After arriving in Egypt, it joined the 10th Indian Division when it was formed on 24 December. It served on the Suez Canal Defences, notably taking part in the Actions on the Suez Canal on 3–4 February 1915. After the defeat of the Turkish attempts to cross the canal, the division was dispersed and the brigade was sent to Gallipoli in April 1915.[3]
The brigade was switched to ANZAC Cove where it was attached to the Australian and New Zealand Army Corps, with which it took part in the Battle of Sari Bair (6–21 August 1915). 1st Battalion, 6th Gurkha Rifles was the only unit to reach the top of the ridge and see the Dardanelles; shelled by the Royal Navy, a Turkish counter-attack drove them off.[6] The brigade's involvement at Gallipoli came at a high price: the 14th Sikhs, alone, suffered 264 killed and 840 wounded while serving at Gallipoli.[7][a]
Independent
On 7 January 1916, the 10th Indian Division was reformed as part of the Suez Canal District, and the brigade joined it. The need to return depleted units that had served in France to India meant that this was short-lived. The division was broken up on 7 March and the brigade became an independent formation. It continued to serve on the Suez Canal Defences.[3]
In March 1917, the Egyptian Expeditionary Force started forming the British 75th Division, originally to be made up of Territorial Force battalions arriving from India. In May 1917, to speed up the formation of the division, it was decided to incorporate Indian battalions.[9] To this end, the 29th Indian Brigade was broken up in June 1917 and its battalions posted to 75th Division.[10]
