Early in 1915, the previous head of the German military mission to the Ottoman Empire, Baron von der Goltz, arrived in Istanbul as military advisor to the (essentially powerless) Sultan, Mehmed V. The old Baron did not get along with Liman von Sanders and did not like the three Pashas (Enver Pasha, Cemal Pasha and Talat) who ran the Ottoman Empire during the war. The Baron proposed some major offensives against the British, but these proposals came to nothing in the face of Allied offensives against the Ottomans on three fronts (the Dardanelles, the Caucasus Front, and the newly opened Mesopotamian Front). Liman was rid of the old Baron when Enver Pasha sent him to fight the British in Mesopotamia in October 1915. (Goltz died there six months later, just before the British army at Kut surrendered.)
