India Command

Following the Kitchener Reforms of 1903 during the British Raj, the Commander-in-Chief, India, enjoyed control of the Army of India and answered to the civilian Viceroy of India. "The C-in-C India’s HQ was known as the General Headquarters (GHQ India) and acted as the superior HQ for all services to fulfil their requirements." The Commander-in-Chief's staff was overseen by the Chief of the General Staff. General Headquarters India (GHQ India) was based in Calcutta and Simla (the winter capital of the Raj) until the seat of power moved to New Delhi in 1911.

In addition to India, it was responsible at varying periods for parts of the Middle East (in particular Aden Settlement and, later, Aden Colony, as well as Iraq and Persia). For significant periods before the creation of South East Asia Command (SEAC) in 1943, the C-in-C India was also responsible for Ceylon and Burma.

The Commander-in-Chief, India, had some 2,000 officers and 2.5 million troops under his command in 1945. GHQ India was redesignated Army HQ in 1947 when India was partitioned.
