This book traces an emotional and revolutionary history of the Second World War, through the prism of the Quit India Movement in Bengal. While this last mass-movement of colonial India echoed at an all-India level, Bengal was exceptional in the 1940s due to its geostrategic position after Japan's entry and Calcutta's industrial base. Rooted in the domestic and international context of War, the author explores three interconnected themes – that the Quit India movement in Bengal was not so much the product of 'war of ideas', but was imagined and sustained by a complex synthesis of both Gandhian and revolutionary ideas of political 'action', the violent response by the colonial state in India reveals complex undercurrents of imperial anxieties of a post-war political order where it was fast losing out to the resurgent USA and the conflict between legal and moral ideas of political responsibility displayed by imperial Britain and Gandhi.
