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
During the wars with Native American tribes of the American West, under James Carleton's direction, Kit Carson instituted a scorched-earth policy, burning Navajo fields and homes, and stealing or killing their livestock. He was aided by other Indian tribes with long-standing enmity toward the Navajos, chiefly the Utes. The Navajo were forced to surrender due to the destruction of their livestock and food supplies. In the spring of 1864, 8,000 Navajo men, women and children were forced to march 300 miles to Fort Sumner, New Mexico. Navajos call this "The Long Walk." Many died along the way or during the next four years of their internment.
