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 1827, Ibrahim Pasha led an Ottoman-Egyptian combined force in a campaign to crash Greek revolutionaries in the Peloponnese. In response to Greek guerrilla attacks on his forces in the Peloponnese, Ibrahim launched a scorched earth campaign which threatened the population with starvation and deported many civilians into slavery in Egypt. He also allegedly planned to bring in Arab settlers, in order to replace the Greek population. The fires of burning villages and fields were clearly visible from Allied ships standing offshore. A British landing party reported that the population of Messinia was close to mass starvation. Ibrahim's scorched-earth policy caused much outrage in Europe, being one of the reasons the Great Powers (Great Britain, France and Russia) decisively intervened against him in the Battle of Navarino.
