The whole Nation became indignant at this treatment, and such was the feeling against the agent that he deemed it prudent to retire from the agency. General Wiley Thompson was appointed to succeed him. General Clinch was appointed to the command of the troops, and every preparation was made to insure the speedy removal of the Indians and Exiles west of the Mississippi. In the meantime, the Creeks learning that a tract of country was, by the additional treaty, agreed to be set off to the separate use of the Seminoles, saw clearly the influence which Abraham had exercised in the matter, and, fearing their own designs for obtaining slaves would be defeated through their principal chiefs, addressed a protest to the Hon. Lewis Cass, then Secretary of War, remonstrating against the policy of giving the Seminoles a _separate_ country. These chiefs were sagacious men, who had attained distinction with the Creeks by their manifestation of superior intelligence. Two of them, Rolley McIntosh and Chilley McIntosh, sons of a Scotch trader who lived with the Indians, had been educated, and were regarded as among the able politicians of the day. They, together with "Toshatchee Mieco" and "Lewis," urged the propriety of uniting the two tribes as one people, without any separate organization. The next day they addressed another letter to Secretary Cass, giving additional reasons and arguments why the Seminoles should not have separate lands.[70] The President had already adopted the policy of compelling the Seminoles to unite under one government with the Creeks: and this stipulation for _separate_ lands was introduced into the "additional treaty," by commissioners who were not fully informed of the President's views. This compact, entered into at Fort Gibson, erroneously called an "additional treaty," was known to be void: neither the Seminole chiefs nor the United States commissioners had authority to negotiate any treaty whatever; and this stipulation, for holding separate lands by the Seminoles, appears to have been totally disregarded by the Executive, as will more fully appear hereafter.
