I haven’t read this particular book but I’ve read others on this interesting subject. The Comanche were late arriving in the U.S. Southwest and when they showed up they ran the Apaches and Spanish out. They were feared and hated by nearly all of their neighbors and it was due mainly to their horsemanship. They are said to have been some of the best cavalry soldiers in the history of the world. That is saying a lot since they didn’t have the horse until after the Spanish arrived.
Another good book on this subject is Lone Star by T.R. Ferenbach.
They were known as the lords of the southern plains, which is where most of the Buffalo were. The and the Sioux (I think) held a council on the Arkansas R, and mdd that a dividing lines of their territories. As warriors, the Comanche were outmatched by no one. The Mexicans allowed Austin to establish a colony in Texas to serve as a buffer between them and the old Spanish settlements. Liberals, in their usual condescending way, treat indians as victims. The Comanches were wolves rather than lambs.
An excellent book.
The Comanche were the only true horse warriors. Other tribes rode horses to the battle, then dismounted and fought on foot.
