During Britain's transition to war against Revolutionary France in 1793, the administration of William Pitt expanded Britain's traditional military embargoes on enemy commerce to include grain-a policy that redefi ned "military stores" to include foods alongside other materials required for warfare. Th e goal of this blockade was to use starvation as a political weapon for ending the war by forcing France's National Convention to decide between feeding its civilian population and feeding its armies. Th e policy never received full support in London, however, and the National Convention in France prioritized feeding its soldiers over its people. Although the British eff ort to manipulate Europe's international food system to serve Britain's diplomatic and military ends was largely a failure, the redefi nition of grain as military material reshaped the signifi cance of food and agricultural geography in European military strategy at the turn of the nineteenth century.
