Scorched earth policy
It is commonly called a "scorched earth" policy. Hitler ordered Albert Speer to institute a scorched earth policy near the end of the war. Without telling Hitler, Speer ignored the command (he revealed this to Hitler only a few days before Hitler committed suicide). Speer's refusal to, literally, "burn Germany to the ground" is part of why when he was tried at Nuremberg, he got 20 years instead of life or execution.
scorched earth means that in war the losing country burns the city to the ground*EDIT- Scorched earth refers to the burning of land so that it is rendered useless. This was primarily used by Stalin to prevent Napoleon and Hitler from gaining Russian lands. They did this because they were undoubtedly losing against France and Germany so they figured "we might as well make their lives worse if we're gonna lose."
