Scorched-earth defense
The scorched-earth defense is a form of risk arbitrage and anti-takeover strategy.
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.
