Almost two million volunteers served the Indian army in the Great War, always under British regimental officers, high commanders and staff. 150,000 of them were long-serving pre-war professional soldiers; most of the remainder were wartime recruits, drawn from across South Asia. Half of the Indian soldiers were sent overseas, and those who returned did so with a different outlook on life - for some it lit the spark for Jihad and for even more it led to a desire for Independence. In most histories of the war, the Tommies, pals and poets have dominated the tales - but what of the war as experienced by their Indian counterparts? This remarkable, fresh take on WWI sets this right, telling the Indian army's story of 1914-18 through the voices of the service's officers and ranks, and of the princes, priests, prostitutes and others who encountered them across the continents.
