Scorched earth
A scorched-earth policy is a military strategy that aims to destroy anything that might be useful to the enemy while it is advancing through or withdrawing from a location. Any assets that could be used by the enemy may be targeted, for example food sources, water supplies, transportation, communications, industrial resources, and even the locale's people themselves.

In 1945, Adolf Hitler ordered his minister of armaments Albert Speer to carry out a nationwide scorched-earth policy, in what became known as the Nero Decree. Speer, who was looking to the future, actively resisted the order, just as he had earlier refused Hitler's command to destroy French industry when the Wehrmacht was being driven out of France and he managed to continue doing so even after Hitler became aware of his actions.
