This chapter examines the military and economic centrality of granary networks to the Nationalists’ war effort. The centralization of land tax and its collection in kind restored the granary’s historic importance as the storehouse of state wealth. However, the chapter moves away from the dominant portrayal of granaries as economic stabilizers and disaster relief mechanisms to emphasize their strategic significance for an agrarian state at war. In examining the government’s establishment of a national grain reserve scheme and its construction of granary networks throughout its territories, the chapter presents the granary as an integral part of wartime economic policy and military logistical organization. It also studies the amassing of grain reserves in southwestern Yunnan for the Chinese Expeditionary Force after the fall of Burma, a significant but forgotten effort. Unlike most studies, it pays close attention to day-to-day operations, such as checking the quality of delivered grain and preventing spoilage. These everyday procedures are a window into how the demands of war concretely shaped civilian life and illustrate that granaries were key sites of state-society interaction.
