Between Two Worlds: A Rajput Officer in the Indian Army, 1905-21 describes two societies in early twentieth century colonial India-the British governmental and military society and the regional Rajasthan aristocracy. The book portrays the pioneering experiences of Captain (later Major-General) Amar Singh, an aristocrat of Jaipur State, in the peacetime cantonments of Mhow (1906-14) and New Delhi (1918-19), on the Western and Mesopotamian fronts of World War One, and on the Northwest Frontier (1919-21) during the Pathan uprising. Singh's personal story, revealed through his diary, details Indo-British cultural collaboration.
