It appears to me that "Cha-la-ki" is the same as "Tsa-la-gi" which is the origin of the name "Cherokee". I assume, therefore, that in Feb. 1862 -- when the Cherokee Nation was firmly in Southern control -- that the Cha-la-ki judicial district was probably the northern Indian Territory (Cherokee and Muscogee Nations). I would like to see the text of the Act of Congress.
"Tash-co-homma" it would appear is "Tuskahoma". This is a Choctaw word meaning something like "Red Warrior" (Tushka=Warrior and Homma=Red). Wasn't Boggy Depot the site of the courthouse for the Tuskahoma District?
I think this is an error by Maj Gen J.J. Reynolds, who wrote the report. "Chata Tamaha" is not Camp Napoleon. Chata Tumaha is Armstrong Academy and was designated at the Choctaw Capital from 1863-1885 when it was moved to Tuskahomma. It is a Choctaw word meaning "Choctaw City". I believe Reynolds heard both names and thought it was one event instead of two.
The meeting at Camp Napoleon was on May 24-26, 1865 and the Chata Tamaha meeting was on June 15, 1865. The Camp Napoleon meeting was to ally with the Plains Tribes to fight against the North but turned into more of a peace treaty between the tribes while they tried to find out what was happening in the East (i.e., rumors of the fall of the Confederacy). The subsequent meeting at Chata Tamaha (Armstrong Academy) was to cease hostilities and began negotiation with US authorities.
I believe that "Cleata Yamaha" is a mistranscription (or misspelling, or both) of "Chata Tamaha".
