After the War of 1812, Tishomingo retired to his farm until white settlers came onto his land. He traveled to Philadelphia and Washington, D.C., and was a principal signatory of the treaties of 1816 and 1818 as well as the 1832 Treaty of Pontotoc. In 1837, a final treaty forced him and his family to relocate to Indian Territory.[3]
Chief Tishomingo was reported to have had a kidney stone operation March 25, 1821, in Columbus, Mississippi performed by Dr. Henderson and Dr. Barry. The article stated, "...the patient is supposed to be in his 63d year..." This would place his birth approximately in the year 1758.[4]
Death
According to Tishomingo's son Richard, Tishomingo died c. 1837 on Brushy Creek in the Choctaw Nation on the same day as his wife "U-Kuth-Le-Ya" died. This was during the time both Chickasaw and Choctaw tribes resided together in Indian Territory. Both he and his wife's burials were witnessed by two Chickasaw Warriors who had served with Tishomingo in the War of 1812. They gave their testimony attesting to the facts of the couple's deaths to the Indian Agent, Douglas H. Cooper, on September 27, 1859, in accordance with the requirements of a Bounty Land Application of Richard.[5]
