treaty was opposed by most of the Cherokee people, as it was not approved by the Cherokee National Council, and it was not signed by Principal Chief John Ross. The Cherokee National Council submitted a petition, signed by thousands of Cherokee citizens, urging Congress to void the agreement in February 1836. Despite this opposition, the Senate ratified the treaty on March 1836, and the Treaty of New Echota thus became the legal basis for the Trail of Tears. Only a fraction of the Cherokees left voluntarily. The U.S. government, with assistance from state militias, forced most of the remaining Cherokees west in 1838. The Cherokees were temporarily remanded in camps in eastern Tennessee. In November, the Cherokee were broken into groups of around 1,000 each and began the journey west. They endured heavy rains, snow, and freezing temperatures. When the Cherokee negotiated the Treaty of New Echota, they exchanged all their land east of the Mississippi for land in modern Oklahoma and a $5 million payment from the federal government. Many Cherokee felt betrayed that their leadership accepted the deal, and over 16,000 Cherokee signed a petition to prevent the passage of the treaty. By the end of the decade in 1840, tens of thousands of Cherokee and other Indian nations had been removed from their land east of the Mississippi River. The Creek, Choctaw, Seminole, and Chicksaw were also relocated under the Indian Removal Act of 1830. One Choctaw leader portrayed the removal as "A Trail of Tears and Deaths", a devastating event that removed most of the Indian population of the southeastern United States from their traditional homelands. Terminology The forced relocations and ethnic cleansings of the Indian nations have sometimes been referred to as "death marches", in particular when referring to the Cherokee march across the Midwest in 1838, which occurred via a predominantly land route. Indians who had the means initially provided for their own removal. Contingents that were led by conductors from the U.S. Army included those led by Edward Deas, who was claimed to be a sympathizer for the Cherokee plight. The largest death toll from the Cherokee forced relocation comes from the period after the May 23, 1838 deadline. This was at the point when the remaining Cherokee were rounded up into camps and placed into large groups, often over 700 in size (larger than the populations of Little Rock or Memphis at
