This collection consists of a handwritten copy of the proceedings of treaty negotiations between the Choctaws and the United States commissioners from November 10 through November 16, 1826. The Choctaws were represented by thirteen leaders, including Chief Tapena Homa (General Hummingbird), James L. McDonald, Israel Folsom, and interpreter Major J. L. Pichlyn. The U. S. commissioners included Superintendent of Indian Affairs and former Missouri Governor William Clark and Generals John Coffee and Thomas Hinds.
Two treaty proposals were discussed. The first required the Choctaws to cede all their lands east of the Mississippi to the United States in return for lands west of the river, money, transportation and provisions, and reservations for the elderly unable to travel. The second called for the cession of only a portion of their territory adjacent to Monroe County, Mississippi, by the Tombigbee River. The Choctaws rejected both proposals.
Recorded also are the subsequent negotiations between Choctaw leader David Folsom and Superintendent William Clark, in which Folsom sought Clark's aid to avoid conflict with the Delaware after an accidental killing of some of their tribe by Folsom's warriors, and Clark's proposal that the Choctaws offer peace to the Osage tribe and end their war with them. The proceedings describe the speeches of the U. S. commissioners at length, as well as the response made by the Choctaw leadership, and the subsequent exchange of David Folsom and William Clark.
