I read the book by Britton Davis. He calls it "the truth about Geronimo". But in reality, it is "the truth about Britton Davis trying to catch Geronimo"! The book is all about Britton Davis, not so much about Geronimo! I will say this for Davis - he was brave and in excellent physical condition. Trying to catch the fleeing Chiricahuas over the mountains of Mexico was exhausting and dangerous work!
I will say this for Geronimo. He was chased by a white man who was half his age, but Geronimo still evaded his pursuer in the mountains. Hahahahahaha!
As your article implies, the real truth was connected with the role of the Apache Scouts. They were in excellent physical condition - they were the real "disruptive force" to the lifestyle of the traditional Chiricahuas who were "on the run". It was very dangerous work to be a Scout, and I am sure - not much money or reward. It is surprising that any man would do the work at all.
