenians ... today I sent squads to the interior to kill every Greek on sight".

Sivas province governor Ebubekir Hâzım Tepeyran said in 1919 that the massacres were so horrible that he could not bear to report them. He referred to the atrocities committed against Greeks in the Black Sea region, and according to the official tally 11,181 Greeks were murdered in 1921 by the Central Army under the command of Nurettin Pasha (who is infamous for the killing of Archbishop Chrysostomos). Some parliamentary deputies demanded that Nurettin Pasha be sentenced to death and it was decided to put him on trial, although the trial was later revoked by the intervention of Mustafa Kemal. Taner Akçam wrote that according to one newspaper, Nurettin Pasha had proposed the killing of all the remaining Greek and Armenian populations in Anatolia, a suggestion rejected by Mustafa Kemal.

There were also several contemporary Western newspaper articles reporting the atrocities committed by Turkish forces against Christian populations living in Anatolia, mainly Greek and Armenian civilians.

Atrocities against Pontic Greeks living in the Pontus region is recognized in Greece and Cyprus as the Pontian Genocide. According to a proclamation made in 2002 by the then-governor of New York (where a sizeable population of Greek Americans resides), George Pataki, the Greeks of Asia Minor endured immeasurable cruelty during a Turkish government-sanctioned systematic campaign to displace them; destroying Greek towns and villages and slaughtering additional hundreds of thousands of civilians in areas where Greeks composed a majority, as on the Black Sea coast, Pontus, and areas around Smyrna; those who survived were exiled from Turkey and today they and their descendants live throughout the Greek diaspora.

By 9 September 1922, the Turkish army had entered Smyrna, with the Greek authorities having left two days before. Large scale disorder followed, with the Christian population suffering under attacks from soldiers and Turkish inhabitants. On 13 September, a fire from the Armenian quarter of the city had engulfed the Christian waterfront of the city, leaving the city devastated. Some 50,000 to 100,000 Greeks and Armenians were killed in the fire and accompanying massacres.

Greek massacres of Turks

Turkish medics arrived at a town to rescue wounded on the way to Izmir after Greek forces abandoned the town (August 1922).

British historian Arnold J. Toynbee wrote that there were organized atrocities following the Greek landing at Smyrna on 15 May 1919. He also stated that he and his wife were witnesses to the atrocities perpetrated by Greeks in the Yalova, Gemlik, and Izmit areas. Secretary of State for the Colonies and later Prime Minister of the United Kingdom, Winston Churchill comparing the specific activities with the genocide policies perpetrated by the Turkish side noted that the Greek atrocities were on "a minor scale" compared to the "appalling deportations of Greeks from the Trebizond and Samsun district."

During the Battle of Bergama, the Greek army committed a massacre against Turkish civilians in Menemen killing 200 and injuring 200 people. Some Turkish sources claim that the death count of the Menemen massacre was 1000. On 24 June 1921, a massacre occurred in İzmit, resulting in the death of more than 300 Turkish civilians.

Justin McCarthy reports that during the negotiations for the Treaty of Lausanne, the chief negotiator of the Turkish delegation, Ismet Pasha (İnönü), gave an estimate of 1.5 million Anatolian Muslims that had either been exiled or died in the areas of the Greek occupation zone. McCarthy lowers the estimate to 1,246,068 Muslim population loss between 1914 and 1922 in Anatolia, and arbitrarily ascribes 640,000 of those as occurring in both the Greek and British zones of operation in 1919–1922. McCarthy's work has faced harsh criticism by scholars who have characterized McCarthy's views as indefensibly biased towards Turkey and the Turkish official position as well as engaging in genocide denial. Other scholars, such as R.J. Rummel and Michael Clodfelter give considerably lower estimates, 15,000 Turkish civilian deaths.

As part of the Lausanne Treaty, Greece recognized the obligation to pay reparations for damages caused in Anatolia, though Turkey agreed to renounce all such claims due to Greece's difficult financial situation.

Greek scorched-earth policy

Western Anatolian towns that were burnt down in 1919 – 22 according to the report of the Turkish delegation in Lausanne

According to a number of sources, the retreating Greek army carried out a scorched-earth policy while fleeing from Anatolia during the final phase of the war. Historian of the Middle East, Sydney Nettleton Fisher wrote that: "The Greek army in retreat pursued a burned-earth policy and committed every known outrage against defenceless Turkish villagers in its path." Norman M. Naimark noted that "the Greek retreat was even more devastating for the local population than the occupation".

The Greek Army not only carried out a scorched-earth policy on its retreat, but also during its advance. This can be seen also in the diary of the Cretan Greek lieutenant Pantelis Priniotakis from Rethymno. In his diary dating to 13 July 1921, he states that his advancing unit, after a little resistance, captured and burned the town of Pazarcık in just a few hours, while its population fled once they saw the advancing Greek Army.

Zeytinler village in Urla, Memorial for the Civilians Casualties of the Village

Johannes Kolmodin was a Swedish orientalist in Smyrna. He wrote in his letters that the Greek army had burned 250 Turkish villages.

Greek scorched-earth policy also included mass slaughter of livestock.

Population Exchange

According to the population exchange treaty signed by both the Turkish and Greek governments, Greek orthodox citizens of Turkey and Turkish and Greek Muslim citizens residing in Greece were subjected to the population exchange between these two countries. Approximately 1,500,000 Orthodox Christians, being ethnic Greeks and ethnic Turks from Turkey and about 500,000 Turks and Greek Muslims from Greece were uprooted from their homelands. M. Norman Naimark claimed that this treaty was the last part of an ethnic cleansing campaign to create an ethnically pure homeland for the Turks Historian Dinah Shelton similarly wrote that "the Lausanne Treaty completed the forcible transfer of the country's Greeks."

A large part of the Greek population was forced to leave their ancestral homelands of Ionia, Pontus and Eastern Thrace between 1914 and 1922. These refugees, as well as Greek Americans with origins in Anatolia, were not allowed to return to their homelands after the signing of the Treaty of Lausanne.
