In 1904, Fethi began his duty as a staff captain in the
Third Army in
Salonika in the 13th Cavalry Regiment. During his internship training he came face to face with Bulgarian, Serbian, and Greek
chetas and committee units. He was promoted to the rank of
Kolağası in 1906. On 30 April 1906 he was appointed as an assistant course supervisor at the
Edirne War School, despite his wishes. He was soon appointed to Third Army's
Mahçova (
Metsovo) Greek Border Zone Command in August 1906. On 1 March 1907 he was appointed to the Salonika Eastern Railway Line Inspectorate. While on the staff of the Third Army Marshal İbrahim Pasha, he played an important role in the clashes with Greek committee bands, which became more active after the Reval meeting between King
Edward VII and
Tsar Nicholas II, and in Strebne. Upon the suggestion of
Rumelia Inspector
Hüseyin Hilmi Pasha, he was appointed as the commander of the Salonika Gendarmerie Officer's School on 21 March 1908 and promoted to the rank of "Major".
Revolutionary career In 1907, he was indicted into the
Committee of Union and Progress by one of the members of the General Staff, Major İsmail Hakkı. Hakkı advised him to go to
Manastir (
Bitola) and asked him to meet
İsmail Enver Bey, where he was initiated with Enver's guidance. He returned to Kesriye (
Kastoria) opened a CUP cell there. He quickly became an important member, becoming a member of the Salonika central committee with İsmail Canbulat,
Mithat Şükrü, Topçu Rasim, and Hamdi. During this period of military service, he also worked to induct new members for the CUP. When Mustafa Kemal was assigned to the Third Army in Selanik in October 1907, Fethi made sure to induct him into the committee, and also for
Mustafa İsmet (İnönü). As membership in the committee increased, new branches cells were formed, many of which were administered by him. After Paris and Salonika became the two centers of the CUP, it was Fethi that handled communication between Salonika and other branches. Following the Reval meetings between King
Edward VII and
Tsar Nicholas II, on June 25, 1908, Ali Fethi Bey and the leading figures of the CUP gathered at the house of Manyasizade Refik Bey, the chief of the Salonika branch, to discuss a response. These events initiated the beginning of the
Young Turk Revolution. It was decided that the Unionists should rise in revolt and that if necessary, the incoming Hamidian agents, principally
Şemsi Pasha, must be killed. On 3 July 1908, a group of 150 people, including
Reşneli Ahmed Niyazi began an uprising from which many Rumelian cities joined in revolution. After demonstrations in places like Salonika,
Serres,
İştip,
Priştina in support of the constitution Ali Fethi and the leading Unionists again gathered at Manyasizade Refik's house.
Atıf Kamçıl advocated for assassinating Şemsi Pasha and personally executed the plan. Şemsi was shot dead by Lieutenant Atıf at the entrance of the Manastır Post Office on 7 July. On the night of 22–23 July, another Unionist meeting was held at Manyasizade Refik's house. It was decided per
Mehmet Talât's suggestion that they should prepare a declaration of constitutional monarchy. Talât asked Fethi to write the declaration himself, and this proposal was also accepted in another vote. While the meeting continued, Ali Fethi wrote the declaration in another room. He was appointed the Paris
Military Attaché by the
Minister of War Mahmut Şevket Pasha on 12 January 1909, but took up his post in March, serving until 1911. During his duty he returned to Salonika to participate in the
Action Army. Returning from Istanbul, he accompanied
Abdul Hamid II to his house arrest in Salonika, serving as a guard at the
Villa Allatini for more than three months. During his second period as attaché to Paris, between 12–18 September 1910 Fethi observed the
Picardie maneuvers that France carried out as a response to the maneuvers that Germany carried out in the Rhine region. He followed the maneuvers with Mustafa Kemal and
Hüseyin Selahattin Bey. He spent most of his time between 1910–1911 writing reports on the maneuvers and informing the capital and the General Staff. During the
Malissori uprising on 25 June 1911 his request to join the Shkodra War Staff was granted, which he served for a three months.
Tripolitanian war On 29 September 1911,
Italy declared war on
Ottoman Turkey for
Tripolitania. Due to the Ottoman government's belief that the issue would be resolved through diplomatic means, the CUP leaders decided to take matters into their own hands. Ten Unionists including Ali Fethi, Mustafa Kemal, Eşref Kuşçubaşı, and
Süleyman Askerî gathered at Enver's house. After the meeting, it was decided they would organize a resistance. Ali Fethi went by way of Paris with Ambassador Rıfat's assistance. He also asked for help from
SFIO leaders
Jean Jaures and
Pierre Loti, and the two of them wrote articles criticizing the Italian occupation. Fethi first reached the port of
Sfax in
French Tunisia with five military medical doctors and a boatman from Marseille, and arrived in
Tripoli on 12 October 1911. He was appointed chief of staff of the 42nd Division, commanded by Colonel Neşet Pasha, and took to organizing local militia groups against the Italians. During his activities around Tripoli, on 3 November he reported to the division command that Italian soldiers were abusing the civilian population, and he requested that this situation be protested by the European states. Fethi played an important role in the
Battle of Ain Zara, but outnumbered and outgunned, the Italians took the oasis. However the Italians couldn't advance beyond Ain Zara into December and January, they lost control over Sedra, failed to take Homs and retreated back to Ain Zara. Responding to the stalemate in Libya, Italy
invaded the Dodecanese between April 23 and May 17. In April 1912, he was elected deputy of Monastir in that year's
general election for the
Chamber of Deputies. After the
closure of the Chamber, he returned to Tripoli. However by the start of the
First Balkan War, Ali Fethi and other officers had to return to the capital.
Balkan Wars Fethi was given command over the
Dardanelles Strait Staff on 25 November 1912. When the
London Conference was unsuccessfully dispersed on 29 January 1913, the Bulgarian armies resumed
their offensive on the Çatalca line,
surrounded Edirne, and advanced on the
Gallipoli peninsula; squeezing the
Bolayır Corps into a narrow line, where Fethi and Kemal fought alongside each other. Battle plans were drawn up for an operation to relieve Edirne, which included an amphibious landing at the
Bolayır line and
Şarköy. The aim was to surround the Bulgarians between the two lines. However due to the complexity of the operation and last minute criticisms the two forces failed to link up and land on time. The Tenth Corps commanded by Hurşit Pasha and Staff Officer Enver Pasha, landed successfully, but Bolayır Corps commanded by Fahri Pasha and Staff Officer Ali Fethi (Mustafa Kemal Director of the Operations Department) suffered many casualties upon landing in Şarköy. Despite all the losses, Enver Pasha insisted on attacking Şarköy again, despite Fahri Pasha, Ali Fethi and Mustafa Kemal's opposition. The commanders of the two corps blamed each other for the defeat. As a result of the defeat, Ali Fethi and Mustafa Kemal attempted to submit their resignations, but they were not accepted. The Bulgarians captured Edirne on March 26, and the city was lost with the
Treaty of London on May 30, 1913. In July 1913, the
Second Balkan War broke out over Bulgaria and Serbia's disagreements over captured territory, and the Ottoman Empire soon entered the war to retake lost Rumelian territory. Fethi's
Bolayır Corps participated in the operations to retake Edirne from Bulgaria, but Enver Pasha's troops retook the city first. Fethi resigned from military service immediately after returning from the war on September 14, 1913. == Last days of the Ottoman Empire ==
