34th Indian Brigade

The 34th Indian Brigade was an infantry brigade of the British Indian Army that saw active service in the Mesopotamian campaign in the Indian Army during the First World War. It was reformed for the Second World War as the 34th Indian States Forces Infantry Brigade.

History
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. 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) Division besieged at Kut. 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. 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. The brigade joined the newly-formed 17th Indian Division, swapping places with the 50th Indian Brigade. It remained with the division for the rest of the war, taking part in the Action at Fat-ha Gorge on the Little Zab (23–26 October 1918) and the Battle of Sharqat (28–30 October 1918).
