The convention began on October 10 with a talk by "Sharp Knife", the nickname of Jackson, to more than 500 Choctaws. Pushmataha accused Jackson of deceiving them about the quality of land west of the Mississippi. Pushmataha responded to Jackson's retort with "I know the country well ... The grass is everywhere very short ... There are but few beavers, and the honey and fruit are rare things." Jackson resorted to threats, which pressured the Choctaws to sign the Doak's Stand treaty. Pushmataha would continue to argue with Jackson about the conditions of the treaty. Pushmataha assertively stated "that no alteration shall be made in the boundaries of the portion of our territory that will remain, until the Choctaw people are sufficiently progressed in the arts of civilization to become citizens of the States, owning land and homes of their own, on an equal footing with the white people." Jackson responded with "That ... is a magnificent rangement and we consent to it, Citizenship, readily." Historian Anna Lewis stated that "Apuckshunubbee", a Choctaw district chief, was blackmailed by Jackson to sign the treaty. On October 18, the Treaty of Doak's Stand was signed.
