The 34th Indian Brigade was formed in Mesopotamia in December 1915 with four battalions newly arrived from India. It joined the 12th Indian Division to replace the 33rd Indian Brigade that was broken up on 7 December.[3] While with the division, it took part in the Affair of Butaniya on 14 January 1916. The division never reached full strength as units were constantly detached to support the efforts to relieve the 6th (Poona) Divisionbesieged at Kut.[4] The division was broken up on 10 March 1916 and the brigade joined Corps Troops before it was posted to the new 15th Indian Division in May 1916.[5]
15th Indian Division
The 15th Indian Division was formed on 7 May 1916 to replace the 12th Indian Division on the Euphrates Front; the brigade joined the division on formation. It remained with the division on the Euphrates Front until August 1917. The only significant action that the brigade took part in as part of the 15th Indian Division was the action of As Sahilan on 11 September 1916.[6]
At the end of the war, the 17th Division was chosen to form part of the occupation force for Iraq. It took part in the Iraq Rebellion in 1920. In August 1923, the division was reduced to a single brigade; the last British troops left in March 1927 and the Indian ones in November 1928.[7]
