saw service in the North-West Frontier of India, gaining the Battle Honour "North-West Frontier 1915–17" in the process. In 1917 a 3rd Battalion was raised for home service in India. During the period that they had served on the Western Front in France the men of the 1st Gurkhas had found the conditions quite different from those that they were used to, however, they acquitted themselves commendably, performing with distinction in the many battles they took part in, proving the capability of the Gurkhas once more. The war formally ended on 11 November 1918 with the signing of the Armistice. The regiment was awarded eleven Battle Honours and four Theatre Honours during the war. Inter war years In 1919, the 1st and 2nd Battalions saw service during the brief Third Afghan War for which they gained the Theatre Honour "Afghanistan 1919".

Within a few days they were again in action but were out-numbered and sustained heavy casualties during the engagement at the Slim River Bridge on 7 January.
