to Britain in April 1930. Joining the 6th Brigade of the 2nd Infantry Division it took part in experiments in infantry mechanisation. It was then sent to Shanghai arriving in November 1937, reinforced by personnel from the 2nd battalion at Port Sudan. In October 1938 the battalion moved to Tientsin and was there when Britain declared war against Germany. The 2nd battalion returned to Britain from Germany in April 1919 as a cadre; the battalion reformed and was sent to Batoum in South Russia in October 1919 to police territorial terms of the Armistice. In July 1920 it was sent to the Izmit in Turkey to police the terms of the Turkish armistice until November. From here they went to India and in February 1927 were deployed to Shanghai to protect the International Settlement. Returning to India in August, it fought against the Mahsuds, relieving the post of Datta Khel in May 1930.

The low number of battalions raised compared to the First World War was due to the increasing specialisation of a more mechanised army and its associated support requirements. Additionally, twenty six battalions of the Home Guard wore the D.L.I. cap badge. After the war Field Marshal Montgomery was to write, The remaining first line territorial battalions once again formed the 151st Infantry Brigade of the 50th (Northumbrian) Infantry Division, initially a two brigade motorised Division. The territorials again raised second line battalions now numbering them sequentially, 10th, 11th and 12th battalions, these were now
