 The titles of these 2nd Line units would be the same as the original, but distinguished by a '2/' prefix.In this way duplicate battalions, brigades and divisions were created, mirroring those TF formations being sent overseas.The Duke of Cornwall's Light Infantry experienced a shortfall in volunteers, and so many Overseas Service men had to be transferred from the 1/5th DCLI to bring the 1/4th up to strength that the 1/5th was withdrawn from the Devon & Cornwall brigade and replaced by the 1/6th Devons on 16 September; 1/5th DCLI later became a pioneer battalion on the Western Front.
