Julian might expect, that a conqueror, who possessed the two forcible instruments of persuasion, steel and gold, would easily procure a plentiful subsistence from the fears or avarice of the natives. The extensive region that lies between the River Tigris and the mountains of Media.was in a very improved state of cultivation. In the year CE 363, the Emperor Julian's invasion of Persia was turned back by a scorched-earth policy: However, the story that they salted the earth is apocryphal. The buildings were torn down, their stones scattered so not even rubble remained, and the fields were burned. After the end of the Third Punic War in 146 BCE, the Roman Senate also elected to use this method to permanently destroy the Carthaginian capital city, Carthage (near modern-day Tunis). That caused immense problems for the Romans, but the Roman military triumphs over the Gallic alliance showed that alone not to be enough to save Gaul from subjugation by Rome.ĭuring the Second Punic War in 218–202 BCE, the Carthaginians used the method selectively while storming through Italy. They thus ravaged the countryside of what are now the Benelux countries and France. The second case shows actual military value: during the Great Gallic War the Gauls under Vercingetorix planned to lure the Roman armies into Gaul and then trap and obliterate them. After the Helvetii were defeated by a combined Roman and Gallic forces', the Helvetii were forced to rebuild themselves on the shattered and plains they themselves had destroyed. The first was used when the Celtic Helvetii were forced to evacuate their homes in Southern Germany and Switzerland because of incursions of unfriendly Germanic tribes: to add incentive to the march, the Helvetii destroyed everything they could not bring. Two of the first uses of scorched earth recorded both happened in the Gallic Wars. The system of punitive destruction of property and subjugation of people when accompanying a military campaign was known as vastatio. The Greek mercenary general Memnon of Rhodes unsuccessfully suggested to the Persian satraps to use a scorched-earth policy against Alexander the Great, who was moving into Asia Minor. The Greek general Xenophon recorded in his Anabasis that the Armenians, as they withdrew, burned their crops and food supplies before the Ten Thousand could advance. The Scythians, who were nomadic herders, evaded the Persian invaders and retreated into the depths of the steppes after they had destroyed food supplies and poisoned wells. The Scythians used scorched-earth methods against the Persian Achaemenid Empire, led by King Darius the Great, during his European Scythian campaign. The concept of scorched-earth defense is sometimes applied figuratively to the business world in which a firm facing a takeover attempts to make itself less valuable by selling off its assets.
Also notable were the Russian army's strategies during the failed Swedish invasion of Russia, the failed Napoleonic invasion of Russia, the initial Soviet retreat commanded by Joseph Stalin during the German Army's invasion during the Second World War, and Nazi Germany's retreat on the Eastern Front.
Notable historic examples of scorched-earth tactics include William Tecumseh Sherman's March to the Sea in the American Civil War, Kit Carson's subjugation of the American Navajo Indians, Lord Kitchener's advance against the Boers, and the setting on fire of 605 to 732 oil wells by retreating Iraqi military forces during the Gulf War. It may overlap with, but is not the same as, punitive destruction of the enemy's resources, which is usually done as part of political strategy, rather than operational strategy. The practice can be carried out by the military in enemy territory or in its own home territory while it is being invaded. However, anything useful to the advancing enemy may be targeted, including food stores and agricultural areas, water sources, and even the local people themselves, though the last has been banned under the 1977 Geneva Conventions. Any assets that could be used by the enemy may be targeted, which usually includes obvious weapons, transport vehicles, communication sites, and industrial resources. A scorched-earth policy is a military strategy that aims to destroy anything that might be useful to the enemy.
