British forces involved in Mesopotamia
(Mesopotamia Expeditionary Force / Indian Expeditionary Force "D")

The force fighting in Mesopotamia was principally one of the Indian Army, with only one solely British formation, the 13th (Western) Division. The Indian formations contained some British units.

  • 6th (Poona) Division (first elements left India October 1914)
  • 12th Indian Division (formed in Mesopotamia March 1915)
  • 13th (Western) Division (arrived from Gallipoli via Egypt February 1916)
  • 3rd (Lahore) Division (arrived from France April 1916)
  • 7th (Meerut) Division (arrived from France April 1916)
  • 14th Indian Division (formed in Mesopotamia May 1916)
  • 15th Indian Division (formed in Mesopotamia May 1916)
  • 17th Indian Division (formed in Mesopotamia August 1917)
  • 18th Indian Division (formed in Mesopotamia December 1917)

Battles and engagements


LocationFor centuries before the Great War, Mesopotamia had been part of the Turkish Ottoman Empire. Lying along its eastern border was Persia, generally friendly to the British. The Arab Sheiks of nearby Kuwait and Muhammerah also supported Britain; the Arab tribes of coastal Mesopotamia often changed sides. Germany had for many years before the war assiduously developed Turkey as an ally, which it saw as an important part of the Drang nach Osten ("Thrust towards the East": Germany wanted new lands, new markets, "lebensraum"). The Turkish army was led by German 'advisors', as was much of its trade and commerce. Although this campaign began simply to secure oil supplies for teh Royal Navy, victory over the Turks became believed by some - notably David Lloyd George and Winston Churchill - to be a less costly way towards defeat of Germany than the painful battering at the Western Front. Pushed by Germany - which also tried to encourage a Jihad (Muslim Holy War) against the British forces - Turkey was to strongly resist the British incursion

The ground

MapMesopotamia is an ancient land, through which run the great Rivers Tigris and Euphrates. At the southern end, this is a complex river delta. The two rivers meet at Qurna, 40 miles north of Basra, where they come together to form the Shatt-al-Arab, which flows into the Persian Gulf. The land is for the most part desert and is very flat. The rivers flood the plains to a great extent, when the winter snows in the northern mountains thaw. The small towns and villages that existed along the river banks in 1914 were generally constructed several feet above water level. There is virtually no water in this land, except that from the rivers. There were no roads, so all transport had to be by boat along the rivers. The major centre of population was Baghdad, almost 570 miles upstream from the Gulf.

The campaign


Britain relied heavily on oil to keep its dominant navy at sea. It determined very quickly on the outbreak of the war with Germany to protect its interests by occupying the oilfields and pipeline near Basra. It then pushed out a force to seize the river junction at Qurna.

  • HM ships "Espiegle" and "Dalhousie" entered the Shatt-al-Arab and moved to Muhammerah (29 September 1914)
  • The convoy carrying Indian Expeditionary Force 'D' left Bombay (16 October 1914)
  • The capture of Basra (21 November 1914)
  • The capture of Qurna (3 - 19 December 1914)

1915 saw some tactical moves by the British to seize important or threatening points beyond Basra. After an early string of cheap successes, eyes increasingly fell on the lure of the Mesopotamian capital, Baghdad. The 6th (Poona) Division advanced upriver, leaving a very thinly stretched supply line of hundreds of miles behind it, only to receive a bloody repulse at Ctesiphon. A ragged and dispiriting retreat back to Kut-al-Amara began.

  • The Turkish attempts to recapture Basra (The Miracle of Shaiba) (11 - 14 April 1915)
  • The Capture of Nasiriyeh (27 June - 24 July 1915)
  • The first advance on Baghdad (including the Capture of Kut-al-Amara) (12 September - 7 October 1915)
  • The Battle of Ctesiphon (22 - 24 November 1915)
  • The retreat to Kut-al-Amara (25 November - 3 December 1915)


The Turks pursued the retreating 6th (Poona) Division to Kut, and soon surrounded and cut it off. British forces in Mesopotamia were now growing, the arrival of the experienced 3rd (Lahore), 7th (Meerut) and 13th (Western) Divisions bringing a significant increase in strength. These formations were ordered to advance north along the Tigris to relieve Kut. They ran into strong and stoutly defended lines and suffered some hard knocks; although they got close to Kut, the garrison there was surrendered on 29 April 1916. It was an enormous blow to British prestige and a morale-booster for the Turkish Army.

  • The siege of Kut-al-Amara (7 December 1915 - 29 April 1916)
  • The efforts to relieve Kut
    • The Battle of Sheik Sa'ad (7 January 1916)
    • The Battle of the Wadi (13 January 1916)
    • The Battle of the Hanna (21 January 1916)
    • The Attack on the Dujaila Redoubt (7 - 9 March 1916)
    • The Battles of the Hanna and Fallahiyeh (5 - 8 April 1916)
    • The Battles of Bait Aisa and Sannaiyat (7 - 22 April 1916)
  • The surrender of the Kut garrison (29 April 1916)


Lessons were learned. Following the fall of Kut, the British ordered Major-General Stanley Maude to take command of the British army in Mesopotamia. He introduced new methods, which culminated in a decisive defeat of the Turks in February 1917 and the capture of Baghdad in March 1917. On this day, the Berlin-Baghdad railway was captured, and German schemes for Turkey were finished. Given the continually depressing news in France and elsewhere, this was a sinificant and newsworthy achievement. British forces (and Russians, advancing from the north and east) closed in on the Turks throughout the autumn of 1917, and into the Spring of 1918. Despite making great advances, however, and the additional pressure coming from the north-west where British forces in Palestine defeated the Turks, no decisive victory was gained.

  • The Battle of Mohammed Abdul Hassan (9 January 1917)
  • The Battles of the Hai salient, Dahra Bend and the Shumran Peninsula (11 January - 24 February 1917)
  • The Capture of Baghdad (11 March 1917)
  • The Battle of Istabulat (21 April 1917)
  • The Battle of 'The Boot' at Band-i-Adhaim (30 April 1917)
  • The Battle of Tikrit (5 November 1917)


  • The Action of Khan Baghdadi (26 March 1918)
  • Turkey signs Armistice (1 October 1918)

The cost

Like Gallipoli, conditions in Mesopotamia defy description. Extremes of temperature (120 degrees F was common); arid desert and regular flooding; flies, mosquitoes and other vermin: all led to appalling levels of sickness and death through disease. Under these incredible conditions, units fell short of officers and men, and all too often the reinforcements were half-trained and ill-equipped. Medical arrangements were quite shocking, with wounded men spending up to two weeks on boats before reaching any kind of hospital. These factors, plus of course the unexpectedly determined Turkish resistance, contributed to high casualty rates.

  • 11012 killed
  • 3985 died of wounds
  • 12678 died of sickness
  • 13492 missing and prisoners (9000 at Kut)
  • 51836 wounded
