The 155th Pioneers was a pioneer regiment of the British Indian Army. It was formed in Mesopotamia and Palestine in May and June 1918, saw service in the Sinai and Palestine Campaign in the First World War, and was disbanded in 1920.
Heavy losses suffered by the British Expeditionary Force on the Western Front following the German Spring Offensive in March 1918 resulted in a major reorganization of the Egyptian Expeditionary Force:
In fact, the 75th Division already had four Indian battalions assigned, so of the 36 battalions needed to reform the divisions, 22 were improvised by taking whole companies from existing units already on active service in Mesopotamia and Palestine to form the 150th Infantry (3 battalions), 151st Sikh Infantry (3), 152nd Punjabis (3), 153rd Punjabis (3), 154th Infantry (3), 155th Pioneers (2), 156th Infantry (1) and the 11th Gurkha Rifles (4). The donor units were then brought back up to strength by drafts. In the event, just 13 of the battalions were assigned to the divisions and the remaining nine were transferred from Mesopotamia to India in June 1918.
The 155th Pioneers was formed of two battalions in May and June 1918. The 1st Battalion was formed in Mesopotamia in May, by posting complete companies from battalions serving in that campaign, before transferring to Egypt in July. It joined the 2nd Battalion which was formed in Palestine in June with companies posted from battalions already serving in the theatre.
