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.
Scorched earth
A military expedition led by U.S. Army Colonel Ranald S. Mackenzie was sent to the Texas Panhandle and Oklahoma Territory Panhandle area in 1874 to remove the Indians to reservations in Oklahoma. The Mackenzie expedition captured about 1,200 of the Indians' horses, drove them into Tule Canyon, and shot them all. Denied their main source of livelihood and demoralized, the Comanche and Kiowa abandoned the area (see Palo Duro Canyon).
