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.
History of guerrilla warfare
To counter these tactics, the British under Kitchener interned Boer civilians into concentration camps and built hundreds of blockhouses all over the Transvaal and Orange Free State. Kitchener also enacted a scorched earth policy, destroying Boer homes and farms. Eventually, the Boer guerrillas surrendered in 1902, but the British granted them generous terms in order to bring the war to an end. This showed how effective guerrilla tactics could be in extracting concessions from a militarily more powerful enemy.
