# XV Corps (Ottoman Empire)

The XV Corps of the Ottoman Empire (Turkish: 15'inci Kolordu or On Beşinci Kolordu) was one of the corps of the Ottoman Army. It was formed during World War I.
480 soldiers of the XV Corps, who fought on the Galicia front and died, are buried at the Budapest Turkish Memorial Cemetery within the New Public Cemetery (Hungarian: Új köztemető) in Budapest, Hungary. Eleven graves are of unknown soldiers.

## World War I
### Eastern Front

The XV Corps fought with distinction in several engagements. Their first combat engagement was on September 2, 1916. On September 16/17 the Russians attacked the XV Corps with emphasis on the 61st Regiment, but were forced back and counterattacked by the Ottomans. Ottoman casualties on these two days were 7,000 while Russian casualties totaled 15,000-20,000, which stabilized the XV Corps' section of the front for the next two weeks. On September 30 the Russians launched another attack, but were repulsed again; Turkish casualties were 5,000 while Russian casualties were unknown but presumably much higher (10,000+). On October 5/6 the Russians renewed their offensive with a 13-regiment attack on the southern part of the Ottoman line; they took Cevatbey Hill after heavy losses, but were soon forced back again. Ottoman casualties on those two days were 3,000 compared to 12,000 Russian casualties. November and December 1916 passed without any serious fighting with the Russians.
In early November, the tactical situation on the Turkish sector of the front was so favorable that the Germans withdrew their Ledabor detachments. Large-scale Russian attacks occurred throughout December, but the Turks repulsed them without any loss of ground. Turkish casualties were around 3,000 in November and December. Overall losses for 1916 numbered 18,000: 5,000 killed, 10,000 wounded, and 3,000 captured.
Having suffered heavy casualties in September–December 1916, the XV Corps was replenished with fresh troops from Turkey at the start of 1917. The strength of the XV Army Corps rose to 27,031 men with another 5,668 men training in regimental depots by the end of January. The corps was also significantly reinforced with new units which enhanced its fighting efficiency, such as artillery batteries, intelligence and labor detachments, an aircraft company, a balloon detachment, a field bakery company, transportation units and a veterinary hospital. On January 22 successful Turkish commanders and troops were decorated with the German Iron Cross. On 4 February in a show of solidarity, Brigadier General Cevat Paşa paid a visit to Kaiser Wilhelm himself.
On the morning of March 5, 1917, the Russians preluded a three-division attack on a part of the Turkish sector with heavy artillery bombardment. However, the Russians had launched an attack while the XV Corps occupied the very defensible high ground overlooking Zlotalpia River valley and repulsed the Russians. A similar attack was repulsed in April 1917. May passed without further incident, but near the end of June the Russians renewed the offensive. The fighting continued to intensify and on July 1 the Russians attempted to dislodge the Turks with gas shells. By July 11, the fighting had mostly subsided. Russian losses in the June–July offensive were 13,000, while the Turkish losses were reported as 2,550 from June 29 to July 2, 1916 alone. Russian losses in the March and April attacks are unknown.
In early August 1917 the Turkish General Staff decided to withdraw the XV Corps from Galicia and redeploy it to Palestine, and by September 26, 1917 the final units of the XV Corps had been transported to Constantinople. By that time, the XV Army Corps had inflicted well over 72,000 casualties on the opposing Russian forces and held their sector of the line against at least five major attacks, while similarly-sized Austro-Hungarian formations folded to similar attacks around the same time even with German back-up. German General Erich von Falkenhayn claimed in his memoirs that the Turks were "an uncommonly valuable asset to the Southern Army", and allowed the Germans to marshall troops elsewhere in line with their economy of force mission. However, Liman Von Sanders argued that the experienced and well-equipped troops of the XV Corps could've been better used in the Middle Eastern Theater, as in the same year where the XV Corps scored its successes in Galicia, the Ottomans suffered a series of catastrophic defeats against the Russians and British back in their own territory, losing Erzincan in the Caucasus and Gaza in Palestine.
The Ottoman XV Army Corps sustained overall losses of around 25,000 in Galicia.
