two divisions52nd and 74th were transferred to France in April; they were replaced by the 3rd and 7th Divisions from Mesopotamia;
nine yeomanry regiments were dismounted, converted to machine gunners and sent to France at the end of the same month; the 4th and 5th Cavalry Divisions were reformed with Indian cavalry regiments withdrawn from France and the 15th Cavalry Brigade already in Egypt;
the 10th, 53rd, 60th, and 75th Divisions were reduced to a single British battalion per brigade. They were reformed with nine Indian infantry battalions and an Indian pioneer battalion each.
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, 151st Sikh Infantry, 152nd Punjabis, 153rd Punjabis, 154th Infantry, 155th Pioneers, 156th Infantry and the 11th Gurkha Rifles. 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.
History
Nomenclature
Oddly, the designation of the regiment varied between the battalions. The 1st and 2nd Battalions were 151st Sikh Infantry whereas the 3rd Battalion was 151st Punjabi Rifles, hence 1st Battalion, 151st Sikh Infantry, 2nd Battalion, 151st Sikh Infantry and 3rd Battalion, 151st Punjabi Rifles. Gaylor states that the 2nd Battalion was 151st Indian Infantry; it is notable that no other Indian infantry regiment incorporated Indian in their titles at this time. Other sources designate both the 2nd and 3rd battalions as 151st Infantry.
Formation
The 151st Sikh Infantry / 151st Punjabi Rifles was formed of three battalions in May 1918. The 1st Battalion was formed in Mesopotamia with companies posted from battalions serving in the 17th and 18th Indian Divisions. It was transferred to India in June 1918 and later took part in the Third Anglo-Afghan War in 1919 as part of the Kohat Brigade. In contrast, the 2nd and 3rd Battalions were formed in Palestine with companies posted from battalions serving in the theatre particularly from the 3rd and 7th Divisions. They were assigned to British divisions and took part in the final Allied offensive of the Sinai and Palestine Campaign.
