The Battle of Ctesiphon (Turkish: Selman-ı Pak Muharebesi) was fought in November 1915 by the British Empire, against the Ottoman Empire, within the Mesopotamian Campaign of World War I. Indian Expeditionary Force D, mostly made up of Indian units and under the command of Gen. Sir John Nixon, had met with success in Ottoman Iraq since it had landed at Al-Faw Peninsula upon the Ottoman Empire's declaration of war on 5 November 1914. One of the primary reasons for initiating the campaign in Mesopotamia was to defend the oil refinery at Abadan at the mouth of the Shatt al-Arab. Adopting a forward defence policy, the British army under General Townshend fought off a series of small Ottoman forces. Then after a year of a string of defeats, the Ottoman forces were able to halt the British advance in two days of hard fighting at Ctesiphon.
