Ottoman ironclad Necm-i Şevket

The Ottoman fleet began mobilizing in September 1876 to prepare for a conflict with Russia, as tensions with the country had been growing for several years, an insurrection had begun in Ottoman Bosnia in mid-1875, and Serbia had declared war on the Ottoman Empire in July 1876. The Russo-Turkish War began on 24 April 1877 with a Russian declaration of war.[6] Necm-i Şevket spent the war in the Black Sea squadron, with the bulk of the Ottoman ironclad fleet.[7] The Ottoman fleet, commanded by Hobart Pasha, was vastly superior to the Russian Black Sea Fleet; the only ironclads the Russians possessed there were Vitse-admiral Popov and Novgorod, circular vessels that had proved to be useless in service.[8] The presence of the fleet did force the Russians to keep two corps in reserve for coastal defense, but the Ottoman high command failed to make use of its naval superiority in a more meaningful way, particularly to hinder the Russian advance into the Balkans.[9] Hobart Pasha took the fleet to the eastern Black Sea, where he was able to make a more aggressive use of it to support the Ottoman forces battling the Russians in the Caucasus. The fleet bombarded Poti and assisted in the defense of Batumi.[10]

On 14 May 1877, an Ottoman squadron consisting of Necm-i Şevket and the ironclads Avnillah, Muin-i Zafer, Feth-i Bülend, Mukaddeme-i Hayir, and Iclaliye bombarded Russian positions around the Black Sea port of Sokhumi before landing infantry and arming the local populace to start an uprising against the Russians. The Ottomans captured Sokhumi two days later. Over the course of the war, Russian torpedo boats made several attacks on the vessels stationed in Batumi, but Necm-i Şevket was not damaged in any of them.[11][12] The Ottoman fleet continued to support the Ottoman garrison at Batumi, when held out against constant Russian attacks to the end of the war.[13]

After the end of the war in 1878, Necm-i Şevket was laid up in Constantinople.[3] This was in part due to chronically low budgets, and in part due to the fact that the Sultan, Abdul Hamid II, who had come to power after a coup deposed Murad V that involved senior members of the Navy, distrusted the Navy.[2] In 1890, the ship was taken to the Imperial Arsenal for refitting, and new boilers were installed. The ship also received a battery of light guns, including two 87 mm (3.4 in) Krupp guns, two 63.5 mm (2.50 in) Krupp guns, two 37 mm (1.5 in) Hotchkiss revolver cannon, and one 25.4 mm (1 in) Nordenfelt gun. The ship returned to service on 12 February 1892.[3]

At the start of the Greco-Turkish War in February 1897, Necm-i Şevket was assigned to the II Squadron.[5] The Ottomans inspected the fleet and found that almost all of the vessels, including Necm-i Şevket, to be completely unfit for combat against the Greek Navy. Many of the ships had rotted hulls and their crews are poorly trained. Necm-i Şevket was one of two ironclads found to be in usable condition, the other being Mesudiye. In April and May, the ship escorted troopships transporting infantry from western Anatolia to Gelibolu, and while conducting these operations, she took part in gunnery exercises. On 15 May, Necm-i Şevket and the ironclads Mesudiye, Osmaniye, Aziziye, and Hamidiye, along with several other vessels conducted a major training exercise, where severe deficiencies in the level of training were revealed, particularly with the men's ability to operate the ships' guns. In September 1897, the war came to an end, and the Ottoman fleet returned to Constantinople.[14]

The condition of the Ottoman fleet could not be concealed from foreign observers, which proved to be an embarrassment for the government and finally forced Abdul Hamid II to authorize a modernization program, which recommended that the ironclads be modernized in foreign shipyards. German firms, including Krupp, Schichau-Werke, and AG Vulcan, were to rebuild the ships, but after having surveyed the ships, withdrew from the project in December 1897 owing to the impracticality of modernizing the ships and the inability of the Ottoman government to pay for the work. By 1900, the contracts were finally awarded, and Necm-i Şevket was not included in the program.[15] Instead, the ship was employed as a stationary ship based in Selanik from 1899 to 1909, at which point she was converted into a barracks ship in Constantinople.[3]

On 30 October 1912, during the First Balkan War, Necm-i Şevket was reactivated to stop the Bulgarian advance against the Ottoman defenders at Çatalca.[16] She was joined by the ironclad Iclaliye; both vessels had to be towed into place, and they remained in their firing positions for only a few days.[17] The two ships, joined by the pre-dreadnought battleships Barbaros Hayreddin and Torgud Reis and the modernized Mesudiye and Asar-i Tevfik, were towed to Büyükçekmece, where they remained from 15 to 20 November, though they made little contact with Bulgarian forces.[16] The ship resumed her barracks ship duties after the war and was decommissioned in 1929 and was thereafter broken up.[3]
