Wellington’s scheme for the clearing of the country-side in face of the enemy had long been thought out. It included not merely the evacuation of the towns and villages, but the destruction of bridges, mills, even ovens; the removal of all animals and means of transport, the destruction of all food-stuff that could not be carried off, the burning of all ferry-boats and other small craft on the navigable rivers. ‘The moment that the enemy crosses the frontier,’ he wrote to Beresford, ‘the governor of the province of Estremadura must be told that it is necessary to order all carts, carriages, and other means of conveyance, with all the provisions they can carry, away. He ought to have all his arrangements prepared for ordering them off as soon as the French approach. The Captains Mor[196] and their Ordenança must be prepared to give the enemy all the opposition in their power, not by assembling in large bodies, but by lying out in the mountains and the strong parts of the roads, annoying their patrols and small parties, and interrupting their communications[197].’ This comes from an order of February: by August, when a new harvest had been gathered in, the question of the destruction of food stuffs became more difficult. The peasantry, as was natural, persisted in hiding rather than burning what could not be carried off. By one means or another a certain number of these concealed stores, even when buried in pits or removed to remote ravines, were discovered by the French, and enabled them to prolong their precarious stay in front of the Torres Vedras lines.
