The Sepoy Army of the colonial Indian Army was the pillar of Britain`s India Empire. This workhorse of British imperialism was a hybrid organization which integrated some elements of the Indian social structure and cultural ethos with the western military organisation. Nevertheless, it remains marginal in Indian historiography. With the aid of a conceptual framework of Military Synthesis model, this book focuses on the institutional aspects of the Sepoy Army in the second half of the nineteenth century. The study examines the literature on recruitment and evaluates the problematic of the Sepoy Army`s command structure. This book will be of great interest to scholars and teachers of military history.
