Scorched Earth (disambiguation)
Scorched earth is the military strategy or operational policy of destroying everything useful to the enemy in areas that cannot be defended.
Fantastic War
The allied army eventually stopped the Bourbon army’s march toward Lisbon in the mountains near Abrantes (which by its position dominated the country) and used a scorched earth strategy - in cooperation with the rural population - to starve the invaders: peasants abandoned their villages, destroying or taking with them all the food, while the guerrillas attacked their logistic lines. The invaders had to choose between stay and starve or withdraw.
