Yeppers, the Comanche and Kiowa didn't really "settle up" with the Tonkawa until they got them penned up on the res in Oklahoma.
I think that the reason Gynne says the Tonks were always loseing was because they were outnumbered by the Comanche by about ten to one or more.
Our own Confederacy was reduced to "always losing" by the end of the war. In our case, it was due to the war of attrition waged by Grant and Sherman. This may have been the case in the Tonk's war with the Comanch. The Comanch simply wore them down with numbers.
The Karankawas were a highly feared, cannibalistic tribe too.
