Simultaneously, the Nepalese government agreed to maintain recruitment at a level that would sustain the existing British Gurkha units and allow the establishment of additional ones.
The battalions were increased to thirty-three with the addition of 55,000 new recruits and Gurkha units were placed at the disposal of the British high command for service on all fronts.
Many volunteers were assigned to non-combat units, such as the Army Bearer Corps and the labour battalions but they also were in combat in France, Turkey, Palestine and Mesopotamia.
