The Plan proposed Spanish removal of the Cherokees, Chickasaws, Choctaws,and Creeks from the area east of the Mississippi River and north of the 31st parallel and their resettlement in the Spanish territory bounded by the Mississippi, Red, and Osage Rivers. There, it was hoped, they might form a protective buffer against the incursions of Anglo-Americans into the Spanish territories of Texas, New Mexico, and northern Mexico. The incoming tribes would be urged to make peace with the Indians already residing and hunting on the land. All would be bound by a treaty of mutual friendship and would be ruled by a single chief. The document estimated the number of persons involved in the move and the number into which they would be assimilated. All Indians would be given sufficient territory for hunting grounds, which would be interdicted to white hunters. White settlers would be established along the Mississippi to prevent the entrance of unauthorized persons and to protect the Indians. It would be advantageous to instruct a group of Creoles or Europeans in the Indians' ways that they might dwell among them and supervise the system, along with a military regiment of 500 to 800 men, who would be assigned, one or two soldiers for every hundred hunters.
