In 1863, Colonel Kit Carson was ordered to clear the country of Navajo Indians and to resettle any survivors at Fort Sumner in eastern New Mexico, where they could be "civilized." Carson's strategy was the same as that applied against the Plains Indians a little later: He destroyed the Navajo food base by systematically killing their livestock and by burning their fields. Carson's "Long Knives" (his soldiers so named because of their bayonets) also cut off the breast of Navajo girls and tossed them back and forth like baseballs.... Ultimately, about 8,500 Navajos made what they still call the "Long Walk" to captivity at Fort Sumner, three hundred miles away. After they had been there for four years, the Navajo signed a peace treaty that entitled them to a reservation of about 3,500,000 acres, much less than they had held previously.
