The Great Offensive and Dumlupınar

Why waiting after Sakarya meant preparation

The defensive success of autumn 1921 did not establish that the army could immediately launch a decisive offensive. The intervening months involved training, organisation, equipment and concentration. Holding a defensive position and breaking an opposing line while sustaining movement over distance impose different requirements. Preparation is not an empty interval between events; it is work through which an eventual military result becomes possible.

Parliamentary criticism and expectations about timing reveal the political responsibility of command. Mustafa Kemal's contribution extended beyond being at the front when artillery opened fire. Assessing readiness and the appropriate moment with the command structure formed part of that leadership. Knowing the outcome now should not make every contemporary worry about the waiting period seem meaningless.

A command structure larger than one photograph

Commander-in-chief Mustafa Kemal, Chief of the General Staff Fevzi Pasha and Western Front commander İsmet Pasha held different responsibilities. Nurettin Pasha commanded the First Army and Yakup Şevki Pasha the Second. Corps, divisions and regiments translated a plan into action on the ground. These distinctions make it possible to describe Atatürk's decisive leadership without attributing every contribution to one individual.

Etem Tem's Kocatepe photograph became an emblem of the period, not a complete representation of an army's work. Headquarters staff, messengers, ammunition personnel and soldiers outside its frame were also participants. Preserving the photograph's value means not presenting it as direct evidence of every decision or engagement elsewhere. Here it is captioned conservatively to the 1922 offensive period rather than assigned a disputed exact day.

26–27 August: concentrating south of Afyon

The attack against defences south of Afyonkarahisar began on the morning of 26 August. Concentrating troops and fire in a selected sector is not the same as attacking with equal intensity everywhere. Seeking local advantage aimed to break a position and open space for further movement. Comparing only the armies' overall sizes would conceal where and how the plan operated.

Kocatepe mattered for observation and command; the heights around Kalecik, Tınaz and Belen mattered for defence and approaches. Separating them on a map prevents monument names from substituting for geography. The opening attacks and developments around Afyon on 27 August were successive phases. Breaking a defensive line did not automatically complete pursuit and encirclement.

Cavalry, reconnaissance and supply

Fahrettin Altay's cavalry played important roles in movement behind the front and along transport connections. Cavalry was not simply a fast-moving ceremonial image: it required information, navigation, liaison and supplies. Coordination between the main attack and movement behind the opposing forces affected opportunities for encirclement.

Air reconnaissance contributed to command's information, as Fazıl Bey's biography helps demonstrate. Horses, aircraft and artillery nevertheless had different transport, maintenance and fuel or fodder requirements. Moving materials between local communities and the front exposes the social labour behind victory. An accelerating advance did not make supply less important; keeping support moving with formations could become more difficult.

28 August: pursuit routes

Çaykıran's published chronology places Mustafa Kemal in Afyon and then Balmahmut on 28 August, urging continued pursuit. Entry into Afyon had not ended the operation. Moving command forward should be read alongside the need to maintain pressure on forces beyond the breached front.

Fevzi Çakmak's speech of 30 August 1924 describes the Second and Fourteenth Cavalry Divisions crossing north of the railway towards Ulucak and Eğret on the night of 27–28 August. Infantry taking positions and cavalry reaching withdrawal routes were different tasks; combining them made regrouping harder.

29 August: towards Çalköy

The same speech describes the First Corps' Third and Twenty-third Divisions reaching Çalköy on 29 August and attacking towards Aslıhanlar to cut withdrawal towards Dumlupınar. Çalköy and Aslıhanlar were separate operational locations, not two names for one monument. This is a commander's later assessment, not a battle-day report.

Çaykıran describes Mustafa Kemal assessing incoming information with Fevzi and İsmet Pashas in Afyon on the night of 29–30 August. The next decision responded to ongoing fighting.

TRT records some Greek units escaping through an opening towards Kızıltaş stream on 30 August. Encirclement was not a perfect, motionless ring: seeking to block routes differs from closing every passage simultaneously. That distinction also explains why pursuit continued after the decisive engagement.

30 August and pursuit: keep the dates distinct

The Commander-in-Chief Battle on 30 August was the decisive phase around Aslıhanlar, Çalköy and Dumlupınar, severely defeating the main Greek forces. Disruption of an army's fighting organisation does not mean every soldier was captured in one place that day. General Trikopis was taken prisoner on 2 September; moving this event into 30 August would distort chronology.

Westward advance and pursuit along different directions followed. Turkish troops entered İzmir on 9 September, one of the campaign's major outcomes. Not every town was regained on that date. The opening offensive, decisive engagement, pursuit and entry into cities are separate milestones. Their distinction also clarifies why Victory Day commemorates 30 August in particular.

From military outcome to armistice and peace

The military balance in western Anatolia changed, but the Straits, Istanbul and Eastern Thrace remained unresolved. Negotiations and the Mudanya Armistice of 11 October 1922 moved the achievement into another political phase. The Lausanne Peace Treaty of 24 July 1923 was neither the same document nor the same event. Ending operations and establishing a final international settlement should be distinguished.

Restoring civilian life was another process. Bereaved families, wounded or disabled veterans and people needing assistance must not disappear from celebration. When visiting historical sites, distinguish a monument's opening from the battle date, and a veteran's later recollection from a contemporary report. A strong account of victory also makes its human cost, subsequent diplomacy and reconstruction work visible.
