The Navajo were in a vast area and were adept at hiding. There were probably a dozen slaving expeditions out at the time he was there. I think that he rounded up only about 25-35% of the Navajo. The rest took to the hills. It was enough to break the back of the Navajo as a cohesive force. There are still numerous stories on the reservation of people watching from hiding as their brethern were dragged off to the Long Walk. There were also thousands of Navajo being held as slaves up and down the Rio Grande Valley.
To this day the mention of the name Kit Carson will draw you stares of bitter hatred from the old people on the Reservation. In some cases it is the only English name they know.
I keep reading that Navajos and Apaches speak a similar language, meaning that in the past their tribes were the same or came from the same place, from up in Canada. While the Pueblos apparently descended from the local Anasasi, who descended from the more ancient local Indians who were here for thousands of years.
I NEVER mention the name Kit Carson out here. In fact, I cant even mention Columbus.
There are still remote trading posts on the large Navajo reservation that use a barter system, the older Navajos dont speak any English, and they trade rugs that they make and other stuff like mutton for regular food goods. You probably know this, but Im saying it for the others.
