At the outbreak of the
First World War, the
7th (Meerut) Division was mobilized in August 1914, and sailed from
Bombay on 20 September for the
Western Front. 39th Royal Garhwal Rifles went with the 7th (Meerut) Division to fight in World War One on the Western Front. The
7th Meerut Divisional Area was formed in September 1914 to take over the area responsibilities of the 7th (Meerut) Division. It took over the units left behind by the original division and started to form brigades to control them "the
14th (Meerut) Cavalry Brigade in November, the
Bareilly and
Delhi Brigades in December 1914, and the
Dehra Dun Brigade in March 1915". However, the
Garhwal Brigade was not reformed until April 1917. The division served within India throughout the war (although the Meerut Cavalry Brigade was mobilized for the
Third Anglo-Afghan War in 1919), initially under
Northern Army, then
Northern Command from January 1918. and was broken up in 1920. ==Order of battle==
